Your 'best rig' moment

Fuzzdog

I think my best sounding rig was my '76 335 going into a JCM800 for dirt and a silverface Twin for cleans, with nothing but an A/B box and an occasional Crybaby in between.

If I still had the budget (and non-aching spine!) I had back then, I'd still be playing through the same rig today.  I'd probably also be a lot more deaf than I am.
