Harmonic Percolator Double Take - Albini Mod!

Steggo's new Harmonic Peolorosaurus board will not only build the "standard" version of the Harmonic Percolator, but the Albini modified version as well. I went ahead and built both versions of the circuit. This build report is therefore essentially and addendum to the previous one as there are only a few component changes.

Steggo's Take on the Harmonic Percolator!

One of the first pedals I built was AionFX's Particle - a modified version of the vintage Interfax Harmonic Percolator. It was a really neat Fuzz pedal, and AionFX provided recipes for both the normal unit and a version modified by Steve Albini. When I first started to learn to lay out my own boards, I wanted to get as much practice as possible. So I went ahead and laid out my own version of this circuit.

A Pair of Wooly Fuzz Pedals

Fuzz pedals are one of the more popular builds in the DIY community because of the variety of options, both vintage and modern, out there. Fuzz and Distortion sounds formed the foundation of rock and blues music in the 50s, 60s, and 70s with the Maestro FZ-1 Fuzz Tone commonly thought to be the first available effects pedal being released in 1962. For these two builds, I used the Aion FX Calliope board which replicates the Catalinbread Karma Suture - which in of itself is an adaptation of the earlier Interfax Harmonic Percolator. The Karma Suture is a fairly modern pedal first released as a germanium transistor based version in 2014. A silicon version followed in 2016. They're not terribly expensive or rare, but they are a great simple build which will let you get a pedal for a fraction of the cost of an original.
