Yeah, the Foxey Lady! I have one…it's a PC board v1 Big Muff offered by Guild back in the day. Very mid-scooped, which gives the impression of it not being as gainy overall as it is. (This is why David G. goosed (or followed) his with a Boss EQ to bump up the mids and overall volume a little.) I like to run mine into a Tube Screamer or an Archer Ikon (a Klone that excels at clean sounds) to tame the bass and kick up the mids.
