Way Huge Tone Leper

This is a rare one from the early 90s from Way Huge and is based on the Craig Anderton Frequency Booster. Stock it gives a mid range boost (800Hz), but that frequency can be altered by swapping the 2, 22nF caps:

220nF - 90Hz (lows)
100nF - 200Hz (low mids)
10nF - 2kHz (mids)
4.7nF - 4kHz (upper mids)

Bass Filter Pedal

Here's a cool little bass filter pedal designed by bleepboxes. Really low parts count should make for a pretty quick build. Original info here. Might be a good idea to put the 4.7n cap on a switch with a 2.2n for more tonal variation.

OKKO Dominator

Here's a big one, and just so happens to be the 700th layout on the blog 😎—the OKKO Dominator distortion. It's a couple of JFETs pushing an opamp with active EQ, with a charge pump. Originals use a switch to select the range of the mids control, but it's easy to swap out for a pot. Schematic can be found here on FSB for reference. Easy fit in a 1590BB.

Spaceman Titan II

Happy Fuzz Friday! Here's the Spaceman Effects Titan II fuzz, traced by Dino (Digi2T). I simplified the polarity protection, removing the BS250 in place of a simpler 1N5817 diode. Transistors need to be pretty low gain—under 200 hFE. Should be an easy fit for a 1590B.

Friedman Golden Pearl

Here's a good sounding lower gain overdrive from Friedman. Several options with this circuit with clipping and tone options on toggle switches. Fairly transparent, as they say.

Discrete Llama

Happy New Year, everyone!

Some audiophiles have really gotten into preamps that use discrete opamp—basically using and bunch of individual transistors that make up the internal circuit in an IC. This trend has also made it's way into the guitar world as well. One of the simpler circuits I've seen you can do this with is the Way Huge Red Llama. Inside the CD4049 in your typical Red Llama is essentially a bunch of MOSFETs. John from Electronic Audio Experiments and Alec from Mask Audio Electronics worked on this and Alec sent me the schematic to share with all of you.

Cornish P2 (probably)

For Fuzz Friday here's what most people think is the Cornish P2. It's a slightly modified Ram's Head Big Muff with flat mids and the Cornish buffer up front. If you want to use the Cornish bypass like the original check out the Cornish G2 layout for the bypass board.

Also, this will be the last layout of the year. Taking some time to rest up over the holidays. See you in the New Year and Happy Holidays everyone!
