Better keep him away from Backporch Mojo's  git with the saw blade reso cover, might turn Bad Finger into No Finger.

Check out banjo tone enhancers for more ideas, something like this one on Banjo.com

I don't know, after thinking it over carefully, he could still finger pick...pick one up from the floor over here,  another one from over there...

For that you would need a zombie CBG like this.

Hi ED,

Just having a slow day looking on the www and came across this page which overlaps with what you are doing and thought it might be of interest.

Gents,

I found the beavers audio article interesting. I think it experienced numerous failures, some acknowledged in the article, for the following reasons:

1) Plate was too rigid for the size box used. That's why I recommended you start with an unrolled aluminum soda can.
2) Plate was not sprung, but was tied down, so tightly it couldn't vibrate.
3) Plate was mounted in an open frame box; while this is not a true failure per se, the lack of top and sides means any vibration would dissipate into open air pretty quickly, leaving no room for setting up oscillating waves as you might get in an enclosed air volume.
4) Plate was being driven by a tiny sound source located too close to the plate, and in the wrong place.

A quick 'Net search revealed the following details of plate reverb construction, which could be scaled for Bad's application:

Good stuff Oily. I have to search through my stash for a box of sufficient size for this design. I have a cookie tin with a dented lid that will be a donor for the reverb plate.

Definitely  try it out. What about springs at one end and something that allows you to adjust the tension on the other to vary the amount of resonation?

Cheers

Peter,  thanks for the idea.  An eye bolt or something hooked through one end of the sheet would be a handy tensioner and simplify mounting significantly.  I like it.

I recently built a coffee can resonator, with a cheap (guitarfetish clearance section)single coil mounted under the coffee can i am very pleased with the quality of the signal.video at the bottom of the page
