Sticking with just my 4 string basses.
My Warwick Thumb NT is a bit heavy and not sure i could do a full 2hr set with it. Think it weighs 4.5Kg
My Fender basses are fine. Jazz is heavier than my PJ. No idea what weight is tho but full gigs are never a prob.
My recent purchase Sandberg VM4 is brilliant. Think its about 3.9Kg.
