Passive volume box to put in the FX loop of your amp, or in front of it. Add a volume, or master volume to an amp. Completely passive parts so no power required.
100kA potentiometer, 1590A enclosure.
If you pick a random color, you'll get randomly something that we have in stock.
Disclaimer : This ain't a power attenuator, installing this device between your amp Speaker Out and a Cab will surely destroy something.
