Death by Audio Echo Dream 2 w. charge pump

Added an onboard charge pump to this one for 18v operation since the function generator IC XR2206P needs at least 10v to operate as it should.

Requested and verified by AlexS

Original is a buffered effect with input and output connections wired straight to input and output jacks. But you can add a bypass switch, just connect input and output connections to the switch.

Got a request for this one a while ago. Looks like a more versitale alternative to Boss HM2 eq. original has transistor gyrators but I went with op amps for less space and smaller parts count.

 Here is demo video by MTK comparing them through a Revv G4 clone.
