Maxon overdrive Od-820 Overdrive Pro

Tube-type overdrive equipped with JRC 4558 D circuitry. One of the ingredients of the OD-820's sound is its power section. Although it accepts 9 Volts, it uses a converter which changes it to 18 Volts. This higher voltage allows a reproduction of the original signal more faithful and more complete in terms of frequencies. The other secret of the OD-820 lies in its blend (blend) of distortion and "undistorted" signal. It is the Drive button which has this dual function of controlling both the gain and the mixing of the 2 sounds. Works only with an external power supply (supplied).
