Yeah, if you’re prone to not leaving well enough alone, a Fractal unit can be a time sucker. There’s a distinction here though; the unit doesn’t make you tweak, YOU make you tweak. After enough time on the forums and seeing how other people handle it, it’s obvious that some people see all the areas to tweak and if they aren’t getting a killer sound within 5 minutes, think they need to start tweaking the deeper features. That’s the opposite way to go.
My best advice is to pick an amp you’re familiar with and leave the knobs at noon, then find an IR that’s 90% in the ballpark of the tone you’re going for and use the knobs for the final 10%. Doing it the other way around is a rabbit hole that never gives the desired results because you’re either trying to add what isn’t there or take away too much of what is. Think of it as mic’ing a cab in a spot that sounds like shit and then trying to dial the shit out with the amp, it ain’t gonna work, ya know? An IR is just a snapshot of a mic at a certain point on a cab. Move the fucking mic.
The only amps you can’t do that with are Mesa’s because you have to dial them in like the actual amps and anyone who has played a Mark before knows they sound like shit with standard amp settings.
Another advantage to it all is the Block Library; I have a bunch of IR’s stored as cab blocks for specific sounding amps; I have a few saved for Mesa/Peavey amps, Marshall/Friedman’s, Fender, etc. IR’s already paired together that I know will work with certain amps so I don’t go down a rabbit hole searching for IR’s.
Also, Cliff just previewed a pic of the new cab block their updating, it’s going to have movable mic positions like the Helix/QC, so no more singular IR’s, you can now drag a mic across a speaker to find the sweet spot. Well, once it’s released anyway.
