I converted my 5 string Yamaha to fretless. I pulled the frets and redid the fingerboard, making sure it was straight, true and silky smooth. Admittedly, this was done out of boredom. After 35 years of playing in bands, I spent the last two years trying in vain to put a quality (non-traditional cover band) band together. I won't go into the gory details but every time we got close to gigging one member would pull the rug out from under us (two completely different bands no less). So I just kind of gave up and resigned myself to not gigging anymore. Just kind of thought my gigging days were over. But after months of my gear sitting in storage, and being completely jaded by commercial music in general and the local cover band scene in particular, I felt I needed to do something drastic to feel inspired to even pick up my bass at all. I thought, "What the hell...I'm not in a band and I want to do something completely different." I guess defretting my Yamaha and jumping into the world of fretless bass and playing music I never played before qualifies as "completely different". Anyway, it plays like a dream. No dead notes or buzzing/rattles, etc. and it has opened up so much with tonal possibilities. After 35 years of playing fretted basses and never really looking at my neck much anyway, the transition to fretless has been pretty seamless. No difficulties in finding the notes sans frets. It is going to take some time for me to develop my skills with all the subtle nuances that fretless affords though. It is just amazing how low my action is set now and I never realized that with fretless where I pluck, how I pluck and how I finger the notes on the neck can have such a great impact on tone that fretted just didnt have. Its kind of hard NOT to overdo the slides, vibrato and that mwah sound since its all new and fun to me and so I have to be conscious to also play it so it still sounds like a fretted bass when needed. But thus far I am really digging going fretless. Its refreshing and inspiring. And since Im not in a band currently I can just focus on being the best bass player I know how to be and play whatever music I feel like without any concern over getting a gig. Its taken me from not wanting to even play bass anymore, to exploring all kinds of new things with bass and playing music that matters to me more. Will I ever gig again? At this point I dont really care. Im just thrilled to be playing at all. Perhaps Ill form another band with completely different goals this time around.
