I should have made the original post a little different. With an untested, old amplifier, I was able to move the earth with very little effort. The amp I had been practicing with (a Carvin B800) was fine and had enough headroom. The Seymour Duncan has 200 watts less at 2 ohms and is much louder than the Carvin at the same settings.
You are comparing apples and oranges. Actual control positions are immaterial from amp to amp. You are comparing gain structure here.
