It' the pedal you™ve been waiting for “ incredible twin distortion in a single stomp box.

With two Dr Swamps in a single pedal, you can toggle between your favorite Dr Swamp settings to deliver two brands of sweet T-Rex distortion without tweaking any knobs.

The GAIN A knob controls the amount of distortion, when using switch A.

The GAIN B knob controls the amount of distortion, when using switch B.

The TONE knob affects the top end (edge) of your signal without compromising sonic quality, allowing you to dial in the perfect tonal flavor for you taste.

The LEVEL knob sets the overall volume. In mid-position (twelve o™clock) the volume level is 1:1. When turned full over (clockwise) the input signal is boosted 15dB.

INDICATORS: The tone regulators have built in lights. They show which channel is active, A or B. To turn off the pedal, you just hit the channel that lights and the pedal is bypassed. To turn it on, just hit the channel you need to be active.

Gain1 setting gives you that magnificent Mudhoney fuzz while the Gain2 setting is more like a classic British stack with tight low end response. Volume control is unity gain in the 12 o'clock position and provides up to 15dB of boost. Great for solos with enough gain to get that comfort zone with clarity.

Twin distortion
Start out with a great chunky rhythm sound “ warm and bassy, but with a nice crisp edge. Then, when it' solo time, kick your Dr Swamp in to high gear to deliver a gorgeous, searing lead sound that™ll take your playing to new heights.

If you like a cleaner rhythm sound, then reserve the two channels of your Dr Swamp for two different lead settings “ a more restrained classic blues sound, for example, and a High Voltage rock-and-roll scream. No matter how you choose to set it up, the new Dr Swamp twin distortion will always give you more.

T-Rex tone
Dr Swamp gives you twice the distortion “ and twice the legendary T-Rex tone. Designed to deliver the rich warmth that T-Rex felt was missing from other pedals on the market; Dr Swamp has become a standard-setter for tone in distortion.

NEED this pedal

Comments about T-Rex Engineering Dr. Swamp Double Distortion Pedal:

I need two overdrive sounds in addition to the clean sound. I was using two independent overdrive pedals. But, having two pedals is not easy to use, since they have two independent on/off switches. I needed two steps from one tone to another tone among the three sounds.The two switches of this pedal are totally different. I can change from one sound to another sound by just one step in all patterns. So, I NEED this kind of pedal. I am not over-expressing. And, I guess there are many users like me. The sound is rustling, not muddy. I think I should prefer this blue one to the brown one from the same vendor, since I like bluesy sounds. I set the drive knobs to 10 o'clock and 2 o'clock. My picking is very soft. I guess less drive setting might be better for usual pickers.Only downside is that I need to remove the rubber feet to put the pedal on a pedal board. I guess many users have to do this.

my Overdrive and Distortion

Comments about T-Rex Engineering Dr. Swamp Double Distortion Pedal:

Why I gave it so good:1) you basically get two channels. You can program one channel to get nice blues backing sounds and the other to get screaming lead2) It does not fuzz, get hidious background noise or will take away your tone. (online and offline)3) the sound is simply amazing. You can easily go from Heavy metal (using an already distorted amp or using it with another od or distortion) to nice breakup blues sounds.simply a no-brainer: you can get two distortion/overdrive sounds at the price of one and the sounds are amazing. Use it on an epiphone junior valve head and you will be amazed!

      Comments about T-Rex Engineering Dr. Swamp Double Distortion Pedal:

      I will admit that when I ordered this pedal I didn't really know what to expect. When I got it, I popped in a new 9 volt battery and played around with the settings to get myself a blues-rock tone and a hard rock tone. The settings are simple: volume level, gain, and tone control. Both channels are identical and can be set from subtle volume boost to heavy rock. I use this through my AC30's top boost channel and the sound I get is what I've always wanted my guitar to sound like. This thing puts a smile on my face and I couldn't be happier.
