Ramble Effects at Haar Guitars

Marvel Drive’s JFET based design is different than most distortion pedals. JFETs are a type of transistor which behaves very similarly to vacuum tubes. In fact, part of Marvel Drive’s circuit is identical to that of a plexi amplifier, substituting JFETs for vacuum tubes.
Your search for the perfect plexi pedal is over! Marvel Drive delivers the KRRR-ANG, crunch, and growl that has defined rock tones from the 1960’s through today. It uses JFET transistors to simulate tube gain stages, creating the give-and-take response that guitar players love.
