Big Joe B-602 Volume Pedal

They say:

The Big Joe B-602 Volume guitar effects pedal is a uniquely-buffered active design volume pedal featuring true bypass. A three-way switch lets you choose between three operation modes: the normal classic buffered volume mode, a -12db cut mode that gives you finer volume control, or a customizable Program mode that lets you dial in the precise dB parameters you want, from 6db to 18db of gain and -6bd to max signal off cut. The Big Joe B-602 Volume can handle both high and low impedance signal loads.
