Wow, my last post in this thread, as to number of guitars, was in 2008! And it's now quite aways off of accurate.
I currently have 25 electrics: 20 guitars and 5 basses:
Additionally, I have one 6-string acoustic, one 6-string acoustic-electric, and one 12-string acoustic. So I guess my total is 28.
Other instruments include: 1 acoustic-electric mandolin, one banjo, and one ukelele.
