don't be concerned about fretless 'feel' references - it is a temporary insecurity
I've been playing nearly exclusively fretless EB (and DB too) for 35+ years and you adapt - as an early DB student I have always used the 3 finger left hand technique too
am I the fastest EB player? No, but it has served me well (BTW, there is no crime in looking down either)
Fair enough. Wonder if I could ask you to check that Ibanez Ashula hybrid fretless/fretted and give is your thoughts. Is it just a crutch or does it open interesting harmonic possibilities? Whoever they got to demo that thing is a monster too, makes the thing sound amazing.
