  • Hi Dan, to use this thing you just need to cut the 1/8 plug off and wire it to the pickup what ever kind your using I have not tried it on a piezo disk yet. This is neat because of the rechargeable battery but if you really want a good onboard amp try one of Bens amp kits unless you want to build your own Lm386 chip amp.

  • That's really interesting.  Would you please give us more details?  Do you use a pickup or piezo?  How do you eliminate (or reduce) feedback?  I'm very interested in putting an amp into my next build.  Thanks!
