Yeah, this forum is not a place for balanced feedback on a Nash guitar
I bought a JM-63 a number of years ago and reviewed it against my Danocaster JM here (can search it if you want). I still have it and I still really like it. The pickup change made it even better and I get a great variety of sounds from it. I still don't like the trem cover aging, but I'm not a valid aesthetics person apparently since I like PRS flame tops (I own a few) which this forum also does not tend to enjoy.
And you'll see them claim Nash is a parts guitar, but then they'll recommend a Ron Kirn guitar in another thread in which he readily admits on his website he gets from top suppliers, as well. I'm not a purist; I just want whatever I buy to sound great and that is my main criteria.
I didn't pay close to $2600...which sounds pretty cray.
