A few days ago, I discovered a beautiful thing. I have a Vox AD60 modeling head as my practice rig. I have it plugged into a Marshall Jubilee 4-12, but also decided to use the AD-60's preamp out to feed the FX return of my Matchless Chieftain. What I ended up with was a Jubilees speakers and my Matchless's power section and speakers. This is the future of modeling in my opinion. Modeling amps have the perfect preamp section. Tube amps have the perfect power section. It's being perfected as we speak, but there are benefits to SS and all tube. Why not take the benefits of SS and make the most of them, via tube power? Line 6 knows it, you know it, and I know it. The amps of the future, in a perfect world, will be something similar to a Line 6 Vetta II, being fed into something like a VHT tube power section. They're trying to make them compatible now, but with a few more years of SS/tube interface, we'll have the ultimate amp. I'm sure of it.
