Instant Mojo for Any Guitar Tone

Calling the Dunlop EP101 Echoplex Preamp a preamp/gain boost pedal doesn't do it justice. Based on the legendary Echoplex EP-3 used by icons like Eddie Van Halen and Eric Johnson, the EP101 gives you the sweetened sound of the EP-3's preamp stage. You get a vibrant boost for most of the gain range, and Sweetwater guitarists love the warm overdrive you get when you really crank the gain. We know that sometimes your guitar tone could use a little extra something that traditional tone-shaping tools can't provide, and for that we can highly recommend the Dunlop EP101 Echoplex Preamp.

Dunlop EP101 Echoplex Preamp Pedal Features at a Glance:
  • Preamp and gain boost pedal for electric guitar

EP101 adds the missing ingredient

I added this pedal to my board and I am completely blown away by the difference it makes. I added t to a board that runs a DynaComp compressor, Boss FBM-1 Fender '59 Bassman, Voodoo Labs Tremolo and HOF reverb the EP101 is first in the chain. The FBM-1 input uses the "bright" in and the level is unity, gain just a push and the presence boosted - and what a difference adding the EP101 makes - the EP101 adds just a little extra that makes the mids and highs really sparkle overall. Truly hard to describe, but the tone just shines with the EP101.

Great Addition

I bought this pedal because I have been reading a lot about the Echoplex lately and don't have a grand laying around to check out an original. My current rig is an Epi 60's Tribute Plus through an Orange CR60. Some days I love my tone, some days not so much. I think your mood has a bigger effect on your tone then most people realize. The addition of the Echoplex has added more punch, definition,and clarity to my set-up. Running it around 7 seems to be the sweet spot for me. It also plays real nice with my chorus and delay. I would definitely recommend giving it a try if you are looking to add a little shape to your sound.

Loving it a tone sweetener

I love this pedal. I did a fair amount of reading before buying it, since there are a handful of other options that attempt to replicate the Echoplex preamp magic. I chose the Dunlop EP101 because Dunlop owns the Echoplex product rights, and this pedal is an exact reproduction of the Echoplex preamp.So what does it do, really? It sweetens my tone by injecting an unique mid-boost that works really well with my playing style and just gives it a nice extra "juiciness" that I like a lot. It is the very 1st pedal in my signal chain (as recommended!). To my ears, it is subtle but significant, and depends on how I set it. I keep the EP101 gain knob at about 2 o'clock, and the pedal is always on. For me, it's a set-and-forget pedal for tone-sweetening.I'm also a fan of the BOSS FB-2 for its tone-shaping ("contour" knob) capability, and put it as my 2nd pedal in my signal path immediately after the EP101. The FB2 is also aways on. Similar to how I use the EP101, I have the FB2 dialed in to a subtle but noticeable slight mid-boost, to add a little more "juiciness" to my overall sound. EP101 -> FB2 -> everything else. Excellent combo for me.If you're a tone monkey like me, and you've been searching for something to make your signal shine a little sweeter, I recommend this pedal. It does exactly what I expected, and it does deliver. I can understand why other now-famous guitarists like how the Echoplex preamp livens their sound, because it does the trick for me!


I'm using it as a boost. Not for volume ; just to give me that "little bit more" for certain songs and solos. Works perfectly , sounds sweet!

Let down

To be fair I bought this on a whim- I liked the idea of having one of these on my pedal board but to be honest, I couldn't find a need for it. I used this in conjunction with an 808 and a Fulltone '70 fuzz and to be quite honest it didn't add much of anything to either or.I messed around for about two weeks placing it in different spots on my board. No joy. I'll probably be sending this one back. No fault of Sweetwater's, just not digging it,
