Bass chatters... I`ve had in My life: LTD ESP Fretless, Vintage Jazz Fretless, GMR Fretless and now have as above and tell You what - amazing bass for this price(!), just the neck and tuners is worth 300 quid IMO...
I wish Cort do passive version with 3 not 55......mean 5 knobs...
BTW I think its rather 3.5kg, check Your scale bro.
