Great for modeling Guitar and Bass amps. I used this for years as DI into small PA for practice here at the house.

fyi, this pedal has two minor issues:
1. missing one of the top adjustment knobs.
2. the bank up foot pedal occasionally does not respond, so it has to be pressed once or twice to get it go to the next bank up.
$80 shipped lower 48 states.
Includes the power supply as well.
