Ok, I'm looking into buying a new guitar. This one is most definitely going to be a customized Carvin guitar. For the most part, I know what I want, but what I'm a bit confused (for lack of better say) on is the wood for the neck, fingerboard and body. I know the jist of how the wood effects the guitar in tone, weight, and sustain and what not. But what I'm a bit uncertain of is how and any other characteristics of tone difference. So I was browsing through the website I saw various different wood options for the neck and body. I felt pretty certain that the different wood options were for more than a cool swirly look under the paint job, but I don't know what. What experience I have with different woods is a mahogany SG with a rosewood fretboard and a Fender Strat with what I'm pretty sure is a maple neck and a body that I don't know. Both sound different and feel different and I like both of the feels the same. But I'm kind of wanting maybe a new feel and tone. The guitar will most likely be geared towards metal if there's a better sound for that. Also, there were some options on different finishes. How would that effect it as well? Thanks.

Here's a link to the page so you can all see for yourself their wood options and what have you.
