I'm going to shape up and do more practicing. Yeah, right. No, really! With the limited time I can set aside for practicing I have a theory it is better to do all my practicing on a fretless. Apart from being good for intonation on the fretless (duh) it should also give me a better technique on fretted (forces correct positions and finger choices) as I can't cheat between frets. Any thoughts on this? Do I miss something in terms of technique or tone on fretted bass if I do this?
