I bought my first Gibson bass at the end of 1998/beginning of 1999, it was a 1997 modern day TBird which I still have (I've never sold a Gibson bass in my life). An SG-Z followed comparatively quickly, but the collectors bug only really bit me when in a whimsical mood around Christmas 2002 I ordered an RD Standard, a Victory Standard and a G-3. When they arrived, I liked them all
and from then on the disease spread further and further ...
By the time I joined the Dudepit (in the summer of 2003 I believe) I was already around a dozen Gibson basses or so and the current collection is (the BFG LP not yet named):
