I've been pondering having a custom guitar built for me, and I decided that I would either want a string-thru body Tune-O-Matic bridge or a fixed string-thru body bridge. Problem is, I can't find anywhere on the web (Schaller, Gotoh, etc.) that manufacture 7-string tune-o-matic bridges. Even then, I wouldn't want one unless it was locking like the Tone Pros bridges. And that raises another question: Would the tune-o-matic bridge be compatible with the wizard radius? I know with a fixed bridge like on the 7621, 7421, 7321, 7521, 7221, etc. that each saddle is adjustable so the radius doesn't matter as much, but the tune-o-matic saddle heights are set. Which would you reccomend either way considering all factors, a string-thru body tune-o-matic or just a string-thru body fixed bridge? Also, I know Graph Tech used to carry 7 string sets of String Saver saddles for non-tune-o-matic bridges because I was considering getting a set for my 7621, but their site doesn't list them anymore. Do they still carry them or do I have to special order them or what? I don't care either way, I just want them. I'm used to special ordering, since pretty soon here I'm probably going to actually get a 7-string set of Sperzel Locking tuners (the dealer near here says Schecter orders them in bulk so he could order a 7-string set from them )
