Heavy Darling Fuzz

Found this one over on DIYSB and thought it'd be a good Fuzz Friday layout. It was designed by Dragonfly for the old FX-X contests. Here's what he had to say about it:

The Heavy Darling is a SIMPLE fuzztone that cleans up great, has old school character, and good sustain...pretty much ANYONE who can solder should be able to build this one. It uses a MPSA13 Darlington transistor in the 1st stage that pushes the 2N3904 into full saturation. The 220k resistor limits the amount of saturation, and you could certainly experiment with values here. A pot could also be used to give some variable gain, and you could even set up the pot in a similar manner to the Orpheum, Fuzzrite, and Shin-Ei style fuzzes.

Montezuma Fuzz

Here's another Dragonfly design. This one is basically two tweaked Electra Distortion circuits stacked back to back. Here's a sound sample. Should fit pretty easily in a 1590a.

Golden Dragon Overdrive

Here's a simple overdrive circuit adapted from the National Semiconductor "Ultra High Gain Audio Amplifier" and Jack Orman's "Minibooster" by Andrew Carrell (Dragonfly). It should easily fit in a 1590a.

Simple Clipper Distortion

I found this layout going through an old folder on my computer. Pretty simple IC-based dirt circuit and will fit in 1590a. Here's a sound sample.

JFET Boost

Here's a quicky. It's an old Dragonfly design and was my first perf build.
