Oh I certainly have! I've been scratching my head since I found the sweet spot just because there are two dials pretty much dimed that I never have dimed on other amps do to clarity/note definition issues....
Don't keep us in suspense! What two controls were they? I do know what you mean. I went through the same exercise with my little Blackstar. I decided to write my settings down on the chart that came in the amp's manual for future reference. I did come up with one setting and an alternate for both the clean and gain channels.

So the day when you get the EQ just right on your amp is glorious...
wait till you play in a different room.
or with a different drummer
or bass player
or at a different volume level
or in a room that starts off empty, then fills up with people
or if you play outdoors
or in a recording studio listening to how its sounds in the monitors
or in a recording studio listening back to the mix with the rest of the band and other tracks.
nothing is set in stone. that's why they have adjustable knobs on amps. Every different stage you play on and every different player you play with requires re-tuning of your eq and other settings.
Its great that you have a killer amp and have found a killer sound, just remember to be flexible and trust your ears when you are in different sonic environments.

This amp will not leave the room it's in in my house, I'm in the process of buying another amp for taking out and jamming with friends....Looking at a preamp/power amp set up for that...
