I am hatching a plan for a new pedal build, but something different this time.

I am thinking of picking up a cheap piezo transducer on eBay, and putting it into a wooden foot drum/stomp box sort of thing. I have seen people wire them as a passive circuit with just a volume pot which I will try first, but if I need to massage the output a bit more I will build a piezo preamp and wire it into the wooden box. This circuit might be overkill, but I have all the components and the volume, bass, and treble controls might be handy for shaping the sound.

I just wish my woodworking skills were up to making something fancy. I can probably manage something functional but ugly.


I only have one amp, and don't really want to use a mixer to blend this into my guitar signal so I am hoping that the preamp output will have a suitable level to go into the aux input on my THR. If not I could run a simple headphone amp after the pre-amp. Or I could build a 2 channel mono mixer, but I am worried about adding extra noise into my main signal.

Does anyone have any experience with this sort of thing? Any advice or suggestions?
