brian d Posted February 1, 2011 Report Share Posted February 1, 2011 Could you take the amp circuits out of a cheap mini-amp and use it as a pre-amp for a piezo pickup? Any ideas how it would work/sound compared to a simple JFET preamp or any of the other pre-amps out there? Thanks in advance, Brian. Quote Link to comment Share on other sites More sharing options...
Ripthorn Posted February 1, 2011 Report Share Posted February 1, 2011 The input impedance of a cheap amp like that is optimized for magnetic pickups as opposed to piezos. If you are wanting to go cheap, look at the cafe walter pzp-1. I made one for 3 or 4 bucks and it works great in my bass. In theory, you could use one of those cheap amps' preamp, but I wouldn't, I would just make my own. Quote Link to comment Share on other sites More sharing options...
brian d Posted February 3, 2011 Author Report Share Posted February 3, 2011 Thanks for the reply Ripthorn. I'll have a look at that circuit. I don't have a lot of experience with this sort of thing, but I'll have to give it a go. Brian Quote Link to comment Share on other sites More sharing options...
Ripthorn Posted February 3, 2011 Report Share Posted February 3, 2011 That circuit was my first real try at any kind of circuit. While the soldering job is not great, it works and sounds great. Quote Link to comment Share on other sites More sharing options...
Tim37 Posted February 3, 2011 Report Share Posted February 3, 2011 i wonder how a preamp for an acoustic would work you can pick them up for about the same as that mini amp and wouldnt have to try to fit a large board in your guitar.

billm90 Posted February 10, 2011 Report Share Posted February 10, 2011 artec sound makes some pretty cheap acoustic preamps. I put the $60.00 preamp with piezo and mic blender in my 80.00 classical guitar and I was blown away with the piezo sound. the mic sucks. There are 2 places in the US that sells them for artec and they have some low grade models for 30.00. 10 more bucks gets you the piezo as well.
