So I've been thinking about making the leap to fretless six string bass. I Have played fretless MIM jazz for years and I like it but want more range. Years ago I used a EADGC tuning on my Stingray 5. I liked it alot but missed the B String. I've been checking out the kingston Z6 bass for a while. I am probably going to buya kingston Z fretless anyways but I can't decide on a 5 or a 6. What are your thoughts, questions and or cry of outrage?
