We had a 'studio day' at BIMM today, at which most of us played either a silverface Pro Reverb or a Harlequin which stood next to it. Everybody, including myself, thought the silverface totally blew the Harly away, and we really were tweaking the latter to try and get a useable sound, both clean and overdriven.
The resident sound engineer even stated that the Cornford sounded ''unequivocally sh@t''. So there you go.
I didn't say it btw :P
