Roland AF-60 BeeGee

Roland BeeGee 2cc1c65d8c2b

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

Earthquaker Devices Hummingbird V2

EQD Hummingbird V2 fc5f1f55af3a

It’s derived from the Vox Repeat Percussion and now updated to use the 2N6027 in place of the obsolete 2N2646. There’s also a couple other improvements from the earlier version so a new layout seemed like a good idea. … Read more

Gamers might get the reference. This came out from my wish for a simple, clean treble boost that could work from a variety of supply voltages … Read more

Reagun Overdrive 7d94ed3f0dbc

Second post for today is the Overdrive from Manfred’s trace (at FSB). This comes from the same series as it’s distortion brother (see the earlier Vesta Fire Distortion post), but the design is slightly more obscure. Still, the inverting input filter path to ground gain pot method on a non-inverting gain stage is used. However, … Read more
