These sound so much better than the round piezos to me. The round ones are good for a certain tone if that's what you like or need for a certain song though.

Got a question, would the sound even be better with a conventional bridge that housed the piezo versus under the lid?

I did that, once on a Cohiba box lid.  It was a half inch thick, I knew it'd be a problem if I just had it under that lid.  I cut a channel into the bottom of a wood bridge, and hot-glued directly to it.

Yeah, I think my next one might have a piezo incorporated in the bridge, have to make the bridge like a conventional electric acoustic bridge for best results.

I have been using rod piezos since i started building & playing 4 years ago, i tried a disc one a couple of times but it sounded so awful i replaced it. I use a separate bridge piece with a 3mm / 1/8" slot machined in in about 1/4" deep, piezo goes in then a floating bone or horn bridge sits on top to carry the strings. Great  tone. I do not glue the piezo in at all. The rod piezos usually have to be shortened a bit, The offcuts can have new leads soldered on them & are then usable on diddly bo's!

Can you just cut one of these things shorter in length.. I have an oddball build I'm messing about with and a short one of those might just work..

Hi, yep I have cut them shorter at times.

Great concept, I use a variation by mounting the rod piezo in a grooved piece of hardwood, and capping it with a piece of chrome steel rod, part of a motorcycle wheel spoke. This assembly is mounted on the top of the box, held there by string tension. The advantage is that the sound is transferred direct from the strings with no input from the box itself.

Just found these cool little ones online.. I've ordered a couple to see what they're like.. They're just 1.6 inches long so they'd be ideal for either a 3 or 4 string..
