yep, I was aware of the recommended strings. In fact Godin recommends the same strings for all of its acoustic guitars, regardless of body type or ton...

Vic, you're right about it being a lot of messing around for one song. I left my guitar in open c for a few days while I fiddled around with "Friends"...

My guitar has a solid spruce top and solid rosewood back, laminated rosewood sides. Does a guitar humidifier go into the guitar, or just near it?

Thanks everyone, particularly Fretsource. That's what I needed to know (How to get the E down).

I guess my real question is, how do I tune the low e string, to C for example?
