Here's a popular JHS pedal that emulates old Supro/Valco amps: the Superbolt. It has a remarkable similarity to the Run Off Groove Supreaux and Supreaux Deux. It seems to be a slightly modded Supreaux, with the high/low switch and 18 volt supply of the Supreaux Deux. A charge pump is also added so the pedal can run off a typical 9v supply. You can use an ICL7660 or MAX1044 in place of the LT1054 (though, if you use the MAX1044, be sure to ground pin 5). This one's laid out for on board pots…
Lovepedal Delux 60 Mosfet Boost
Hadn't done a boost pedal in a while and hadn't done a Lovepedal pedal in a while either, so I'm killing 2 birds with one stone. The Delux 60 uses a Mosfet gain stage set to give clean boost or to push a tube amp into break up. It's simple but effective. This'll fit into a 1590a pretty easily too.
MXR Commande Sustain
Here's one from MXR you probably haven't heard of before. It was apart of their Commande line of plastic boxed effects from the late 80s. They aren't highly regarded because of the plastic, but the circuits were pretty well designed. The circuit in question today is a better design than the DynaComp, offering less distortion and more sustain. It does have a little less compression range than the DynaComp, but also less noise. (And really, who needs that much squish? haha) Couldn't find a…
Dunlop Band of Gypsys Fuzz Face
Here's the Band of Gypsys Fuzz Face from Dunlop for Fuzz Friday. Despite being called a Fuzz Face, the actual circuitry of the Band of Gypsys version isn't even close to the original Fuzz Face. It's pretty close to an Octavia without the transformer. Here's the schematic for reference.
Fairfield Circuitry Barbershop Overdrive
This one was a request. Two pots onboard and one offboard. The Barbershop Overdrive is a transparent overdrive/booster with medium gain. It has the expected Volume and Drive controls, but also has a Sag control which alters the voltage the pedal is running at. This can change the color and compression of the tone. UPDATE: I did a little research, and found out Q4 is just a fancy way of doing polarity protection and can be omitted if you want. Here's a layout without it.
