Oakley Analogue Overdrive and Distortion Module

via Oakley Sound:

"I've done a 3U (Euro/Frac) version of our popular Overdrive 5U module.

More information about the new PCB here.

Boards are available from Paul Darlow at Krisp1."

Constructional difficulty: Our easiest 3U module.

Overview (see the site for samples, more info and pics):

"This is a simple but very effective waveform modifier module. It has two basic modes selected by a switch. Hard clipping is a hard edged distortion type effect useful for grunging up your signal. Soft clipping is a more subtle effect and produces a clean sounding overdriven amp sound.

Three front panel pots control the sound. Gain controls the overall gain of the 'pre-amplifier' stage and essentially determines the level of overdrive or distortion. The Timbre control is an effective EQ control that affects the frequency response of the effected output. The Balance pot is essentially a wet/dry mix control that allows you to add only as much of the effect as you want.

Voltage control is determined not within this unit, but as part of the signal chain placed before this module. Using a VCA to control the signal level that is fed into this unit will determine the strength of the overdrive or distortion. Using a VCF to alter the timbre of the signal fed to this module will control the overall harmonic level far more than using a filter alone. In fact, hard sync type sounds can be easily obtained by simply sweeping the filter's cut-off frequency."
