This 150 has one of the fattest necks I've seen on a 150. It's really quite nice. And that top is incredible. It's a wonderful instrument in every way. It will sound better once I upgrade the pickups.
The 594 is different. Maybe it's the poly finish, but it just doesn't feel as warm in my hands. The 10 inch radius feels different also. And since this is an SE, the stock Asian pickups aren't the greatest. The neck is chunkier than any PRS I've played in the past. It is a really nice guitar that I don't really have to worry much about if I play it out. The frets felt very tall on the 594. I'll put a different set of pickups in it to see how I feel about it later. These are both keepers.
