My Number 1 rule: Never lend a mate a guitar!!! I had a nice Ovation 20 years ago that I paid some serious money for. I lent to a mate...last I saw of him and the guitar.

n+1. Hmmm. I think I might work on w+1 where w is the number of guitars I want. That gives me far more guitars than I actually need. More volume than I actually need, etc. I think you might see a pattern here.
