Specifications

The OD820 circuit is basically a hot-rodded 808 with a few special tricks. After a JFET input buffer, the signal is sent a dual-gang Drive pot where it is split between a clean gain stage and the overdrive stage. As the Drive knob is turned up, more signal is sent to the overdrive stage while the drive of this stage is also turned up. If the Drive knob is turned down, more signal is sent to the clean gain stage and the drive of the overdrive stage is turned down. At 12 o’clock on the Drive knob, signal is split 50/50 clean/overdriven.

The OD820 features a standard 808-style tone control. However, the entire pedal is running at 18 volts via an internal voltage doubler that bumps up the clean headroom and provides greater output and a fuller frequency response than the typical 808 circuit – in other words, no midrange spike!

Even though the 820 circuit is running at 18 volts, it powers up off standard 9 VDC via battery or a standard external power adaptor.

The OD820 features buffered, Mechanical bypass switching with a low impedance output, allowing it to drive long cable lengths or other effect units without loss of signal.
