ROCKTRON O.D.B Overdrive Dynamic Blues Guitar Effects Pedal
The ODB provides the best blues tone and unparalleled dynamic control in a pedal package. You get total control over the most subtle nuances. This is a TRUE BYPASS pedal: when you turn it off…it is out of your signal path!
The ODB provides two Germanium clipping diodes that may be independently assigned to provide “soft knee” clipping compression applied to the positive cycle of the overdrive output, negative cycle of the overdrive output, or both! This gives you total control of the overdrive characteristics providing even/odd harmonic enhancement produced when Assymetric clipping is present.
Yeah, sounds complicated, but really it is simple in that you will love the tone. Germanium diodes are known for their “magical” soft clipping properties. Assigning both plus and minus diodes produces Symmetrical clipping, (both halves of the overdrive output waveform have equal volume). Assigning only one of the diodes produces Assymetrical clipping, (one half of the overdrive output waveform is larger than the other, thus producing more harmonic tones).
The ODB has a Drange Control which determines how much Soft Knee Clipping is applied. Drive Control adjusts the Overdrive gain (before the Germanium diode circuitry).
The Output knob adjusts the final Output Gain (0db to +3dBu). The Tone knob adjusts final High Frequency.
The footswitch on the Guitar Silencer controls On/Off status (indicated by the LED). This stomp box runs on a 9V Alkaline battery. You may also use the Rocktron DC OnTap Universal Power Adaptor.
