FuzzHugger FX Phantom Octave
The Phantom Octave is an octave/ring mod type fuzz that’s very interactive with guitar pickup selection and volume/tone controls. The LED pads are for the one that’s under the knob in the video below. You could use it as the on/off indicator, but it might be hard to tell if it’s on when signal isn’t … Read more

Tychobrahe Octavia
The Octavia is one of the many legendary effects to come out of the late 60s. It is also one of the rarest pedals of the era, as there weren’t many built. Like most effects of its day, the Octavia is a positive ground effect. There are several schematics for it floating around, but the … Read more

He also has his own line of pedals and this is his take on the classic Octavia (octave up) effect. This one … Read more

Shin Ei OB-28 Octave Box
Here’s a weird one for you–the Shin Ei Octave Box. It’s apparently an all analog clean octave down effect. I’m not going to pretend to understand how it works, but there are a lot of transistors. Originals used 2SC644 and 2SC666 transistors, which I think were in the massive TO-3 package. I’ve drawn the layout … Read more
EarthQuaker Devices Bit Commander
The Bit Commander is an synth/octave effect that’s all analog. It creates square wave synth tones across 4 octaves (2 up, 2 down) and it’s capable of creating a wide range of sounds. The octave down effect is generated from the ICs, while the octave up comes from the 4024 and transformer (kind of like … Read more

Here’s what Tim had to say about it: The latest Fuzz Face inspired offering. The big difference is the “Trauma” control, when used with the Gain control, will yield tones from hard fuzz … Read more
