Talkbass.com is the only place a stack of 16 bass cases impresses anyone. I feel shame for my stack of basses, and I do still feel a pull towards eBay, etc. I do think it's an issue, and I believe I have undiagnosed ADD that may weigh in on it. I legitimize it by saying I buy broken ones, and buy only when the prices are WAY LOW, fix them up to sell, which is kinda true, but I usually don't get around to selling... especially the ones I think are super cool. I've been feeling a purge coming on for awhile. Maybe this winter It's too busy now.
