That looks amazing! I really like that top.
I've just gotta say that I tried a four string Roscoe LG at Guitar Center a few months ago, and while I liked it a lot, I didn't think it had the same kind of sound that you people have been describing at all. The concensus I'm getting from everyone is this:
"P bass on steriods, big fat fingerstyle sound, kind of nice slap sound but diferent, overall better for fingerstyle than slap."
The bass I tried had a very clear, modern sound, with plenty of low end, but I wouldn't describe it as particularly huge sounding. I thought the bass was just incredible for slap. I'm one of those guys that never slaps at all, but I thought this Roscoe was just begging for it. To me, if anything, that's where it excelled.
The only thing I could accurately compare it to, was a Pedulla Thunderbolt that I had just played right before. I thought the Roscoe was a little more modern, and the Pedulla was actually fatter sounding, and had more low end.
Overall I was really impressed by the Roscoe, but I'm a little baffled by everyone's description of its sound. I'm definitely going to try another one when I get the chance.
