The V2DT Double Trouble Dual Overdrive is Visual Sound's interpretation of the TS-808 with bass boost and lots more volume, times 2! Use either overdrive by itself or combine them. For each overdrive, Double Trouble includes level knobs for Drive, Tone and Volume| plus wide and sturdy stomp switches. Bass boost can be switched on or off separately for each overdrive. 1/4" jacks in and out. Everyone loves the overdrive channel in Visual Sound's Jekyll & Hyde and Route 66 pedals. Over the years, Visual Sound has had many requests to put two of these overdrives into one pedal, allowing for two different settings and the ability to use them together. Now you can have that great sound and all the advantages of V2 Series construction, plus the addition of an innovative noise reduction system, in the Double Trouble only from Visual Sound!
