J. Rockett Boing Reverb
Got a request for this one and we can always do with more reverb. It's a simple one-knob BTDR-2 based circuit and should fit easily in a 1590B. Reverb brick and pot is populated on the solder side....

Here's the Mocker. It's a recreation of the on-board fuzz from the Vox UL730, used by the Beatles on Revolver and a bit on Sgt. Peppers. It's fairly simple with most of the mojo coming from the OA200...

Happy Holidays, everyone. This one seemed like it needed laying out before the year came to a close, so here's the new EXH/JHS colab, the Big Muff 2. It's an op amp based Big Muff that's not like the...

Happy Fuzz Friday! Been meaning to redo this one for a while with board mounted pots. A buddy of mine was reminiscing about a Sunface he used to own and wish he still had, so I built this with some...

There's no getting around it, through hole components have long been on the way out and being replaced by SMD. I've had several clients I do board design work for either going full SMD or at least a...

Happy Fuzz Friday, all. Somehow in 10 years of laying out fuzzes, I've never done this one. Here's the Roland (pre-Boss) AF-60 BeeGee fuzz. Originals use semiconductors you probably don't have in your...

I traced this one a while back. It's the same delay circuit as the Disaster Transport Jr but with modulation added. It fits nicely in a 1590BB like the original. Schematic here. If you'd rather a...

Here's another old layout redone for all you Jonny Greenwood fans. I think the old layout was based on an old and incorrect schematic (here's the schematic used for this layout), but this one should...

For Fuzz Friday here's the Roger Mayer Axis Fuzz redone with board mounted pots. Schematic for reference. Didn't make a drill template for this one, but the pots are 1.2" apart and should be an east...

I'm a big fan of Brian's, aka Aleph Null's, circuit designs he's been kind enough to share over on the MadBean forum. Here's one of his latest offerings, the Special Sauce. In his own words, "It's a...

Stumbled across this one I though would be a quick Fuzz Friday layout. It's a modified Zonk 2 with silicon transistors. Originals use NOS 2N3416, but other low hFe (150-200) BJTs should work just fine...

Did this one quite a while ago, but wanted to redo some of the old layouts with board mounted pots. The schematic online has the topology correct but the 100nF caps are 47nF from the gut shots I've...

Happy Fuzz Friday! Here's a Univox Super Fuzz derived circuit from Earthquaker. Should squeeze into a 1590B just fine. Here's the schematic for reference:

Here's the new boost from Matt Hoopes. Cornish buffer up front, so like the DRV, not a true bypass effect unless you want to wire it that way. Signal is then amplified by half of a 1458 op amp, and...

Here's one of Greer's latest offerings. Seems like a simplified OCD circuit with some value changes and different clipping diodes. Schematic for reference. Easy fit in a 1590B.

Happy Fuzz Friday, folks! Stumbled across this one recently and looked cool. It's basically 2 SHOs in series pushing a Green Ringer. Schematic for reference. Should fit nicely in a 1590B. I've also a...

Here's a fairly unique OD from the mid-nineties and the Polish pedal manufacture Exar Electronix. It's a soft clipping drive based around a simple discrete opamp topography. Originals have J113 JFETs,...

This one's gotten a fair amount of hype over the years. It's essentially a Timmy without the bass control and a few different values. The IC and clipping diodes haven't been confirmed, other than 2...

Happy Fuzz Friday everyone! You probably didn't miss this collaboration between Josh Scott and Mike Matthews, and because of the old school style of the big box version, it wasn't to hard to trace....

Yes, Modulation Monday is back with the Ross Phaser. It's not for the feint of heart, but doesn't require any JFETs, matched or otherwise. Instead it uses OTAs with 3, LM13700N (one for the LFO, two...
