What's THE best sounding Fender amp you've tried, /both vintage, old, stock modified, new, RI's etc.) and with what guitar (pedals) did YOU play through it?

I've never checked out the Fender amps that much and haven't got the possibilitie to try out the vintage ones, only the storck and RI' models, so PLEASE post your choice of amp, and tell me why that was THE one?!

Best Regards
