I never checked the weight of my Les Paul Basses before so I figured it was about time I did.
1970 Les Paul Bass = 12.5 LBS
1972 Les Paul Triumph = 10.0 LBS
1973 Les Paul Triumph = 11.0 LBS
The '72 is my player, it had a BADASS bridge installed before I bought it & yet it is the lightest.
It was done with a digital bathroom scale that only measures in half pounds.
