Pardon my ignorant questions. I'm getting small doses of info in my school work, and I'm trying to apply it to my stompbox addiction.

Let's say I have a t-flip flop, I pulse the clock with a momentary switch, and use the output of the flip flop to drive a voltage buffer that triggers a non-latching relay. That would work right? If anyone has experience with this I'd appreciate some schooling.

Do I have to debounce the momentary switch?

Yes, it sounds like a toggle flip-flop can operate a normal relay through a driver.  You will have to debounce the momentary switch because each bounce would otherwise change the state of the flip-flop.

You should be aware that some flip-flops take their feedback from the output pin rather than having a buffer there, so long runs or excessive loading can prevent them from operating properly, but the driver should make it OK.

Sweet! Time to breadboard!
