Hi Sheldon,
I recently bought a used Super J4 P/J (Serial 3757 with batteries under a Baltic Amber pickguard) and it plays great! The Aguilar preamp is so much more musical than either the preamp on my G&L L-2000 or the one on my Fender Jazz Plus V. The controls, however, are not exactly what I expected. From left to right, they are:
A) Master Volume
B) Rotary Selector
C) Bass Control?
D) Treble
I think that the treble control may be a hybrid treble. It's got a centre detent that sounds pretty musical, and it sounds like active boost/passive cut to me. I should make it clear: I don't pretend to be an expert on preamps at all. I've always preferred passive to active, until now, that is, that I have a smokin' Dingwall SJ. (Even my Afterburner I was passive.)
I have two questions:
1) I think that the Aguilar is an OBP-1. (Please correct me if I'm wrong!). Aren't the controls for this usually volume, selector, treble, bass? [b:296dh93n]Does my SJ4 have the factory layout, or has this bass been modded?[/b:296dh93n]
2) What is control C) (third from the left)? It must be a bass control, but it behaves unlike anything I've experienced before in active mode. It doesn't alter the bass as much as I would expect. My other preamps take the bass frequencies from meek to in-your-face, but the response of this control through my Mesa Walkabout was rather even.
When all is said and done, the mysterious control didn't stop me from getting a great sound (thanks, Sheldon!), but I am just curious.
I feel funny signing G&L-Forever. I love my SJ P/J, and I'm still lusting after a Super P.
GLF (for now)
