dots?

[Philbiker]

none (you know, like some fretless basses)

I sure hope I never have to play a fretless bass without side dots!

Having "grown up" with a jazz bass (1960 stack knob) I have always liked dots. Granted, an unmarked fretless board looks great, but I found I need the crutch even more with a fretless (I had an unlined fretless 6 for a while, but I traded it).

Ric triangular inlays are the best
