[1173] Relay Bypass Revised

true bypass relay
The relay bypass is back in stock and I made a couple of changes to the design before reordering the boards. It now has a jumper that allows you to select whether the bypass powers up with the effect either on or off. Previously it always started with the effect off, but now you have a choice of how to build it. I also have a limited number of soft touch momentary switches available for purchase with this project.

Order the AMZ Relay Bypass.

Parts Kit now available
