Yesterday I tried out a Luke ltd edition and a Silhouette. They are so well put together and feel so sturdy it's unbelieveable. I don't think they're the prettiest guitars around but the Luke especially was very comfortable, and the neck was a first for me; I've never played a guitar with a V neck before, it wasn't too bad- it played quite fast although the frets are really low profile. The EMG single coils sounded ok too, not a huge amount or character but better that I expected. I wasn't so keen on the 85 humbucker though.
The Silhouette was quite nice too, a big fat round neck, again quite comfortable though and bigger frets so bending and vibrato was easier.
I know a few guys here have the Petrucci model, and the 7 string is probably the easiest playing 7string I've tried but in general what's your opinion of Music Man guitars?
