Re: Which one of you guys had a THD hotplate AND a Legacy?
I have tried Hot Plates with several amps and they generally work better with amps that are non-master volume designs. Your Legacy has a master. Tried it with a Fender Vibro-verb and an AC-30 and was not thrilled, seemed like a wet blanket had been placed over the speakers. I would try the 1/2 power setting and perhaps a pair of THD Yellow Jackets.
