The MXR Reverb offers players the history of these methods and then some in a standard MXR box, featuring six distinct high end styles exquisitely crafted and tuned by the award-winning MXR design team. It’s got a simple three-knob setup, a hi-fi analog dry path, and a massive 20 volts of headroom thanks to our Constant Headroom Technology™ so that it plays exceptionally well with distortion, modulation, and other effects.

Musicians have a number of utilitarian and creative needs that the MXR Reverb handily addresses. If your recorded signal sounds dull and flat, for example, the MXR Reverb can give it a sense of place and atmosphere, making it sound more natural and alive. The same goes for an acoustically dead venue—adding some reverb can open up a room and breathe some life back into your signal. The MXR Reverb also adds a whole new range of tone-shaping options, whether binding the different elements of your sound together or creating atmospheric, otherworldly environments for your compositions to move and breathe within.

The MXR Reverb’s six different styles can help with all of these uses and more. We encourage you to experiment with all of them, but here’s a quick explanation of what each can bring to your sound.

Nowadays, the EP-3 is difficult to get your hands on—a fully intact, working model could set you back more than $500. If you do get your hands on one, you will be presented with a few potential issues. First, they require a bit of maintenance. Second, their sound and behavior—from model to model and even from use to use with an individual unit—can be inconsistent. Finally, these things are the size of a small amplifier head. Eric Johnson has been known to put one right on his pedalboard—not everyone wants to sacrifice the real estate or lug another 15 lbs. of gear.

The EP101: Secret Sauce at Your Feet

But have no fear—the Echoplex Preamp gives you the sound of that prized box with none of its complications. Dunlop’s Director of New Electronics Jeorge Tripps designed this pedal with the exact same signal path as the EP-3, and to get the secret sauce just right, he used two of the finest EP-3 specimens to ensure that the EP101 nails that classic sound across its range. Now, you can get the EP-3’s sonic mojo in a small stompbox and gig with confidence that it will do what you need it to do to every time you kick the switch.

While the EP101 can boost your signal by up to 11dB, that’s not its main purpose, nor is it a clean and transparent. The EP101 is all about conditioning and sweetening up your tone—use it as a lead boost and crank the Gain control for increased output and some light asymmetrical clipping, use it as a second channel to change up your tone mid-set, or leave it on all the time. However you use it, the Echoplex Preamp will breathe new life into the sound of your whole rig.

Where should you put the EP101 in your signal chain?

As with any pedal, experiment with the Echoplex Preamp’s position in your signal chain. We do have our own suggestions, of course. For a great lead sound, try placing it after your overdrive and distortion pedals to add girth and a bit of volume boost. If you want the pedal’s active all the time or you want to use it as a second channel tone, try placing it either at the beginning or end of your signal chain. Also, got a Way Huge Supa-Puss Delay? Placing the Echoplex Preamp in front of that box will get you close to the EP-3’s tape echo sound. But again, we emphasize, experiment! Find your own sound. The EP101 will add a whole new dimension to your tonal palette.

We sat down with Marcus to talk with him about where his new signature strings fit into the evolution of his musical voice as well as a number of topics, including the importance of tone and finding your own sound. This guy’s a true master, with insights that are valuable to any musician, whether or you play bass or not. Check out the video below for some of the highlights from our conversation—soundtracked by the legend himself. The full interview is packed with even more of Marcus’ masterful insights, so be sure to read that after you watch the video.

How important is tone for a musician?

Marcus: When I started playing bass—I was probably 13 years old, something like that—I wasn’t really at the point where I could tell the difference between the important elements of music: technique, intonation, tone. So I was just going by instinct, just playing the bass. I had a Fender Jazz Bass, and whatever sounded good, even if it was accidentally arrived at, I stuck with it. Later on, I realized that tone is the first thing that impresses people about your sound. That’s the first thing that people are struck by.

All the bass players I admired had a signature sound.

That first note, it makes an impression. I know a lot of great musicians who play some amazing music, but their tone isn’t that great, and you have to get past that as a listener. You have to go, “Ok, my first impression wasn’t that great, but man, he’s playing some great stuff.” But the really, truly great musicians who really make a full impact, to me they have the whole package, and the first element is tone. You hear a guy play that first note and you go, whoa! That’s everything, man. First impressions, right?

All the bass players I admired had a signature sound. Yes, they all had great technique, but you heard one note, two notes, and you knew it was Stanley Clarke, you knew it was Jaco Pastorius, you knew it was James Jamerson. And I really wanted to see if I could find something, maybe not on that level, but something that was easily identifiable as me. Once I got a sound that I liked, I didn’t fool around too much with it. Same bass, same settings, and I just changed the notes, I just changed what I’m playing. But I didn’t really fool around with the sound too much because I felt like I had something that was really identifiable, and that’s so hard to find as a musician. So tone is everything.

When did you first realize you’d found your sound?

Marcus: I was talking to a mentor of mine, a fantastic drummer named Lenny White from my neighborhood in Jamaica, Queens in New York, and I said to him, “Man, I want my own sound, how do I get my own sound?” I was probably 17 at the time, and we had these amazing musicians in the neighborhood who I admired. When we went to these jam sessions, I’d be walking to the club from my car parked two blocks away, and I already knew who was in there because the sounds were so identifiable, even from down the street.

So I’m saying to Lenny White, “Man I really want my own sound, how do you do it?” And he says, “You can’t worry about it, you just keep playing, and keep playing, and then one day, you’re going to hear a recording of yourself and go, ‘Oh that’s me.’” So he gave me some real abstract Karate Kid kind of instructions on how to get your own sound.

Later on, when I’m 21, I get a call from Miles Davis, and he says, “Come to the studio, I’m going to record.” I ran to the studio, and we played, and I’m like, “This is Miles Davis, man, I got to play something good.” And then we heard the playback in the control room, and I remember saying to myself, “Oh wow, that’s me.” I recognized that sound as me. And once you find your own sound, you got to hold on to that, man. You got to hold on tight, because that’s something that a lot of people don’t ever get.

So, I said to myself, now that I have a sound, now I can go to the next level, now I can start to be creative, now I can start to try different techniques, improve my technique, improve my creativity, because I got the first element, the most important element. Sound was really the launching pad for the rest of my playing.

How important is style for a musician?

Marcus: Once when I was talking to Boz Scaggs, he said something that I’ll never forget: “People don’t buy technique. They don’t buy anything but style.” That’s what draws people to an artist—your style, your view of the world, the way you present yourself, but more importantly, the way you see things. You got a lot of great musicians, and then you got artists, and not all great musicians are artists.

I get demos from musicians, and they say, “Check out my demo, I want to make a record.” And the first song is a funk song, the second song is a salsa, and the third song is a bossanova. I say, “Each one is like a completely different player.” And they say, “Well, I want people to know I’m well rounded, that I can do it all.”

You got a lot of great musicians, and then you got artists, and not all great musicians are artists.

That’s really important, but what people want to know is, do you have a unique point of view? And I know the problem, because I was a studio musician for like 25 years. People think they know all the stuff I played on, but I played on hundreds of records that you don’t even know I played on. I’m on Mariah Carey records, Whitney Houston records, where I’m just playing what’s necessary. As a studio musician, you became who you needed to become for each record.

But eventually, I started moving more to an artist mentality where I found my own sound, my own style, and I decided I was going to try to make that sound and that style work in whatever situation I’m in. So, the difference between me 30 years ago and me now is that I have a much clearer point of view about how I want to play and what I think music should sound like. And that’s me really trying to become an artist.

Why work with Dunlop?

Marcus: So the thing about having your own identifiable sound, your own identifiable music, your own identifiable style, is that you still have to grow. You still have to figure out a way, particularly if you’re playing jazz music or any kind of improvisational music to maintain your identity. And it’s a very tricky thing. Because if you stay in the same place, then you’re staying in the same place. And if you change too quickly, you might lose who you are.

You still have to figure out a way to maintain your identity.

Now, everybody has their own version of how to deal with this, but for me, I wanted to continue to evolve. So I’m looking at these Dunlop strings, man, and I’m going, whoa, this maintains what everybody’s known me for, but it has a little bit of my old 17-year-old sound when I was playing more raw, you know what I mean? And I’m already feeling myself wanting to get back to that. This has the best of both worlds.

So it’s a way to grow, by finding this new string. And this is the whole thing: trying to evolve but maintaining who you are at the same time.

Why is it so important to evolve your sound?

Marcus: I always feel like I want to continue to evolve, like I want to push forward. And people ask me, why? Why do you feel like you need to change when you have such a good thing going? But it’s boring otherwise. You know what I mean? I really think that if you’re an artist, your responsibility is to show people the world as it exists today through your eyes. That’s what all artists do. It doesn’t even have to be music, it can be writers, photographers, comedians, they all do the same thing, they all present us with the world as it exists now, but through their own filter, and that’s what makes them interesting.

In the ’8os, everything was really, like, techno, and everything was clean, and everything was very exact because we had just discovered these machines that we could make music with, so we were playing really, like almost in a robotic fashion a lot of times. Because that was where the world was. We had just been introduced to these computers—how do we learn to live with them?

And for a while, computers were dominating. Everything sounded like this, and we found cool ways to do that, but now people are a lot more comfortable with the technology, people are a lot more comfortable with computers. And now things are starting to sound a little bit more natural, at least in a lot of areas of the world and a lot of areas of music.

So for me, I want my sound to sound less high tech. I want to still have a full range of bass and treble, but I want to get a little bit more growl, I want to get a little bit more urgency in my sound. And that’s how I used to play back when I was first starting. In New York, everything was always aggressive, and people didn’t want to hear jazz, so if you were going to play jazz, you had to play with an attitude. We were like 16, 17 years old, and people were like, I don’t know what they’re doing, but they’re really into it, I guess I got to respect them. That’s how we used to hit it. So now, I’m wanting to get back to that.

And in my band, I got like 21, 22, 25 year olds who are feeling like they want to prove themselves, like they want to make a statement, and that’s inspiring me. I want to make sure my sound is in there pushing them.

What is the role of the bass player?

Marcus: A lot of bass players who are solo artists are just sitting there waiting for their solos. But for me, I’m doing just as much work when I’m playing behind you—sometimes more work. It’s a shame that a lot of young bass players don’t recognize how important driving a band is. But that’s what a bass player does, man. You drive the band.

I’m really into that role.—it’s as important to me as playing a great solo. And with these strings, man, with this sound I’m going for, I want to make sure that I’m driving you, that I’m pushing everybody, that I’m pushing the musicians to be creative and reach new heights.

What are you trying to accomplish as an artist?

Marcus: When I first started playing music, I just wanted to be a good musician. My father’s a musician, his father’s a musician—I come from a musical family—so I just wanted to step into the shoes that were laid out for me. And then I’m in my neighborhood in New York, everybody had a band, and I just wanted to be in a good band and just be known as a good musician.

At each step, I just looked to see what else is available from that new step.

And what happens is that, as you get older, you start realizing the possibilities with music. So first, I just wanted to play the bass, I just wanted to be good. Then I saw somebody who had just written a song, he said, “Hey man, here’s a song I wrote.” And I said, “Wow, I would love to write a song on my own.” And that became a goal. And then I saw arrangers making sure that everybody’s part worked together, and I got into that. And then producing. At each step, I just looked to see what else is available from that new step. I’d reach a certain level and go, okay, now what?

And so, for me, at this point, I’m still going, okay, now what? I’m recognizing how powerful music is, how it can communicate things that people have difficulty communicating with words. So we’re playing in Africa, we’re playing in Russia, we’re playing in China, we’re playing all over the world, and we’re able to bring people together who normally wouldn’t come together like that.

So now, what I’m feeling, is how effective, how powerful music can be. That’s my next goal, to take advantage of that, to communicate, try to establish goodwill around the world. It sounds really kind of corny, but when you’re on the stage, man, and you can’t say hello in the audience’s language, but you got like, six, seven thousand people all moving together, all sharing the same emotions, you begin to realize that we all have a lot in common. We just need to establish that first, and then work out the details.

Let’s at least establish that we have a universal commonality, and music is the best example of that.

Relic’d instruments are generally very well-made.

Relic’d instruments are generally of high quality, with a lot of them built by boutique manufacturers who give each instrument they produce a lot of attention.

How did you guys conceive of the Carbon Copy Analog Delay?

Jeorge: When I started at Dunlop, the first thing I wanted to do for MXR was create a delay pedal—the line hadn’t had one since the old days, but players kept asking when we were going to fill that void. So I sat down and made a list of all the things I wanted in an MXR delay pedal: analog circuitry, 600ms of delay time, modulation, a Phase 90-sized housing, and the option to run it on battery power.

Bob: Coincidentally, I already had a design for a 600ms analog delay pedal—it was one of my first projects at Dunlop—and we almost went into production with it in 1997. Unfortunately, the BBD IC (bucket brigade device, integrated circuit) we used went out of production at the last minute, so we had to call the whole thing off.

After Jeorge joined the Dunlop team, we had many conversations about creating a new MXR delay analog pedal, but without the parts needed, it stayed on our “Wouldn’t it be great if…” list. A short time later, though, I learned that the particular BBD IC needed to create my dream delay pedal was available again. We got to work right away.

Was it inspired by any previous circuit designs?

Bob: The Carbon Copy circuit was a new design. It was a culmination of my experience both designing delay pedals as an engineer and using them as a player over the years. Back in 1979, I designed my first chorus/delay rack unit for my own personal use. It used a Reticon R5101 charge-coupled device analog delay line, and it had more knobs and meters than a power plant. The first analog delay pedal I actually bought was a Boss DM2, which I used for pretty much everything—live guitar, recorded vocals, drums, and so on.

Later, while working as a design engineer for SR&D—the company that created the Rockman product line, now owned by Dunlop—I used the Rockman Analog Delay, which had this great, warm analog sound. The problem was that it was housed in a large, half rack box with an AC power cord tethered to it, and its control setup was way too complicated.

By the time I came to Dunlop, I had grown to love the more straightforward MXR approach. I decided that Regeneration, Mix, and Delay controls were all I needed in a delay to make me happy. After that, I concentrated on putting it all into an Phase 90-sized box.

What was the collaboration process like between the two of you?

Jeorge: I drew up a graphic representation of the pedal, including Bob’s Regen, Mix, and Delay controls, but I added the Mod (modulation) switch to simulate the wow and flutter of a vintage tape delay unit. Bob put it all together, adding the modulation circuitry to his own 600ms delay design, and the result was incredible.

Can you explain the Carbon Copy’s control setup and why you designed it that way?

Bob: We agreed to keep it simple, with just three knobs on the front of the pedal. At first, I was concerned that the modulation feature would complicate the pedal a bit too much, but the switch seemed to be a perfect solution. It allowed us to maintain the simple three-knob setup on the face of the pedal, and we put the modulation Speed and Width controls inside the unit as“set it and forget it” tweaks.

How does the Mod switch simulate an aging tape echo unit?

Bob: Engaging the Mod button places a slight pitch shifting movement on the delayed signal, which is reminiscent of tape echo wow and flutter. The internal controls are factory set to best simulate those subtle effects, but they can be adjusted for a much more pronounced and intense chorusing sound.

Jeorge: The modulation was a very important aspect of this pedal—it adds depth to the repeats and makes them sound bigger and more full. Very few delay pedals had that feature at the time.

How does it compare to past MXR delays?

Jeorge: The Carbon Copy Delay is a completely different circuit from the old big green MXR^® Analog Delay. That unit used a Reticon R5101 BBD, and it didn’t have modulation. I think it did about 450ms? It was also very noisy.

Why do you think this pedal is still the bestselling delay six years later?

Jeorge: The market was missing a delay designed according to the MXR ethos, which emphasizes great tones, ease-of-use, and rugged durability for a reasonable price. We filled that gap, and we couldn’t be happier that it’s become the “go to” analog delay pedal.

What spurred the development of the Carbon Copy Bright Delay?

Jeorge: Well, the standard Carbon Copy Delay is famous for its dark, rich warmth. There are a lot of tone guys out there, though, who wanted to hear how it would sound if it was tuned to bring out more of the high end in the repeats so they could have more than one Carbon Copy flavor. Working with Aaron Miller and the Pro Guitar Shop team, we designed the Carbon Copy Bright with those players in mind.

Bob: Pro Guitar Shop’s customer base is very much centered around that type of player—the guys who love to find just the right sound for each application—so we thought they were the perfect partner to work with on this project. We passed a few prototypes back and forth until we found the sweet spot, and it really sounds great.

How exactly is the Carbon Copy Bright Delay different from the standard Carbon Copy Delay?

Jeorge: The Bright functions exactly the same as the standard version, but it’s tuned differently. Because the higher frequencies are more pronounced, this pedal’s repeats are more defined, and the modulation shimmers a bit more. It’s a great contrast to the standard version’s darker, warmer repeats.

Bob: If you’re into tone crafting and all that good stuff, there’s definitely room for both Carbon Copy pedals on your board.
