Re: Bought A Line 6 HX Stomp.........................
The Helix amp modelling is actually excellent, though it does lean more raw, compared to Fractal Audio's Axe-Fx in particular which tends to a smoother idealized amp sound. But you can get to the same places with either. Key is the speaker cab/mic settings. Ribbon mics tend to run fatter/less harsh, especially when backed further from the cab, in Helix's cab models.
Main issue I have with Helix is Line 6 seems to like to shoot their cab models with the mics aimed at the brightest, harshest point on the speaker. Hopefully a future update adds angled & off-axis mic location options to make the builtin models more useful.
But for now, I tend to prefer to use Impulse Responses, which sidesteps the whole issue AND offers ability to change IR with snapshots, so same amp can use 8 different speaker/mic/EQ settings in one patch. Which can be as subtle as shifting mic position and angle for more treble, to entirely switching from a twin P12N for cleans, to Alnico Cream for smooth midrange, a V30 4x12 for modern mid-focus, or a G12H30-55 for classic barky dark mids with a present bite.
You can get a bundle of free IRs from Line 6 at
https://line6.com/allure/. Most IR sellers have a sample up on their website, though many of them are not representative, or of a particular speaker that may or may not appeal.
I tend to like Celestion Plus IRs, particularly the "High Gain All" [All mics] options for most of their speakers, but I'd suggest waiting for their big sales, though they do have a free sample up, I didn't think the sample was remotely as good as their own. The Suhr collection is a great place to start, a bit beefier than Celestion's standard cabs. Most Celestion Plus IRs run a bit bright, tend to slot well into mixes. The Suhrs are just a bit warmer so stand up better by themselves.
Ownhammer gets a lot of props, especially their "412 MRBW GNR M25 MMMC" set. Which is an amazing all-around G12M25 cabinet. Tend to require post-EQ more often to sit in mix, but in exchange are often more satisfying and less fussy solo.
