I have three basses and I think about a duo of basses that would cover all my needs so I'll be up at 5 if that happen. I won't ever seel my 5 strings, my 6 fretted is good and it was my first 1500$ bass and it was also the first bass I bought with my job money. Then I have a fretless 6 that I like but I which I got an unlined neck and the piezo option. This is why I want an unlined 6 strings fretless with piezo and probably a 4 strings bass fretted for when I have that slap bug or to play some music that I feel is kinda silly on the big 6 strings.
