HexeFX Night Train OD
Came across this circuit and thought it was interesting. It’s similar to the Tube Sound OD with added input and output buffers, plus gain and tone controls. Info, schematic and sound clip available here.

Fulltone Mas Malo
For Fuzz Friday, here’s Fulltone’s take on the Big Muff. The main differences over a regular BMP is the input and output stages. The input stage has it’s own gain control and the output stage is a JFET-based gain circuit. Also the volume control has been moved immediately after the tone stack, with the output … Read more
Earthquaker Devices Tentacle
Had several requests for the Tentacle, but it’s just more or less a Dan Armstrong Green Ringer clone. But I had the idea of making a Green Ringer layout with the bypass footswitch board-mounted so we’ll just call this layout the Tentacle. Should fit easily in a 1590A. If you’d rather a fabricated PCB to … Read more
Budda Chakra Compressor
Here’s an optical compressor I came across on FSB and hadn’t seen a layout of it before. There’s some question as to whether the schematic is accurate on FSB, so build with care. The original uses a rectifier array component, but I’ve broken that down into 4 discrete diodes (1N4148, 1N4001, etc.) since I figure … Read more
Jon Patton Cruz Drive
Here’s an transistor-ization of the Butler Tube Driver by Jon Patton. Here’s what he had to say about it: I replaced the op amp buffer + inverting drive stage with a MOSFET booster, and replaced the tube stages with with FETs in the normal manner. Note that the design inverts phase, which the original did, … Read more
VFE Fuzz Duo
Happy Fuzz Friday! Here’s a pretty cool Fuzz Face variant from an equally cool builder, VFE. Both transistors are switchable between silicon and germanium, and it’s got a few other cool tweaks too. Schematic here for reference.
Ibanez NB-10 Noise Buster
Had a recent request for this one and thought it’d be a nice break from overdrives. Part of the Ibanez 10-series, it’s a noise gate that utilizes the LM1894 noise control chip. You can still get the chip off eBay and the SMD version is available from Arrow, Mouser, etc. You can wire it for … Read more
DOD 210 FET Preamp
Got a little simple boost/preamp for your Thursday. Should be a pretty easy fit in a 1590A. J113 alternatives would be J201, 2N5457, and probably a couple other JFETs that are obsolete. 😑
Apocalypse Audio Four Horsemen
Stumbled across this circuit a little while back and thought it would be a nice change from most of the opamp-based overdrives out there. Should fit nicely in a 1590B.
EarthQuaker Devices Life Pedal
For Fuzz Friday here’s the coolest Green Ringer + Rat pedal around! (To be fair, it’s an awesome combo) The Green Ringer is on a JFET blend and the Rat section is pretty standard. There’s also a fairly generic MOSFET boost on board as well, similar to a SHO or Black Eye. This should all … Read more
