and that makes no sense to me given the choice of modern high gain amps. It should be easier to find an amp that makes the soundss you want.
as I said, clean boost / EQ can provide different flavors. Dirt pedals will color the gain structure of the amp = the wrong amp for the gain you want. I guess it's cheaper than having multiple amps, but there are probably more than a few choices of modern high gain amps that will give you the sound you want.
That's why I have several amps, and don't use dirt pedals. Each amp I have does what I want it to do vs one amp and a collection of dirt pedals. I'd rather spend the money on an amp not dirt pedals.
I'd only use dirt pedals if I was playing live and needed a variety of tones with the smallest amount of gear. But just playing at home these days, I can have several amps that I like and use for different flavors.
Dirt pedals are anachronistic holdover from the days of mid/low gain amps from a bygone era. Old habits die hard.
