Run Off Groove Supreaux Deux
Often imitated by boutique builders, the ROG Supreaux Deux overdrive is an old Supro 16T in pedal form. The Deux is the 2nd go at this circuit and offers several improvements over the original design. It runs off 18v, so I’ve added an onboard charge pump converting +9v to just under +18v. You can use … Read more
Electro Harmonix ’77 OpAmp Big Muff
In the late 70s, Mike Matthews and EHX took the Big Muff on a detour from the traditional 4 transistor circuit in favor an IC-based circuit. It sounds very similar to the traditional Muffs, with the tone control being a little more flat than the traditional mid scoop. The circuit uses two favorite opamps from … Read more
EarthQuaker Devices Monarch
This is a great sounding Orange amp emulator by EQD. The EQ controls allow you to boost those frequencies instead of just rolling them off. Lots of big burly Orange tone in this FET based circuit. I’ve laid it out so you can board-mount all 4 pots from the solder-side of the board using right … Read more
Alembic Stratoblaster
The Stratoblaster was originally built as an onboard preamp that could be mounted on a Strat in place of the normal output jack canoe. The gain was adjusted by a trim pot (so no external knob), but the circuit provided 3-14 dB of clean boost. It’s a great simple circuit and can fit in a … Read more
