So we've gone over Jerry's twin settings in detail, what he did and why he might have done it. I found an situation of another guitar player using a Fender style preamp in a pretty radical way... David Gilmour.
Here is a shot of David's rig from the Pulse tour, the Alembic F2b is highlighted:
He's only using the tone stack of Channel B, since Channel A was repurposed for an additional gain stage. The Inputs have been rerouted to the back by either Phil Taylor or Pete Cornish.
The settings are:
Gain: 6, Bass: 1, Mids: 10, Treble 8
These setting yield a much flatter curve than Jerry's, although they do have the same basic shape. Jerry had a much more pronounced cut on the bass end. Also note that there are 5 GE-7's in David's rig! According to Pete Cornish on the 3 on the righ and 1 on the left were used.
So for those of you that get the urge to start cranking that Bass knob up when searching for "the tone"... Don't!
