Bought a used 1982 G&L L-2000 Nat. Anyone know what NAT stands for? I assume Natural but not sure. The bass is yellow not natural so I'm a bit confused. Now I'm unsure if yellow is the original color. Just bought it online from G.C. Used Guitars and salesman didn't even know what a G&L Bass was... He gave me a serial number and the G&L website said it was a 1982 but not much more. I bought it anyways since I thought it was an ok deal for $599. I appreciate any thoughts or resources.
