This is just a suggestion for something Kris could include in the Masterclass.
While we all probably accept that a guitarist should learn a riff through and through before worrying about the tone he's getting, i think it'd be nice if as an aside to the solos Kris teaches if there were some specifics on what he used to get that particular sound.
I know we don't all have the same equipment to be able to replicate each others sounds, but some things can be converted across equipment and so on, and occasionally some people -will- have the same equipment anyway.
Take Curious Coincidence, there's a very nice sound on that which I wouldn't mind learning how to come up with. Perhaps it's not about just copying the numbers but learning more about how to come up with really nice sounds, what to look for, etc. I know some guitarists really struggle to get good tone out of their guitar/equipment; many struggle just to make their sound cut-through, e.g. any note they try to hold or bend above about the 15th fret dampens and dies (in which case Kris' notes in the extras section about setting up your equalisation would be a good step) - but more indepth stuff could be put out there on that kind of stuff.
I don't know if it'd be a good idea to actually do a video tutorial on this or whether Kris would be willing to; like showing what happens when you use a lot of <some setting> or too little of <some setting> and how this all depends on the acoustics of the room, and so on. Also guitar information, whether you might get a better sound for a solo with single coils or humbuckers (I've noticed things can be a little harder to sound with bends and top-end fretwork on my Fender Stratocaster).
There's probably a whole world of other stuff in that region that could be mentioned or touched upon. I guess you could call it general tone wisdom, or something.
Just an idea.
