Beepster,
My Ibanez was built on October of '77 according to the serial #.. The lawsuit, at least with Ibanez, was settled in June of that year. Note the headstock does not look like a Gibson headstock. I bought her in the Spring of '78 at a great little music store in downtown Denver that I stumbled onto between classes when I was going to college. Sadly, they are long out of business.
The tuners seem to be pretty good, and have always been stable. Actually, back in Denver, all of my guitars stayed in tune. Here in Fort Worth, the wild swings in humidity have a more dramatic effect, and it is much more critical to check tuning before each recording session. The wood goes crazy down here.
As to the Epi, yes, she's a lovely thing. She has a decidedly different sound and personality from the Ibanez.
i initially though that because if it's semi-hollow body construction, it didn't really come into play for this discussion.
But after some thought, I have to wonder.
I have been playing both of these guitars directly into my interface, and through various amp sims. I am listening through headphones. So, to the best of my knowledge, external acoustics are not a factor. What I am hearing is what the pickups..pick up.
Steve, you mentioned isolating sympathetic vibrations, but now I have to wonder just how much of given guitars' tone has to do with sympathetic vibrations being fed back to the strings from the guitar body.
My Riviera and Ibanez have clearly different resonant qualities. Granted, the pups are very different, but the body does seem to be a factor.
Vibrations do tend to follow fairly mathematical paths, and I can see how a radical shape such as the flying V just might have an effect on tonal qualities, as Beep has suggested.
I'm just thinking out loud here, but in theory, shape should not matter. However, collective experience seems to suggest otherwise.
Are we back where we started?
