I sold my acoustic bass guitar today. The fourth guitar I've sold in the last few weeks. The old battered 1950s Egmond, the Black Strat and the bowl-back acoustic were fine. I felt no pangs. I never loved them, it seems. But the bass. Well, it was hard to let it go. As the deadline approached and the ebay bidders didn't materialise I grew kind of giddy - hoping that it wouldn't sell. That would be my excuse to keep it. But in the last minute someone offered the reserve price and it was gone forever.
