Hey all, thinkin' about putting a fretless neck onto my parts jazz, but wanted to know the pro's and con's of lines or no lines. my Roscoe doesnt have any lines, which i kinda like, but i guess having a marker on the board itself would help. but how many find it annoying with switching between fretted and lined fretless? also, i read its possible to intonate the bass so if you can fret "between" the frets? anyone doing this? how's it going?
