Death by Audio Sound Saw

Not quite a Fuzz Friday, but a Filter Friday I guess. Goes hand in hand with some fuzz though. The Sound Saw has two different passive filters selected by the Channel footswitch. The filters then share a 2-transistor gain recovery stage. Here's the schematic for reference. You can use a common cathode LED for the Channel switch or 2 individual LEDs if you prefer. See wiring diagram below. Laid this out for a 125B, but should be easy enough to adapt for 1590BB if you prefer. Will probably be doing a fabricated version of this in the near future as well.

Sound sample:

Hyper Fuzz regular and then the Sound Saw comes on

Clean guitar into Sound Saw changing tones

Bass Guitar into Suppa Tone Bender into Sound Saw

Bass Guitar into Big Muff then Sound Saw

Fortin 33

This one's a monster of a boost. Runs off ~36 volts, which is converted internally from a 9v supply (don't try and run it off a 12 or 18v supply or things will fry). Also make sure your electrolytic caps are rated at 50v for this one. Schematic found here. Forgot to put it in the notes, but the Out is from Volume 2.

Double Llama

Had a request for 2 Red Llamas on a single board, and my initial reaction was, "Just build two," but since there are 4 unused hex inverters that could easily be used for a second Llama, my reaction changed to, "Why not?" lol Designed to fit in a 1590BB, but might fit vertically and sideways in a 125B.

JSA MUR Fuzz

This week for Fuzz Friday here's another design from JSA. It's a Fuzz Face variant, with additional controls and an additional gain stage at the end. Should squeeze into a 1590B.

Marshall Guv'nor

Here's another layout that needed a refresh/correction. Old layout was pretty trash and had a few errors which have all be resolved. Similar to the Blues Breaker (at least in circuit topography), but with a 3-band EQ and hard clipping. Bit more gain and distortion on tap. Here's the schematic for reference. Should fit nicely in a 1590B.

EQD The Warden

This one was due for a revision/redo. Optical compression with all the knobs from our favorite pedal slingers in Akron. Will fit nicely in a 125B with top mounted jacks.
