I'm one of those very rare guitar monogamists. Now, the one guitar I own is a very good one (1969 Martin D-18).

I would buy another (and another, and maybe another, ad infinitum) ONLY if and when I were actually making money by playing. I spent several years of my long-ago youth trying to make a living with my guitar, but eventually gave it up.

I might add that my 42-year-old one-and-only shows visible signs of wear and use but no truly nasty scars. I'm quite unconcerned about keeping it in "pristine" condition, and am usually happy to let someone else play it, if it's someone I know and the environment is reasonably under control.

I have to agree with the many GAS sufferers contributing to this discussion that two guitars are NOT too many! If and when I start using my instrument to earn a "retirement income," I will surely consider buying myself a new toy, most likely something with built-in electronics and which will be able to withstand a modicum of abuse. A Rainsong with a pickup might be just the ticket!
