I used to have a 20/20, but sold it way before I got into MTS. It sounds really good at lower volumes, but at loud volumes it lost it's low end. Actually, I think it pushed more mids at higher volumes.
I don't have the 20/20 anymore, but I've owned three over the years. They are very reliable, and work great. I did the 'deep mod' which helps reduce the huge mid hump at higher volumes and brings out a little more bass. It's very easy to do and sounds awesome. I made the mod switchable on one of them so that I could go back and forth as well.
They are nice amps, cheap to re tube, small and light!

I did the "deep mod" on one of my two 20/20's (the other is still new and under warranty, so I'm holding off on that one). I used push/pull pots (now available direct from Mesa) to replace the stock VOLUME pots, and made the mod switchable for each channel. I would have rather used the PRESENCE pots, but alas the transformers get in the way so you can't.

I'm running my RM4 into a 20/20 and I like it alot. I may do the "deepend" mod - but I've never had a problem. The biggest negative for me is that it's so loud - even at only 20 watts. I end up turning it down to 50-70%.
