So has anyone ever make the backwards transisiton from an unlined to a lined fretless fingerboard? I wouldn't say I made the transition deliberately, but I just bought a vintage lined fretless Aria Pro II (converted) cause I spent years trying to find it unlined with no luck. Anyway, it's a trip playing fretless with lines. Trying to play directly on the line is so strange. Don't know if I'll ever really get used to it without screwing myself up on fretted and unlined. Anyone else ever experience this?
