Yup. It's not nearly enough to pull up an amp at its defaults and a "matching" IR and have it all work. Time spent dialing in the amp for the IR is what is always needed and that's something that's independent of the IR used.agreed. i always think that the Preset is the best way to have "matched amps and cabs." either free or paid, the Preset allows someone to curate exactly what someone wants. rather than the machine trying to figure out what "ideal" means to you. there are millions of guitar players and the same amount of opinions of "good" "ideal" "best" and all the other words like that.
