Hi: I been playing fiddle long enough that I'm very accustomed to listening to whether my neck fingers are in the correct place. However I'm not use to listening to tuning on bass frequencies. I currently have a fretted and a fretless acoustic bass with just dots, different makes but same 32" scale length. I'm considering going fretless only, 'cos I prefer the sound and feel. Is that a good idea, and if I do, would I want to replace the fretted one with an unmarked (or dots only) neck, or one with lines on? Thanks, Max
