G&B 3-band preamp schematic?
Hey folks, I wonder if anyone out there is familiar with G&B company 3-band preamps. I have one that I bought used back in 2011 and ignored until recently. It came with no pots and no diagram. I should have asked right then but I figured I could find a schematic np later. Well, I can't, and the seller is no help. I have pretty good search-fu, but all I'm finding are the pot values it's supposed to use and some pictures which are confusing.
I've wired it up in several different configurations based on what I think I know, but I'm not getting any sound through it. Does anyone out there know how these things are wired, or better yet, have a diagram they could share? Thanks in advance if anyone can help, this thing is really grinding my gears.
I'm at work right now, but I can post a pic tonight if it helps.
