I have one of the Siegmund Midnight Special amps (single-ended, 5~10 watts). I'm interested in trying a couple of different 12 inch replacement speakers. The amp originally came with a Celestion Blue, but didn't have quite enough bottom end and warmth. I realize the cabinet is small, and that limits the bass and projection. I currently have an Eminence Swamp Thing installed. It's a nice efficient speaker and gives the amp some added volume, but it has a bit too much of a mid-range peak for my applications. Any recommendations? I primarily play Strats and Teles, and the occasional P90 or low gain humbucker. Most of the time I play clean or with just a touch of break-up. No metal or high gain stuff.
