I guess my few non-musician friends always seem to have trouble understanding why me and my musician friends always want to get another guitar when we already have three (...four...five...) Even some of the musician friends can't understand why I like to get equipment and immediately modify it.
The guitar player in my band just dropped another $1,000 on a brand new Martin. This would be his 6th guitar (4 electrics and 2 acoustics). Seven if you count the Bass he plays once in a while.
