Here's the electrical profile of the upcoming Mudlark, with intent of establishing a tier between the Tetanus Booster and the Dirty Doper:

The idea here, in a nut shell, is a capable preamp section (similar to the TB, but a different circuit) feeding a classic Baxandall tone stack (with reversed overlapping tapers, so as the bass goes up treble is cut and vice versa) and a FUZZ section that are order reversible, followed by another gain recovery section. So, three knobs (GAIN, TONE, VOLUME) and one toggle (FUZZ/TONE order) plus the footswitch in standard configuration.
Expected release around the turn of the year.
