BTW I read somewhere that inside the 'korina' line is actually basswood which is cheap, BUT it would explain some of the resonance. Basswood is rather resonant compared to 'traditional' tone woods like mahogany and ash and alder, which were - and I think every guitarist well knows this but chooses to ignore when talking 'tone woods' - originally selected just because those are the LEAST resonant and reverberating woods available and physically strong. Leo and buddies wanted to reduce feedback and minimize any effect of wood on the sound so the sound would be generated 100% from the pickups and there would be no feedback etc. THAT was the original idea. If you want a very lively electric body, use spruce like almost all stringed acoustic instrument tops use. Mahogany etc. are used for rigid yet light backs and such because they're dead and the parts that matter for sound are spruce or maple, which also conducts soundwaves rather OK.
