HipKitty Oxblood Distortion

 Here's your Fuzz Friday fix. I'm calling it a fuzz anyway since it's just a modded Fuzz Face with an input buffer and a treble cut control at the output. It's supposed to give the boxy sound of a cranked AC15. Here's HipKitty's description:

The Oxblood Distortion was designed to emulate the tone and response of an old Vox AC15 with added gain at the input stage. Unlike other Vox-like pedals which emulate the tone and response of the Vox AC30, only the Oxblood Distortion emulates a boosted AC15.

Unique to the Oxblood Distortion is it's ability to make a "large" amp sound "small" and in hyper-drive with the tone of the AC15.

Also unique to the Oxblood Distortion is it's controlled output. While other distortion pedals use greater than unity gain at output to alter the user's amplifier input stages, the Oxblood Distortion does not. This keeps the true tone and response of the effect intact throughout the initial preamp stage of the amplifier in use.

    1. Not sure about the hum. But the Gain pot in this effect is supposed to cut the signal if turned all the way down. If you don't want it to do that, put a small value resistor (470Ω-1k) between lug 1 and ground.
