Built with a super small design that can easily fit on just about any pedalboard, a single knob for attenuation, and impedance optimization for those with pedal chains that stretch from coast to coast, the JHS Little Black Amp Box Passive Attenuator that'll make you wonder how you got along for so long without using it. A perfect buffer to throw into the mix, this pedal, as the name suggests, is also ideal for getting cranked tube tone without the volume for bedroom practice.
