Hey all, I've been looking around for a schematic to build my own tuning pedal but haven't been able to find one, if anyone on here either knows where I can find one, or any advice on building a tuning pedal, it would be apprecicated.

Unless you really really want a challenge, I wouldn't try it. It would be way to complicated. Just go out and buy the $20 Behringer pedal tuner.
If you could blow up the world with a flick of a switch,
Would you do it?

If you could make everybody poor just so you could be rich,
Would you do it?

With all your power,
What would you do?
