I have 18. Too much GAS for sure, 100%. I always wanted to collect them. Got a decent job, no wife/kids, so it was an easy addiction for a while. I also have been in about 4 or 5 different serious bands, and I would use a different stable of basses for each. It was fun for a while, but I am at the point I would like to rid myself of many of them. I keep coming back to my main 3 or 4. My advice is only get what you play. You only need a backup or two at best. They are mainly fun to look at.
