Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.

Output is the master volume. Input attenuates bass and front-end gain, moving from a full, open response clockwise to a tighter, more focused response when rolled back.
02Can the Fumble be used as an always-on pedal?
Yes. It is described for always-on use, front-end preamp boost, and pedalboard tone sweetening.
03Will it add high-gain distortion?
No. It is described as a low-gain JFET clean boost, not a high-gain drive.
04What power does it need?
It requires 9V DC center-negative power and draws 5mA.
