On the contrary, I think Roscoes have several quirks (Fenders do too).I think I will pass. Thanks though. It's not a Fender so I thought there might be some quirks that I need to be aware of.
- the 9/64" truss rod wrench has already been mentioned, as was the chance you may have to file down a standard length wrench (I did with one, but not on another)
- the standard string spacing (assuming you have the stock bridge, which looks like a hipshot a style, but has a slightly curved base to follow the contour of the fretboard) is 18.3mm. Most bartolinis and aguilars are bar magnets and covered poles, so no big deal, but Nordstrand makes special ones for Roscoes with exposed pole pieces.
- some Roscoes don't take right angle plugs in their jacks (recessed too far in to the body), and there's a period where the nuts on the jack were epoxied so good luck loosening them, it's just easier to replace the whole "electrosocket" plate and 1/4" jack, and if you leave off one of the washers/nuts, then it'll work.
- the build sheets recommend against using exposed/taper core strings. YMMV.
- there was a period (around early 2015, when my Century 5 was built) where they changed the neck carve and were doing a thicker, more "traditional" shape. They have since changed back, but mine is currently at Roscoe getting its neck carved to the thin, super fast standard Roscoe carve.
- Keith can be hard to reach sometimes.
These are the things I've encountered in owning 2 Roscoe basses, both bought used. But overall, they are well built, great sounding instruments that should provide you a lot of enjoyment.
