I bought an used resonator guitar from eBay, and I found out it has some kind of pickup.

A pickup is a nice-to-have feature, no must-feature.

I have not seen a pickup like this before. It has no battery. After I connected it with my amplifier, no sound came out of it. I think this is just logical, since a pickup usually requires a battery.

So my question is, what is this and how can I use a pickup like this? Or maybe it is just a fake, to sell it better?

Note that there is a white strap under that black thing, so it is meant to be removeable.



That looks like a piezo-electric transducer, which wouldn't need a battery. Most types of pickup don't use batteries, as far as I can remember.

I can't say why you're not getting any output, though.

  • Yep - it shouldn't need any power. Output should be around the same as a normal passive pickup, so check the wires and connections inside that socket.

  • Acoustic pickups normally do because they use condenser mics, but yeah, this is a piezo-electric transducer or a contact mic, neither of which should need power.
