I like higher gain amps and profiles. I think this phenomenon varies from amp to amp. Some amps don't really change tone all that much when you add gain. They just get gainier. This is particularly true of master volume amps that are deriving their gain mostly from the preamp. I have found that profiles of non master volume amps do not always behave this way. Taking profile #3 and increasing the gain to the level of profile #8 doesn't necessarily sound just like profile #8. Which is a good thing, since it gives you a few more sounds to work with. This behavior may be different with lower and mid gain amps. I do agree that some authors get carried away. I bought a profile pack for the Soldano SLO 100 that had something like 125 profiles in it. A wide variety of channels, gain levels, different cabs, different mics and mic combinations. It was tiring. In the end I ended up deleting the whole set. I found one author I really like. I stopped buying profiles from other sellers unless they are running some uber big discount. Then I'll try a few.
I actually like it when people add effects to their profiles. More often than not I end up deleting the effect but occasionally I'll find a gem - either a new setting on an effect I already use or an effect I have not yet tried. I rename them and store them for future use.
