So maple oak neck with ash flooring fret board. Local found box elder veneer peg head, fender purple guitar pick fret markers. Fir cone sound well and a store bought cone cover, and varoiuos oak filler parts. . Sounds a lot loke a banjo if you listen just righ, here is a link (if it works) of a friend doing the shop bench test for quality control.
Not exactly the right way to use a rod piezo, would of been better to slot the biscuit, lay the rod in the slot and stick the saddle on top. They work great when they have pressure on them, here it`s more like a disc picking up vibrations. You could of just used a disc under the biscuit between it and cone, or even use double sided tape and stuck a disc on the cone. Here`s a pic of how I do my rod biscuits, the rod is under the bone saddle getting pressure from the strings.
Just an observation - most resos (although not all) have soundholes, as this actual allows the body to act as as a "ported chamber", and you get mid and lower frequencies projected out through the soundholes. With your set-up you are mainly getting the sound projected from the front face of the reso cone. If you make another, try soundholes, I think it does give the instrument more projection and power.
I wasn`t giving him a hard time, just trying to explain the proper way to use a rod, and the different ideas to amplify a reso build using piezo`s. I always try and give advise, it`s up to them if they use it or not.
It is good advice, but a little praise makes it all the sweeter. Make a new biscut and gravey(hot glue ) and it will be done like dinner. I have another with sound holes, have to do a side by side for cost benifits.
