Info about the original:
The Keeley Oxblood Overdrive is our response to everyone kloning pedals.
We wanted to build a new circuit that let players blend from perfectly clean to amp-crushing roar.
We wanted that impossibly huge and focused midrange that makes any guitar… Strat, Paul, Tele, sound incredible. We knew we could do it our way and offer you more tone.
So we designed this pedal over the course of a few days to outdo the klones.
With the Keeley Oxblood Overdrive you roll off the Drive Control down and get a perfectly clean sound, you can dial in any amount of distortion and volume to stomp an amp into pure tonal nirvana. The Keeley Oxblood Overdrive offers you two ways to clip and saturate your signal with overtones by selecting carefully chosen diodes. Magical and Mythical, Monstrous and Most Satisfying they are indeed.
