Amp that you have owned that gaves the most feedback

For me it is my epiphone 10s

all the amps that I've owned have given loads of feedback when turned up loud and boosted with a pedal

+1. With the amount of dirt and boost I use, I could make anything feed back.

i can't really answer this question. all amps produce feedback if you turn them up loud enough, or if you get close enough to the speakers. the different degrees of feedback depends on pickups, position of the guitar in relation to the speakers etc. so i don't think you can really discuss amps in terms of how much feedback they produce.

[Superfuzz]

it depends also from the guitar..

I'm not sure about the most, but my JCM800 Series Marshall with two 4x12 cabinets was the loudest!
