Funk-
Frank #2 gave you his layout, its a bit different than a stock East pre
the East preamps have similar layouts. (

Heres whats on my SuperJ -- top knob (concentric)
knob closes to neck-Vol (balance), treble (bass), Mids (frequency of mid)
-knob closet to bridge- passive tone
Treble is boost/cut, bass is boost only
The switches are either active/passive, or pickup selector, or bluEQube
Its incredibly versatile, but I'm mixed on it. I dig the flexibility and musicality of the pre, but I have 3 dings against it, 1)- its been difficult for me to duplicate a number of great tones once i find them, becuase the knobs move freely. So its not like 1 click on this knob and 2 clicks on this one, etc. 2) the knobs interact too much, boosting bass or treble seems to influence mids, or vice versa, and 3) to my ears, the pre is very middy. I know you'd prefer to be able to dial out stuff, because its hard to dial in tone, but my SuperJ is way mid sounding. Ed friedland got to play it and said, you can always dial out what you don't want- hes got a point.
Just figured I'd give another opinion
