The Ampeg VL-503. I had one those, mine was a 2x12 combo that came with casters because it weighed an absolute ton. I part-ex-ed it for a single channel JCM 800 2x12 combo (4211?). Though THE best guitar amp I had was a Matamp 1224 MkII, which was sounded fabulous.
Pedals-wise, along with the Matamp, I had a few D*A*M pedals, the Sonic Titan and the Red Rooster, which were both superb sounding pedals.
Bass-wise, obviously my current Ric (in the avatar) is probably one of the best I've heard. It's far from A1 nick, but it's fabulous.
