I'll second the FRED in mahogany. A search of the boards here brought up several recommendations for the FRED-mohog combo, so I thought I'd try it. FRED himself took some getting used to, but once I learned how to tweak the knobs (not running it full-open all the time), I found it to be very vocal, with lots of overtones from the wood. And it still keeps a lot of that Satch crankiness, which I personally love.
PAF Pro has some nice depth to its sound in the neck, and the two together in my normally super-dark guitar have a wonderful clean sound. FRED seems to lend the PRO just enough brightness to keep the "lush" PRO from degenerating into being *too* smooth and round when there's no overdrive or distortion.
Of course, my two pence only. A lot of people love the '59/JB combo, especially in mahogany. Never tried it, but the JB might be a better all-rounder than the FRED, which always has that vowel sound going on.
