Fulltone GT-500 FET Distortion + Booster / OD
Discrete F.E.T Hi-Gain Distortion and Overdrive Booster in ONE BOX. Think of them either as two separate pedals or as stages to be linked together for endless combinations. The Hi-Gain side has Volume and Distortion knobs with Bass, Mid, and Highs minipots. The Booster side has Volume and Overdrive knobs with Bass and Highs minipots. (These new Hi-Q sealed minipots don't break BTW.)
Hard clipped distortion (the way most pedals achieve distortion) at one point in a circuit can be cool, but stage after stage of FET (GT-500) is very real, very amp-like, has ridiculous amounts of sustain even at low volume, does the great chunky low string rhythm stuff and cleans up incredibly well when you turn down the guitar's volume. The GT500 contains 9 x FETs, 2 Mosfets and 1 x Transistor with no opamps or clipping diodes used.
