Sunn Buzz SB-1G

Saw this one over on the Tagboard blog and thought I'd give it a go for Fuzz Friday. It's a silicon variation of the Maestro FZ-1. Originals use a single AA battery (1.5v), so I've included 2 voltage diving resistors to drop the the normal 9v supply down to 1.5v. (The yellow trace in the PCB side indicates the 1.5v rail.) Originals used 2N2923 transistors, but I would imagine other low gain transistors will work (hFE range on the 2923 is 90-180). Just mind the BCE pinout. Here's the schematic for reference.

Lovepedal Hi Volt

Today we've got the Lovepedal Hi Volt. A wide variety of tones on tap with this one. It's a cascaded JFET gain stage into an active EQ section, all powered by a 16v charge pump. Laid this out with on board pots and will fit in a 125B with top mounted jacks. Here's the schematic for reference.

Hjärt Müller Bass Drive

Here's an overdrive for my fellow bass thumpers. Fairly simple opamp-based drive section with soft clipping pushing a Big Muff tone stack. Should be an easy fit for a 1590B with board mounted pots. Here's the schematic for reference.

Way Huge Swollen Pickle Mk 2

For Fuzz Friday here's the newer and highly tweak-able Swollen Pickle from Way Huge. Like the Mk 1, originals use a MPQ3904 transistor array instead of individual transistors. Couldn't make that work this time around, so just stick with individual 2N3904s. Originals also have 2 of the controls internally, but what's the fun in that? All 7 pots are for external mounting and the whole thing will fit in a 1590BB with top mounted jacks fairly easily. Here's the schematic for reference. You'll notice a few values are a 10th of typical values found in a Big Muff (indicated by an * in the layout below). Not sure if it's a typo on the schematic or just the way Way Huge did it this time around. YMMV

Lovepedal Champ

Been a while since I've laid out an Electra and I came across the Champ schematic on FSB, so here you go. Should fit with a board mounted pot in a 1590A.

Barber Direct Drive

You asked for it, so here it is: the Barber Direct Drive. This layout follows the new compact version with 2 toggles–one for harmonics, the other for gain. The circuit itself is very similar to the original Tone Pump circuit with a few modifications. Should fit nicely in a 1590B.

CultureJam NoMoJo Fuzz

This was a originally an SMD 2-in-1 board CultureJam put out. On one side was a Fuzz Face and the other this Tone Bender. So I figured they'd be good Fuzz Friday layouts. They're not on the same board, but either one should fit in a 1590A.
