As I stated in my earlier post, I'm considering buying a fretless (probably a Fender Jazz). As far as playing, I really like jazz and ska. I play with lots of slides and sometimes end up playing a lot of drawn-out notes that sustain for a couple of bars. I play with a pretty strong fretting hand. Is there anything special that I need to know about playing a fretless? Obviously, there's the intonation, which I'm willing to learn. I assume that since there aren't frets, I'll have to press down fairly hard to get a good, clear, note (but as I said I have a pretty strong fretting hand - comes from having a pretty high action). I'm sure I'm overlooking something, but what is it? Help please!
