OVERALL OPINION

I have been using 4 mois.Jadore basse.C this is the same as the bass cort b4fl but new version. I love the slide manche.J 'had tried a model before buying it (notably a Fender) but I cracked on the one. ATTENTION the fretless bass are not suitable to all kind of musique.J 'have seldom (never?) Heard a fretless on a group of rock or metal. Shame for metalheads because it's much more enjoyable to play.

CORT So Excellent value for money
This choice I would do without hesitation. I tried the C4FL and there is a good difference between the two, I tried the A4FL and I have not found the price difference justified.
here I am doing my best to notice.
