The Finch Electronics Plexicle is an Op-Amp based distortion circuit modeled after a classic 59 Plexi Amp. With the Gain and tone knobs, you can get a wide range of British Style tones. With the Gain between 7 and 12, you get that classic plexi tone that everyone searches for. Once you get past noon, the pedal emulates the tone of a JCM800. The tone knob can produce tones that range from super dark, to super bright, and everywhere in between. If you are looking for some delicious, sweet, tones – look no further than the Finch Electronics Plexicle.
