Make sure you reserve a little of that pedal money for a cheap pillow and blanket. lol
This concept of bass boost + HPF is nothing new. Its part of what people love so much about the Noble and the Arkham Pre's (and possibly the Mesa heads with the adjustable HPF): You can cut the lows, and add them back in which adds a different color and level of pleasant distortion. I love the Fdeck for this reason, because (with or without the OCS) I can crank the bass on my onboard pre, which is a really desirable bass boost, and compensate by tightening up the HPF a little so that the net effect is fat and juicy but not at all boomy. Its real hard to go back now to my sound without it. And I'm not even using super deep cabs these days. Really wish I had the OCS and Fdeck back when I was using Acme and Accugroove cabs which both have such stunning low end extension. Which can get a little problematic at loud stage volumes.
