Hello Charles, I'm planning on converting an Applause acoustic bass guitar to a resonator instrument to get more volume out of it. Possible cones are your 7" Thunder cone, a 7" (m.o.l.) stainless steel dog dish, or a 9" (m.o.l.) dog dish. I was wondering which you'd recommend. Would your Thunder cone stand up to the downward pressure of bass guitar strings?
Thanks for your advice on this.
My 7” copper cone might have the strength to support it.
I have a large dog bowl bass that I made and ultimately had to place a large dowel under the bowl to use as a support because the bowl would flex and I couldn’t keep it tuned. The dowel fixed the structural issue but took away the resonating cone sound. It did increase the volume slightly from a sound post perspective by driving the sound into the body of the instrument.
Personally I would try the copper cone before I tried a pet bowl again.
