Mark Hammer on DIYStompboxes gave me the idea to add a momentary switch to a Ring Modulator. After thinking about this for a while I thought it be great to have both a momentary and bypass switches.
The momentary switch would turn the effect on when when the effect was in bypass or turn the effect off when the bypass switch had the effect engaged.
I posed this to the DIYStompboxes and Phector came up with a good solution. Here’s a picture I drew up with Eagle.
