"the more you play with it you will hear the tone change where ever you move it too." that is true, when i put the piezo under the inside of the bridge's bass side foot pad, the sound went too treble and finger noise is out of control. there is also a lot of radio niose even with a shielded wire from the output jack. do the strings need earthing? where are the most useful positions for the piezo? "I wired mine up with a pre amp, and a jack to run them passive. I did the passive incase the battery dies and I dont have one. Sounds much better with a pre amp. lots more volume too.

thanks very much. i built an acoustic bass (6 string) with 14.5mm spacing at the bridge saddle. there hasn't been anything on the market suitable for this bridge yet. i have been playing the instrument for about 13 years without finding a pickup system for it. it has a bridge that rests on a pad foot on the bass and treble sides, like an arch top. i put a simple piezo under the bass side and have heard great sounds, as a test. it is amazing to hear it through an amp after so long. now i can make a tidy installation, maybe a pre-amp, but the level is good direct! great work!
