With regard to tubetone, or any kind of overdrive, the key in general is to control your mids. If you want some top end crunch but not a lot of low-end blurrieness, then cutting low-mids works well as it concentrates the tube tone in the upper-mids and highs. Then you can boost lows, and get a full sound. This also means you'll hear the grit at lower overdrive settings, so you'll have even less of it affecting your tone. If you want low-end warmth and a bit of wool, then scoop high mids, dial up the amount of tubetone you want, and then adjust highs to taste.
Another key with overdrive is not to have your tweeter up too high. I like to run my RS210 stack with the bottom tweeter off and the top tweeter set around 8 o'clock when I'm going with tubetone. The cabs will be pretty dark sounding at this point, but if you leave the Treble knob at the defaul setting, then you'll be boosting 1.6khz, which really adds a good bit of top clarity without the sparkle as would happen with a sealed, tweeterless cabinet. It really brings out fret buzz and pick attack which is great for that bap-bap, tick tack rock sound. If you aren't used to it, then doing this outside of a mix will sound really harsh and way too edgy. But add in some drums and a screaming guitar stack and it cuts right through with big bottom, relaxed low mids, and lots of top end crunch.
Easy to get a perfect rock tone with the RH rig IMHO.
That's definitely something I'll experiment with! However, I really would like to avoid having to fiddle with the attenuators on the back of the cabs, I mostly need to change between a clean and a gritty tone on the fly. Could you approximate some of the effect of turning down the tweeters the way you do, by using the tweetertone?
I liked the VLE for getting a vintage tone on my SD1200, but I usually wasn't really able to use it on a gig, as clean is my 80% of the time tone. The preset function is so cool for what I need.
