I just got a Benson Preamp today, and I am very impressed. So far, I've put it in front of a '76 Deluxe Reverb, and played it with a Les Paul with Seth Lovers and a Tele with a neck P-90. This thing is incredible. It really does sound like a cranked amp, and it responds like a cranked amp, and my DR volume is on 3.5. I understand that this is the preamp section of the Benson Chimera, with the tubes replaced by FET's. But I am shocked at how much it behaves as advertised. By comparison, most pedals seem to impart a "flavor" to the sound of the amp, but they sound and feel just like that -- an added flavor. This doesn't. Can y'all explain why and how this behaves so differently, beside the obvious fact that this is actually an amplifier's preamp section? That is, what is different about the circuitry here than in other overdrive stomp boxes or the like?
