Has anyone tried making their own piezo pickup? I'm currently designing an EUB - yesterday I was pricing hardware & pickups in music stores and found an acoustic guitar piezo bug for $20 (probably sells for about $3.75 in the USA). At that price I thought it was worth a try. I stuck it on a bass - it sounded awful, with very low output. Then I put it directly under a bridge - it had a huge output but very metallic tone. Next, I got some cutters and hacked it out of its little metal case, so it was now just a little blob of plastic 1/8" thick - I put it under the bridge and it sounds amazing! Nice top-end clarity without being too edgy, huge output and solid, defined low end. The instrument it's on is a one-string test-bed I made out of flooring timber to try some ideas and work out geometry before doing a serious EUB, but it's sounding so good I'm going to take it to rehearsal tomorrow and see how much fun I can have with just an A string! I'd love to hear from anyone who's tried making or modifying piezos - I'm going to explore this option a little more before I buy a Fishman or Underwood.
