This is my "big box" version of the now famous and very sought after “Op Amp” version of this great pedal. The original was made simultaniously with the "standard" version 3 but used op amps instead of transistors. It is close in tone, still with scooped mids but a much bigger, “rounder” bottom end. This version had the tone stack bypass push/pull switch on the VOLUME knob but I run it as a normal (scooped) or flat response while still keeping the tone control intact for more options.

This is the version that is famous for it’s use by Billy in Smashing Pumkins but I prefer to think of it as the first three Dinosaur Jr albums. It's a big, fat, thick wall of sound BM.

These are full sounding fuzz with lots of output and the option of the flat mids switch while keeping the tone control gives it a range from big and thick to big and thin. Check my blog for more details.
