The T-Rex Dr.Swamp is a double distortion pedal. It has that rich vintage sound, T-Rex is known for. In addition to the warm crunchy sound, this pedal gives a lot of steady bottom. The Dr. Swamp was developed in response to a number of requests for a great sounding distortion unit like the , but one that would allow the player to switch from one preset gain setting to another by simply stepping on a footswitch. T-Rex decided to go another step and voice the Gain2 setting on the Dr. Swamp more like a classic "British Stack" with a tight low end response, rather than a fuzz like the Mudhoney (where the boost switch engages a fuzz setting). The volume control is unity gain in the 12 o'clock position and provides up to 15 dB boost in the maximum position.

Approximate Dimensions: 4" wide x 4.75" deep x 1.5" high

T-Rex pedals are handcrafted in Denmark.
