Based on the EH Signal PAD
The VOL Attenuator is a passive attenuator that allows you to instantly switch to a different preset volume.
It's like your guitar's volume knob, with a fully-passive and color-free circuit.
Leave your amp's volume set high for overdrive, and use the VOL Attenuator to lower your level for a clean sound --
then switch it off to kick in your amp's natural overdrive. You can also experiment with the Signal Pad anywhere in your effects chain --
you'll bring out new tonal combinations from your favorite old pedals.
