All the vintage amp tone fun of a 60's Supro in a 1590B.
Based on a boutique pedal which is itself based on the excellent RunOffGroove Supreaux, but with a couple of tweaks. This version offers a built-in charge pump to run the circuit at 18V instead of 9V, giving much more headroom. A Hi/Lo toggle switch emulates the Hi/Lo inputs of the amp, so giving you more dirt or more clean headroom on tap.
Overall, this is a fantastic open-sounding drive with a huge range of gain and tone control. Big thumbs-up to RunOffGroove. No mention of them on the 'boutique' site... shame on those people.
Board-mounted pots and switch make this a quick, simple build. Latest version has pads for through-hole or SMT FETs, since through-hole are getting harder to come by.
Please choose your knobs to suit the pot shaft you select in the options. The vertical-mount pots have round shafts, so require knobs that fit with a grub/set screw.
Partial kit: PCB, all board-mounted components, pots.
Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.
Enclosure (pre-drilled) is only available with full kits, and will not take a battery. Knobs are not included.
Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.
PCB size: 50 x 40mm
Knobs required: 3
Direct-Connect compatible (4-way)
NOTE: You'll need a mutlimeter to bias the FETs in this circuit.
