I’ve got this wild idea of installing a piezo element within a semi acoustic (thinline Tele) I’m building, so it can also act as a percussive instrument as well as standard guitar playing. With only one output so I won’t need a second cable or amp.

It may have a switch to turn the piezo element on or off, and a resistor in the wiring to prevent blowing up the amp.

Anyone know how this may be done?
