Hmm.
Thanks for that info.
I forgot about laminated tops.
In a book I read, it had pictures of a New York builder who carved his tops and backs, but those were jazz style guitars, not 335's.
My mistake, but they still were solid.
Many suppliers sell large pieces of spruce and maple for solid back and sides, but again, for arch top and not steel string.
Maybe the experiementation with different woods for tops have been done, (Gibson's older mahogany tops and martin's Koa tops) and it wasn't a success.
I'll keep an eye open for different woods, but might stay with the traditional, as my budget and time doesn't allow for multiple variations.
Thank again.
Mike
