Thanks again! The Emerald definitely goes on the "maybe" list. That's BD, E (not the greatest abbreviation), maybe Crawler, with the RY to fall back on in an emergency!
I like Green and Kossoff but the tone I have in mind is something like 70s/80s Michael Schenker (although he uses the wah so much it's hard to know what his basic tone was like). I guess he would have been using stock Patent Number or T-Top humbuckers, which brings me back to the Riff Raff... but then I'm a firm believer that tone is mostly in the player's hands, so I have no intention of trying to duplicate anybody's actual equipment.
And let's face it, I'm unlikely to find any pickup that'll make me sound like Schenker :( .
