I put the but end of my canjo on it and played it like a stand-up bass. Sounded pretty good. It also sounded good when I layed a ukulele on it and played do-bro style. But the best sound was when I put a kalimba on top.</p>

<p>Always remember that sound/tone results vary according to the user. We all have different ideas of what is good or bad. So you get ideas about things, but you have to try them to find out if you like it or not and you may get different results in different guitars.</p>

<p>Now that the build is finished, I have the answer to my own question.</p>
<p>The dual piezos wired in parallel are actually louder than the humbucker! If I run the humbucker at full volume, the piezos have to be set at about 2/3 to 3/4 volume to match.</p>
<p>Ill get picures up ASAP.</p>
<p>By the way they sound great. Thanks for all the advice.</p>

<p>The more expensive acoustic preamps have hookups for piezo and magnetic pickups and they add a buffer to the piezo while equaling the impedance mismatch. They can go for several hundred dollars.</p>
<p>I have a git with a humbucker and a piezo wired to separate pots(500k HB & 1meg piezo) and a 3-way switch. It works okay.</p>

Very cool that you did that experiment. I would love to do more of that sort of thing, mixing and matching 100 combos of pickups to see what happens, but I already have too little time for building without venturing too far off the beaten path.

Yep. Wiring in series increases impedance, which is already an issue with piezos. Wiring piezos in parallel reduces impedance, which is good, but I have heard it also causes a loss of signal, which is bad if you are trying to get the piezos to match the signal strength of the humbucker. I think the only way to get a piezo and magnetic pickup to play nice with each other is to run the piezo through a buffer/preamp, whether for impedance matching, signal boost, or both.

<p>The series wiring could be a good thing to have with low output volume amps as long as you use a lot of box shielding and enough insulators between the piezo's and box. Solid body gits might work better with that type of wiring.</p>
