Welcome. You are looking at a great piece.
This is the Electro Harmonix Signal Pad Attenuator Pedal.
The EHX Signal Pad guitar pedal is a passive attenuator that allows you to instantly switch to a different preset volume.
Leave amp volumes set for overdrive and use the Signal Pad to lower your level for a clean tone, just like rolling back your guitars volume pot but with pinpoint accuracy each and every time.
And the true bypass switching keeps signal path pure when not in use.
A uniquely useful pedal that will find a home in many, many pedalboards.
We are an authorized Electro Harmonix dealer.
