Circuit diagram analysis of Angry Beard III electric guitar effector

Here is the circuit diagram of the AngryBeardIII electric guitar effects pedal. Build your own guitar effects pedal because guitar effects kits on the market are very expensive.

The op amp can be any single low noise op amp, the original NE5534 is used. The 2N44 could most likely be replaced with other PNP Germanium transistors without much change in the sound. The switching aspects are omitted from this diagram, but you would probably want to add some type of bypassing for this effect.

This emphasis switch selects the tonal style, which can be extended to include a wider frequency range, but too small a capacitor value may cause oscillation.

All taming company internal confirmation of this effect has been omitted, but is easily added. This can be noisy, depending on the platform, so a capacitor value of 10-15pF? You can put it in the loop of the op amp if you're worried about too much squeak.
