I made a resonator awhile back from a 25.5 6string guitar neck I had, old snare drum with a busted cover, metal mixing bowl turned upside down in a metal colander. Had a piezo attached under the bowl with double sided tape.

Never was happy with the sound. It was too metallic sounding. Decided to replace the metal parts with aluminum like a proper resonator. Got an aluminum plate from the Goodwill store. Haven't put it back together yet.

I`ve made a few rod piezo biscuits for customers that wanted to electrify dog bowl reso`s.

So the disk has a groove cut in it, the rod piezo laid in there maybe in a bead of silicon, then the bridge is set in on top so it is touching the piezo, correct?  I can turn a disk on my lathe easy.  So do you mount that disk, as in double stick tape it, to the dog bowl?  Will that suffice?

I cut a slot in the wood 1/8" wide for the rod piezo to set it. Then the bone saddle is 1/8" thick and that rest on the rod...being the saddle thickness is the same as the slot it`ll set right in the slot. I never glue the rod or the saddle in...you want the saddle to be snug but not to tight...,the pressure of the strings pushes down on the saddle which pushes down on the rod = sound.  Yeah you could use double stick tape or drill a 1/4" hole in the center of the dog bowl and drill a 1/4" hole on the bottom of the biscuit and use a 1/4" wood dowel rod to secure it to the bowl. Also drill a 1/8" off from the dowel to run the rod wire through...you`ll probably have to drill another 1/8" hole on the bottom dog bowl to run the rod wire into the box.

As far as the amp goes, the best option I have seen is to take a Honey Tone amp, and get an old car stereo speaker...  and mount it all in a Cigar box...

Or you can get LM386 amp modules on fleabay for less than $10.  Add a 9v battery clip and a jack.  but for $10 more, the honey tone has volume/tone and overdrive capability built in...

Not sure who's idea, but Wayfarer passed that one along.

I just scored two complete electric guitar pickup setups today at a yard sale for $8!!!!!!  So I have two complete circuits with three pickups each.  The way I figure, that's six CBG's I could build with minimal parts to buy to complete the other four circuits!  So based on those CBG's above, I could use a piezo or two under the bridge somehow, AND another pickup by the neck, correct?  What happens if you just use the pickup by the neck?  Do you lose the resonation?

Thanks all!

I just scored two speakers that will work in mini-amps at the dump and they had two peizos in there too!  Now to figure out how to wire two piezos and maybe a mag pickup all together.  This should be fun!

Thanks Darryl.  I'll check it out.  You know, I have found that CBG folks are an awesome sharing lot!!  I build custom furniture for a living and for the most part, furniture makers are snobby selfish pricks.  Hahahaha!  I found that woodturners are just like CBG folks.  I couldn't imagine going to a furniture makers meeting, but woodturners meetings are full of sharing and teaching.  It's awesome.
