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 the years, both germanium and silicon, so socket and experiment. Easy fit in a 1590B.
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 goes the more hybrid route, giving you the option for TH or SMD caps (except for electrolytic caps). The opamp remains TH so the LM308 can still be used.
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 amplifiers, an opamp stage, hard clipping, and a BMP-style tone stack. Here's the schematic for reference. Easy fit in a 1590B.

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." More info here.
