Re: warmoth hollow strat?
I havn't used Warmoth's particular hollow bodies per se, but I have built some chambered guitars myself, using woods, such as mahogony, that are potentially more mushy than alder or swamp ash, when used with chambering. I havn't found even mahogony muddy with the right combonation of other factors. I certianly don't think you'd find alder or swamp ash too mushy. There's also pickups and neck woods to factor in.
Korina is said to work great with the Warmoth hollow bodies, and I might be temped to try that out sometime.
