That's a nice feature.
Hell yes, with a few caveats.
First, the 20/20 has a midrangier tone than the 6L6-based power amps. The good news is that you can cut through the mix better than a lot of other Recto-type amps. At band volumes Vintage and Modern both have a real snarl to them that I don't hear in most Recto circuits (other guitarist in the band has a Roadster.) Bad news is that you will never really get the humungous low-end WHOMP. Personally, I've never really been after that tone... that's what the dude with the four fat strings is for... but YMMV.
Second thing is Dyna-Watt, which can take a little getting used to. Basically, it accentuates your picking dynamics if you are playing at any real volume (you'll have to ask someone else how it works.) Once you get used to it, it's one of those things that makes you sound better than you are, especially for classic rock-type soloing or clean-ish leads
However, it doesn't work very well for high-gain shredding, sounds kind of harsh.
Clean tones are all great. It's basically impossible to get a bad clean tone.
Last thing, the 20/20 is still plenty loud. If I have it turned up halfway it's way past time to grab the earplugs, and my house is shaking.
