The 1979 features a footswitch to bypass the tone knob, so you get ALL the bass, ALL the treble, and a HUGE helping of extra mids and volume. Perfect for slamming your amp into a ripping solo, or doom/stoner mode. But most importantly, the tone bypass has it’s own volume knob so you can set it to unity or boost! We also adjusted the taper of the original gain pot to have a more usable sweep.
This peculiar Muff uses an IC, instead of the traditional transistor set, resulting in something that’s both familiar and different at the same time. The sound is more raw and aggressive than a typical BMP. Please do not expect subtlety. This pedal does not “clean up well” with your volume knob. It doesn’t sound pretty. It’s probably not appropriate for waltzes or jazz standards. It’s not supposed to be. It smashes you in the face.
