I tend to do the same thing. The guitar I've got on my workbench right now has been my main one for over a decade and the one I had before that (also still own and may have enough parts now to put it back together) I bought twenty years ago. I've had quite a few others but they were beater guitars I bought for cheap and they never really had much to say. Amps on the other hand... I'm at the point of designing and building my own. I do miss my '68 super reverb though.
