I use mine for all my guitars, all the time. It's also my DI for my acoustic in my cover band. I cannot say enough good things about it - once you get used to it, it's not THAT hard to tune on one even live. Division actually uses the "sweetend" tuning.
The only downside is, of course, that you get used to tuning being that accurate, which makes you hyper-sensitive to it...
I should add that the things are so scarily accurate that some parts of the new album required retuning/punch-ins in order to get both guitars intonated together for parts higher up the neck. It really highlighted the fact that a 25.5" and 27" are going to be slightly off from one another, exacerbated the higher up the neck you go. Hell, there is one part where we were punching in octaves separately, since the two strings on the individual guitar weren't ringing quite in tune. :lol:
I've been watching some older live vids of us, pre-Petersons, and there is just no comparison. The hyper-accuracy and sweetened tuning makes us sound so much better as a band. I really cannot use a regular tuner at this point, and contrary to popular belief, it doesn't drive me crazy anymore when tuning. Well, maybe with the trem it does. :lol:
Mike and I have been bugging the other two guys in the cover band to buy one, so we can start using the sweetened tuning there, too.
