project fretless can be interesting, but might not sound at its maximum potential, if the freboard is not treated properly after the filling of the gap left behind by the fretwires.
i got my cij 62 tele converted to a fretless few years back by bro empty71.
Heh, it make it harder to play, less sustain but having a unqiue mellow sound. No matter how its being play, can get the sitar vibe plus the 'mwah" thingy with fretless bassist
Still if i have a choice, i choose fretted. The amount of modulation sometime which i connect the geetar to, it doesnt matter whether is it fretless or fretted i guess
