Looks like he has about 380 Ibanez guitars plus A LOT of others... You cant finance that by just doing good trades and spending less money on beer. If he did I admire him, tho.
380 looks like a lot when you say it like that, but if you've been collecting guitars for years, it can really build up. If you get a guitar every couple of months for lets say, 10 years, you'd get a very large collection. We've no idea how long he's been at it, so it could be for some seriously long time.
Sure, if he had bought them all in a short space of time, then yeah, he'd need to be rich, but over an extended period of time, you really don't need that much.
I mean, it's like me and my DVD collection. I might buy a couple of DVDs a month, maybe more, maybe less. But I've been buying DVDs for absolutely years now, so while I do have a lot, (maybe 500?) if I was to break it down as to how much I'd spend on them each week, it probably wouldn't amount to anything more than a meal at a nice resteraunt.
