I'm in the market for my first PRS guitar. It's been mainly Gibsons and Fenders so far and now I've set my eyes on the 408 with the tremolo arm. I've never played one, as they're not available in stores in my area. The nearest store that stocks PRS guitars means a 300-mile return trip. I will go there eventually but would like to get as much info as possible beforehand. Obviously I know about the switching/splitting system and all that but would love to hear more personal feedback. Tone and feel of the guitar and, most importantly, the difference in neck sizes. Difference in "Pattern Thin Neck Carve" and "Pattern Neck Carve"? Is the latter the same as "Pattern Regular"?
