I use pitch correction software sometimes when recording fretless (upright and electric) and it works great. They also have live use real time plugins to do the same thing.  I also have a TC-Helicon VoiceTone Correct stompbox that I have been meaning to try out live on fretless bass.

I have a fretless guitar (not bass),it has really low action and I used it a few times when I was touring with an Indian reggae band and that was a real challenge to get the pitch bang on but Glissando was my friend and with indian melodies it worked well. Using modulating effects and a wah pedal helped disguise some things. Unfortunately since then I haven't found the time to really grasp the full benefit of fretless playing. For bass I'm making slow progress on double bass.

Wow, that look a band and a guitar I would love hearing for sure...

this is what mine looks like , though in alembic terms it'a "continuously fretter guitar". The artiste was Apache
Indian.
