Interestingly I have been doing some reading on materials made in sound production. There is some scientific findings that the material does not make as much difference as the design. . . . One guy for example built trumpets out of PVC and as long as the valve structure, tubing thickness, length, coil, etc. were identical the sound was supposedly identical. Quite interesting stuff. . . . It would be interesting if Ovation made fiberglass guitars that were identical in structure and design to a Gibson Hummingbird for instance and one could compare the two!
