This is the Beatsound Distortion Booster:
After doing some more digging I discovered what this magical triple-knobbed beast was all about.
It appears to be a Big Muff (kinda) with an additional footswitch/circuit that kicks on even more sustain. (So a Muff + Compressor maybe?) At least that's what I think may be going on here.
*Nerds please let me know what you think in the comments.
I did find more photos (*big thanks to all the owners of this media :) and even a video demo!
So I apologize for adding yet another pedal to your "must find or I'll literally die" list, but be assured that I too am feeling the pull of this monster.
Alright, now for your pedal porn//
Thanks for reading!
