Used JHS Pedals Little Black Amp Box Pedal

This used JHS Pedals Little Black Amp Box is a simple, studio-ready solution for taming amp volume without changing your tone. In good condition, it works as a passive master volume you place in your amp’s effects loop, letting you push your preamp harder while keeping overall loudness under control. Features a single Volume knob, rugged compact enclosure, and standard 1/4" input/output connections—no power required.
