What's your favorite 2-knob circuit?

Title says it all.

As for me, the best device is just a 2-knob one:
1. The first knob is ON/OFF
2. The second knob is VOLUME
NO MORE KNOBS !

As of last Friday, it's my freshly-built Heladito-02 (Small Clone clone from tonepad) with my bass going through it.

For now, my mini PWM Fuzz I made...Love the Lo-Fi/Atari/8-bit Fuzz sounds it produces...

Sugar Baby trem.

Nice.

It would probably be a circuit that originally only comes with one knob, but I decided to add another.

don't make me choose between:

Mk2 Tonebender
CE-2
Fuzz Face

edit: While fine choices, none of them are the SuperFuzz.

how bout one that came with 8 knobs and you hard wire the other 6 to your favorite positions...

Tonebender MKII.

*So* much gain - and more top-end than a stock Fuzz face.

Worth doing the Ge Transistor auditioning for...
