Great to have options that don't seem to work using a multiple position switch with a piezo pickup and magnetic pickup.
Like the sound created between the piezo and magnetic together. Have a temp knob on the blend till I can make a proper one.
Bought a bunch and may try integrating an additional blending pot with the other an a 5 position switch.

I used this with a Seymour Duncan spilt humbuckler and it sounded fantastic!

This gives me the ability to have one guitar with that acoustic sound then slide over to electric

I managed to wire up a humbucker neck p-up and a piezo glued to the bottom of a cake pan. For a resonator guitar I was making. It works well enough with the blend knob. The vol. And tone are just ok. This is all in a large acoustic. So I could use larger pots, which would probably be better. For the price, you can't go wrong.
