Hi everyone
I am in the planning stages of a new 4-string bass build. I have based the design on a Fender Jazz Bass with a 1/4" to 1/2" thick, flat top (possibly western red cedar) and a hardwood back. Anyway, I want to heavily chamber the body to gain the warmer, more resonant tone of a hollow body but I am worried this may cause feedback issues. For this reason, I think it may be a good idea to incorporate a centre block, and this is my quandary, I'm not sure if I need to have a full-length centre block, a block only under the pickups or a block only under the bridge. I'm aware that there are various different causes of feedback (sympathetic resonance of the strings, microphonic pickups etc.) but I don't know which type is most likely to cause problems. Or will the top be thick enough to fully chamber and have no feedback issues? Would a full centre block still allow me the tone I am looking for?
Thanks
Mitch
