In my on-going love affair with funky old amps, I recently picked up a '62 Ampeg Mercury. It's a blue-check model with 6V6s and a Jensen C12R. Thing's in great shape overall. I have to say, it's one of the best sounding old Ampeg's I've had. Warmer than either of my Reverb-e-Rocket IIs or Gemini II. Gets good and mean when you dime it too. As much as I'd love to love the 1x12 cab, I can't say I do. Maybe if I was just a straight up blues player, I'd love it. But to me, it sounds a bit "small" and midrangey. I popped a C-Rex in there and that helped a bit. It does sound killer in combination with my old Gibson Invader GA-30RVT which has gobs of top and bottom (and is notably weaker in the mids). While the C-Rex was an improvement IMO, it absolutely paled when I tried it through my VT-40-style 4x10 cab. Wow, now that was a killer sound!! Big, clear, full. So I'm gonna build a head cab for the Mercury and play it through the 4x10.
