My another monster: personal Sound Lab.
Ugly but lovely:

There are 5 devices in one box:
1) Fet Booster (Fetzer Valve de Lux R.O.G.)
2) MC33182D rail-to-rail dist followed Schottky pair
3) LPF 8-th order with cut-off 3 kHz
4) LPF 8-th order with cut-off 4,5 kHz
5) Peaker 2,8...4,2 kHz
All are true bypassed.
Lot of switches - lot of sounds!

Rat's nest? Yes, that's true...
