I just thought it may be interesting to know what a great player (with a great tone) like John Petrucci thinks about C+/IV:
"We used the Road Kings starting with Train of Thought, I guess, and I still love that amp. Obviously it’s a Rectifier sound. I had been using Mark series amps for a long time – the Mark 2-C Plus and Mark 4s, and I wanted a change. I was doing a lot of detunes and I wanted to do something that was more of a saturated sound, maybe not so classic sounding. That’s why I switched to the Road King. It’s something that had a ton of gain.
I did that for a few albums and a few tours and then I was ready to make a change, which I usually do. And I fell in love with the Mark 4. I have a bunch of classic C Pluses, and I fired those up and they sounded great, and then I fired up the Mark 4 right next to it and I was like, “Wow. This sounds amazing!” and like I said, I fell in love with it. Maybe it’s the combination of the new guitar with that amp – it sounds amazing, so I ended up using that on the whole album. I used it all through the three G3 tours I did, and I’ll be using it on the world tour as well."
