My settings on the video, on CH2 are: everything at 6, at a starting point, and usually i leave it as is, depth 5/6 ( depending on what spks i'm using ) feedback 1/2 ( depending on what spks i'm using ). I have two cabs, one with Celestions 75w, one with Greenback 25w, the 75w are more V-shaped eq sounding, so i back off on the depht & feedback, the 25w are smoother sounding, more sweet mids, less bass, so i ad bit of depht and open the feedback for extra "bite". With the mids, i find myself adding bit more , if i'm using the 75w spks, bit less with the 25w.
The issue with the loudness of the amp...yes, it scared me, at the beginning, how loud it gets as soon as you turn it up, i asked the engeneer/designer of the amp about it, he told me that the amp is designed to be "up/gained up" at any volume, so to get that thick/overdriven sound, the master is not a conventional master, it keeps the sound steady at any volume, and since we all like that crunch tone, the amp gives you that tone from the beginning. I got used to it, at live gigs i do bring it up 3-4, and i like the fact that it's the same sound i get at home. My Van Halen tone on my video is nice, but if i want to be totally honest, let me tell you this: i use the CH2 because i'm....lazy!!! LOL. I use CH2 because, since it has the extra gain, it gives a more compressed overall sound, that, for me, it makes it easier to play...i give it a bit of a boost with a pedal and i get a great sound, BUT, if i want to hear yet a closer-to-Eddie tone, then, CH1 is where i find it. CH1 needs to be pushed more, with a good gain pedal, to reach the level of distortion needed, but, CH1 is truly like a Plexi, where the sound is open and responsive, i have a original 73 Marshall hand-wired-with Mullard tubes head i bought when i was a kid, that sounds like... ( GOD ) and the CH1 is right there with "that" sound.
