Tools, Tones and Toys for Guitarists
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. Schematic for reference.
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 clipping diodes. Socket and experiment as I’ve heard 1N4148s and 1N4001s sound good. The transistors are low … Read more
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 typical ICBM, but uses 2, 4558s in 3 soft clipping configurations into a BMP tone stack. Schematic … Read more
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 OC71s for his 40th b-day. AnalogMan has used loads of different transistors in these over … Read more
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 hybrid with SMD for resistors and a few other components, and TH for caps. This RAT layout … Read more
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 parts stash, but nothing in mojo territory, so modern equivalents will work just as well. Fairly simple circuit with a couple transistor … Read more
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 smaller footprint I have fabricated boards for a 125B in the store.
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 be right and a much easier fit in an enclosure than the old one.
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 fit in a 1590B.
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 short delay with envelop control pitch bending. This makes for unique chorus, doubling, slap back, and vibrato effects.” … Read more
