DESCRIPTION: The FEZ pedal is a drive box meant to ramp up your tube spring reverb. I built it for my F-Bomb spring tank (a clone of a 6G15 vintage fender tube spring reverb unit) so I could have that huge woody grind of a tank into an old large amp at more manageable levels. Dirty surf if you will, perhaps an overdrive meant for reverb. platform of circuit is based off a DOD 250 greybox overdrive/preamp. metal can opamp and premium components
