We’ve taken our rock-solid RAT clone, squeezed it into a Eurorack module and added CV control over Gain. The 308 will take your playing to new heights with tremolo and other distortion modulation techniques.

Features:

• 3 controls – Tone, Filter, and Drive – to customize your tone. Tone sets the brightness level, Filter dials in the high frequency response, and Drive determines the signal gain / amount of distortion
• 4 Diode Settings – An on-board 4PST DIP Switch selects between 4 different clipping diodes to drastically alter your sound. Turn on the stock version 1N4148s, LEDs, Germanium diodes, or none at all with flick of a little switch.
• Vintage Tone – The PCB is designed from the original RAT tone IC, the LM308 single op amp.
• Control Voltage (CV) Input
• Guitar AND Modular – Adjust the input impedance with a trim pot.
• Plug your guitar in using Circuit Abbey’s Axis module.
• 4hp
• Current Draw: <10 mA on only  the +12 rail.
