7-String newbie, need a primer
Transition, don't worry about it as long as you get a guitar with a neck profile that you can live with, and if you're a Iby guy already, then you've got nothing to worry about. *I played 6 strings for 15 years and now I don't even own one.
As far as which model...that's tougher and very personal. *I have a 2027XVV and a UV777BK. *They sound completely different but they feel nearly the same to me...with weight being the exception. *The neck dimensions as listed in the guitar section are identical but it's the profile that varies. *I prefer the UV neck with its raw finish (2027 has a very light satin finish...which is now beginning to come off!?!?) *My UV fretboard is just a hair wider than the 2027. *There is more room south of my high E on the UV and sometimes on the 2027 I will vibrato right off the board if I'm not careful. *I got used to it though and I never do that anymore...except when I mean to.
Both of mine are stock and they sound just great to me. *Harmonics leap out of the 2027, even the neck pickup will give you some good ones. *The UV is a little more finicky. *As i said, they sound quite different due to the woods and what not, so that is where your choice will lie. *Problem is that if you want a mahogany seven, the only choice you have is a K-7 unless you are lucky enough to find a used CT, CST or 2027. *RG7620s are great guitars too, and a good bargain on the used market...just look a little plain jane for me though. *The UV is the best one still available that I have played, I haven't played an EB JP7 yet so I can't compare. *But you can buy 2 UVs for the price of a loaded JP7
