This is an awesome guitar! Don't let the fact that it's an import model or an off brand Music Man copy- it is a great guitar! The burnt maple fretboard is very comfortable and the neck is nice and flat. I had almost zero problems adjusting to this guitar, it felt no different than a 6 string.
The only complaint would be the pickups, but with some adjustments to your pedalboard/rig or just swapping them out entirely, it's not necessarily a deal breaker.
With a good setup this guitar is a beast. To top it off, you get a 7 string guitar- endorsed by John Petrucci himself- for well under $1000. It may not be a genuine Music Man, but it's definitely worth the purchase.
