Dead on. I have a "stable" of guitars and switching between them is a big source of inspiration for me. If I leave the big ol' Gretsch hollowbody out I'll find myself finger-picking Beatles, old Eagles type stuff, maybe even some old country standards.(Stray Cats type "mood") After a week or so I'll put her up and set out a Paul and my mood changes to harder, faster and more distorted stuff.(Led Zeppelin type "mood") When I feel like I've beat that horse to death I'll put out a Strat which (for me) inspires more complex playing with an emphasis on chord and right-hand work . ( Steely Dan type "mood"). When my inspiration to play is deteriorating I'll clean-up and re-case that guitar - look at all the guitars I have and usually at least one "speaks" to me - begging to come out and play.
I've been told, by people whose opinion I respect, that I've kind of "missed the boat" by not marrying one guitar and taken the benefit of "familiarity" to it's peak. Could be true- but I will never know because I'm always going to be a stable-of-guitars guy. When I die my wife is going to have a garage sale you all don't want to miss! :)
