T-Rex Engineering Dr Swamp
The T-Rex Engineering Dr. Swamp is an overdrive pedal that has 2 channels so you can set two different types of distortion/overdrive and toggled between the two. The pedal is an analog pedal and has a 1/4 inch input and output. The effect is not rackable as it is a stomp box.


The set up of the pedal is very easy. There are four knobs - 2 for each channel. It is really easy to get a good overdrive tone out of this pedal - just simply adjust tone or level and gain to set how much or how little distortion you would like. I've never used the manual because I haven't had a use for it.


The overdrive produced from this pedal is rich and full in tone. I have only used this pedal with guitar - usually a Fender Stratocaster into a Twin Reverb, and it adds a rich overdrive tone to my sound. Both of the channels sound good on this, both while using a small amount of the effect and while cracking it, depending on what you are going for. I would imagine that this pedal would sound good with other instruments too, but I've never had a need to try it out with anything other than a guitar.


I have been using the T Rex Dr Swamp for six months and I'm really glad I got one of these. I used to own an MXR Double Shot Distortion, which also has a 2 channels, and this pedal sounds way better - both a rich tone and more authentic sounding. I've come to love the pedals T Rex makes as they sound great and are built well. While this pedal is a bit higher priced than your average pedal, to me it is worth it because I know I am getting a product that will last for a while and has a sound that adds something to my tone.

T-Rex Engineering Dr Swamp
Very easy to use, I have not found better: 2 switches - 2 volumes - 2 wins - two tones - one light works!
Possibility of power transformer but with good holding power batteries anyway (I've seen worse!).
Case size proportionally with good content but a little larger compared to normal pedal boxes but fits nicely in a rack foot pedal.
Front clear, easy adjustments.


Configuration very simple, no need for manual, it is written on!
I do my personal settings left side for a rhythmic energetic, clear way overdrive and right side then I slightly increases the gain and volume to jump solo with the necessary fishing.
When changing side there's a press another switch and if that is immediately operational without re press the first left off, and vice to it
I personally use this and in fact I think it is one that suits him best.
In reality it is just the same two pedals in one housing.


Again I have not found better in terms of distortion pedal, because I tried everything with Strato not easy to find a distortion that makes off, then it's all good and straight. With this Lespaul have a mere formality.
You can get that distortion sound that approximates overdrives, net and detached.
on the other hand, if you want a nice big thick sound, vintage or otherwise, no problem it sends big!
But cons for heavy metal I think you look elsewhere, this says it was not just what I research.
Marshall MG50DFX on and on my outdated! Ross 15 watt it sounds great.
This is a pedal that has a good sound and very little grain of breath too.


I use it for 1 year and I am delighted she has eliminated many problems and made me do the economy to buy more pedals.
Being a fan of pedals already hyper brands known I wanted to try and I can tell you that the test is processed I do séparerais EVER!!
on the other hand I think what's a little too expensive but ... when you're happy!
A try at all costs!

T-Rex Engineering Dr Swamp
Double overdrive / distortion. Each with Flight / tone.gain. 2 switches activation: press the first deactivates the second and vice versa. To be more clear not possible to put 2 "pedals" series.


Well, nothing could be simpler vol / tone / gain: no need manual to understand what button does what ...


My main gear: a small (PRS CE22) or a Gibson melody maker in a fender tube (Prosonic).
My gear lo-fi: The Paul Paul Beusher 80's Strat Jim Harley changed that I do not know why sounds monstrous Strat Squier Satin Trans (its very 50's) and shovels which I dare not mention the name here (but guarantees lo-fi)
The sound of this pedal is very broad: it ranges from small good overdrive distortion well muscled. (By point against metal with it)
Personally, I spend a lot of my time to dub from Radiohead, the Clash, the dEUS, the Danko Jones, by way of Portishead, the Sherriff Laetitia, etc..
By focusing on the settings, it is possible to approach a lot of these artists. It sounds as good with double than with simple blues rock big task, it swallows everything with uncanny accuracy. The sound is always clear and all the subtleties of play even agree with the gain pushed well, especially as it responded very well to variation of attack strings. With it, no problem to break into the mix!


As you say, a few months after purchase I sold all my distortion (Jacques FuseBlower, Overdrive home-made clone of the TS9, Boss HM2 japan modified Boss MT2 ..) Now I no longer have that it in my floorboard whether in rehearsal or concert.
The sound is simply fantastic and 98.4% of that on which amp I plugged: Fender FM212, Marshall TSL, 65Watts transistor Fender, Peavey Bandit 112 and even an old DeanMarkley 2x40W, and even scratch my lo -fi, there is always a way to find a sound that the "serious matter."
This is not far from 3 years and I have NEVER, EVER hear you, I do not resell this pedal!
