I picked up my first fretless bass today, a Lakland 4401, from Craigslist today. I have never so much as touched a fretless bass until I got home with it in my hands & HOLY....COW......I think I've finally found my thing! I have been practicing playing right up against the fret on my Fender Jazz bass, to the point of getting buzz, & I guess it paid off. This bass just plays so effortlessly & sounds absolutely amazing! I'll feel a little bad for my J bass now.. The neck is so smooth & slim & the finish is really beautiful. The action could not be lower. If you're considering fretless, but, you're scared of intonation problems, find one of these with fretlines.
