How do you guys deals with different guitars?
I tell them to stop the B.S. or I'm going to turn the car around!
I don't adjust my sound for the guitar, because I
WANT that change. My Strats don't put out the same sound, and I want them to sound different than the humbuckers.
I will adjust the Global Input Gain a tiny amount if I'm in
that mood and want the Strat to hit a particular preset hard, but change EQ or other settings? Nope.
I'm not really trying to compensate output, moreso compensating for a dark guitar.
IMO, if you're not happy with the darkness, then plop it down in front of your guitar tech person and explain what you don't like, and see what they say.
Pickups and the string's gauge and metal are the first things that I'd look at. I'm a big fan of PAF-type humbuckers because the originals were quite high-fidelity with lower output, more in line with a Tele. Over the years, as Rock developed, then Metal, the demand for high-output pickups came along, but they tend to be darker as a trade-off. Lighter string gauges don't have the lows that the thicker strings have; Said the opposite way, thicker gauges have reduced highs.
Some strings sound darker because of the metal in them; I use NYXL and Paradigms in various gauges depending on the guitar because they last a long time, never rust, and hardly ever break - the last time one broke, the guy who asked to use my guitar broke it deliberately (and will never touch my gear again). I run 11s on my PRS DGT for "that" sound, down to 9s on my Strats because their scale is longer and I don't like how the strings feel at the end of the night if they're too bouncy. My other guitars are PRS and use their own scale length so I use either 10s or 9.5s. The later are on my 509 which has a Strat-length neck IIRC.
