It's called GAS: Guitar (or, more broadly, Gear) Acquisition Syndrome.
Yes, there is most definitely an N+1 issue with guitars as well... just ask Mrs S
OK, maybe not so funny (again, just ask Mrs S).
I bought my Kaitai in April of 2006
I bought my Reno in April of 2007 (I *think* it was April, anyway)
But, now Spring (and the return of DST) is imminent and I find myself with a carbon itch and -worse- I want to scratch it 'till it bleeds.
I don't need another bike.
I love what I have and can't them enough as it is.
Why is this happening to meeeeeeeee.......
