Something that made my new seven even more interesting is this tuning: C G C F A D D. basically six string drop C with an additional high string. That way I can play a lot of cool stuff including periphery where they play drop C with the lowest string an A. Now it does get a little tense, do you think its fine to do that? I figure its basically like using .13 to .59 on a six string in drop C (although with 26,5"). I use EXL110-7 (10-46 with a 59 on the lowest). I don't see any change in neck relief so I think it's perfectly fine & save to use, right? And I don't use my six string because it's perfectly set up with 10-46 for my band and tuning it to drop C doesn't yield great results.
