I have the original 2X12 cab that came with my Solarus back in the 60's, but I recently put Celestion "Hellatones" that I bought from Avatar in it; A combination of a Vintage G30 with a G12H30 and I couldn't be happier.
My point was that, depending on how much you want to spend, an Avatar 2X12 guitar cab might do better then fine. I can't speak from experience as far as their guitar cabs go, but a have a couple (3 actually) Bass cabs and they are terrific.
