Notes: The Octave Fuzz is SynthRotek's take on the classic 70's SuperFuzz circuit, made into a Eurorack module, which has improved on some aspects of the original as well, including an increased output.

Two distinct voices like the original: switchable between scooped midrange and massive midrange bump.

Aggressive: It will sound massive and in-your-face like no other circuit can. This is for sonic explorers and heavy music only. In short, it's not useful for EVERYTHING, but the things it DOES do it excels at. Sounds especially killer for keyboard and bass sounds.

Tuned to give a subtle distorted waveform one octave up via wavefolding (see the video to view this on an oscilloscope). (Completed modules come pre-tuned; there are calibration instructions at the end of the assembly instructions for the kits)

This circuit has been optimized for Eurorack. You can find a guitar pedal version here.

Current Draw:
32mA @ +12v
24mA @ -12v
0mA @ +5v

Notes: The Face The Fuzz is a modern take on a classic sound, modeled after the Dallas Arbiter Fuzz Face but with some important upgrades and modifications. Get the original Germanium PNP transistors for that classic tone just like the likes of Jimi Hendrix, Duane Allman, and George Harrison played!

What is the difference between Synthrotek's two fuzz pedals: Face the Fuzz and the Arbiter Fuzz Face Clone? The Arbiter Fuzz Face Clone uses the classic circuit that is known and loved by many, and everybody loves a classic. The Face the Fuzz pedal has been designed with a few key changes to make it more useful to the modern musician: a wider frequency response, the ability to daisy-chain the power with a 1 Spot, and the option to use temperature-stable Silicon transistors.

The Face The Fuzz comes with hand-tested and selected premium AC128 NOS PNP transistors. All of the AC128s for optimum gain and leakage current so that they are guaranteed to bias properly and sound great! Lower gain transistorshave been chosen for Q1 and higher for Q2 according to strict standards. Be assured that you will be playing a premium product that takes the guess work out of Germanium transistor testing.

Notes: EcoSynth is a small, portable Eurorack modular case solution, designed for your desktop! It's a practical solution designed to save your hard-earned cash for modules. If you're looking for a small desktop solution to augment other desktop electronic hardware, this is for you. If you need a larger case, EcoSkiff passes on the savings for more traditional size racks like 84HP and 104HP.

OBEY is a dual-function module: one half envelope follower and one half attenuverter / offset generator.

Envelope Follower:
The OBEY takes an audio or CV signal and uses it to trigger an envelope or gate for use in a Eurorack system. It is designed to work with a wide variety of input levels: plug a Eurorack module, passive microphone, piezo, guitar, drum machine, Game Boy into your Eurorack system.

Attenuverter / Offset Generator:
Attenuvert your voltage sources up to two times in the positive or negative! The offset generator provides up to 5 volts in the positive or negative.

Specifications:
Module width: 4HP
Module depth: 48mm
Current draw:
+12V: 25mA
-12V: 18mA
