I always played Marshall amps until recently when I purchased my first rectifier.I have found that the only way to achieve a decent sound is with high volumes.I play a PRS with EMG pickups,single rec,Marshall 1960a.When I bought the rectifier,I thought I would be able to find an attainable house volume without pissing off the neighbors.I was wrong.Whats up with the THD hotplate and will that be what I need to attain a good sound at lower decibal levels.Thanks again everyone for the help.
