This is a modified version of the Earthquaker V1 Rainbow Machine. I drew up and built the stripboard design for the circuit board using the Madbean "Rainbow Puker" project. The "dry kill" toggle is a modification from that design.

I increased the output level of both the dry and affected signal, wired the tracking pot backwards so it works like a short delay now (I added some delay length, too). The pitch knob has a notch in the middle so you can find the "chorus" setting quite easily.

I don't build these often since EQD still produces the Rainbow Machine. Mine is a complex build for me and I enjoy the challenge.
