Fractal kit

The OD-05 has a standard feedback diode clipping stage similar to a Tubecreamer, but what's special about it: a parametric equalizer that allows either a cut or boost of up to 15dB in a range from 100 Hz to 4 kHz. With this flexible pre-clipping EQ you can create versatile sounds. The mids can be boosted for a wah-sound or the circuitry can be tuned to amplify the resonance peaks of guitar and amplifier. Even a Scooped-Mid-Sound is possible, which is quite rare in an overdrive.

This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 4 knobs for 6,3mm shaft separately.
