I've always kind of trolled fretless basses as being unnecessary. The other day on a gig I met a dude who says he pretty much only plays upright and frets feel weird to him. It was the first time in my life I actually considered a response to "why do you play fretless EB?" logical. I get it, they're more lyrical than a fretted bass. So I guess reason number 2 could be if you take a bunch of bass solos (why no fretless guitar?)(why are you taking so many bass solos?). Guys have told me they think they sound like an upright which sounds like idiocy to me. Are there actual musical, bass focused reasons for playing fretless? Please don't say it's more challenging. Manual transmission is more challenging than automatic but there are so many benefits to driving standard that it makes sense. Same with upright vs EB. IMO not the case between fretted and fretless. I'm sure there are many reasons out there that I'm not considering so here's your chance to change my mind.
