Had a couple questions about stompbox use with line level, so I drew up this. This allows you to drop the line level signal down to instrument level, send it out to whichever stompboxes you want to use, then back and amplified back up to line level. Schematic and discussion here. Made two versions, one that could be run off typical +9v pedal power, and another for bi-polar 12v supply used in Eurorack synths, so you can build it either in pedal form or Eurorack module form.
Turns out the Southland is pretty much the same circuit as the Lightspeed, but with some hard clipping diodes thrown in the middle (and a couple value tweaks). Figured I'd make a new layout with space for the diodes. This layout uses the same drill template as the Lightspeed.
Happy Fuzz Friday, everyone! Here's a cool take on the IC Big Muff by JuanSolo and Grind Customs. It's essentially the '78 IC Big Muff with the tone bypass switch with the tone stack from the Ultrastoner. Should be able to squeeze it into a 1590B.
Here's a transistor based overdrive I came across on FSB. Demos sound interesting, so give it ago. Easy fit in a 1590B.
Here's a popular drive box from Greer Amps. It's essentially a Distortion +/DOD 250 but with a modified gain control, LED clipping and a treble cut pot. Should be an easy fit in a 1590B.
Here's a really great sounding overdrive from Hudson Electronics. The Sidecar is loosely based on the Tube Screamer with a 2-band Baxendall EQ and some interesting soft clipping. It uses a PNP germanium as a diode along side an LED and a 1N4148 in an asymmetrical configuration. I've got a fabricated version available in the store as well if you prefer and the schematic is over there in the build doc.
Happy Fuzz Friday everyone! This one recently got traced on the Aion blog (so go check out the full write up over there for more info and schematics). The Karma Suture is based on the Harmonic Percolator and has come in both germanium and silicon versions. The difference between the two are just a couple value changes, so you can build either version on the same board. Value differences are outlined below.
