Dude - it is 2024 - there is no reason you have to play an amp.
Gave up on those a few years ago. No one cares.
IF you are using your amp as your monitor, and having it mic'd as well, here is a potential issue, Especially if you have some direct and some cabs on stage; To hear yourself over drums etc, you may have your amp cranking. But that can put a lot of sound coming off the stage directly. So imagine left guitar has sound punching front row/table in the face, while guitar right is coming off the mains only. Will sound like crap.
That said, current modelers are the bees knees. Doesn't matter if you are using the Soldano pedal, the Iridium or that new Boss box, something like a Sans amp or whatever. And of course, Helix, AXFX, Headrest, Boss, and so on and so forth.
Don't get me wrong...LOVE my my Mesa head and cab. But it's big, it's heavy, it requires more gear, is more of a PITA to get right soundwise, and generally DOES require a sound guy.
Now - as for good modeling....
#1 Sound guys love them. Mic's not needed, nothing to bump, signal is loud and strong.
#2 It's freaking lighter/faster to set up period
And in whatever random sound environment, through whatever speakers, etc...the only person hearing your Uber-tone is you. And that's like your opinion man. What makes the band cook is the band. Not your pedal of epic living room tone.
To set up a modeler to sound good - simple:
1. Pick an amp model, pick a cab - and lets be honest...even crappy modelers have more and better speaker/IRs than you do.
2. Don't over do it. As always...
3. Listen through a cab/speaker/monitor like the PA will be and set it up using THAT. Not phones, not a FRFR, not a guitar amp. A PA speaker. rent one for a weekend if you don't have one.
4. Get a really long cable, or wireless and listen from the house.
5. Tweak the settings with the band - which is what the sound guy is doing with the EQ once you are in the mix.
Then just use your own powered monitor and turn the knob as loud or quiet as you want.
How the signal gets to the board does not matter. My stage setup is guitar into Boss SD1 > JCM800 > Marshall 4x12 with Greenback 25's. It sounds fantastic. How do I know? we have wireless units and can stand out in the room and listen.
As for sound guys - Foockthemalltohell. Except for the rare good one. Don't use them anymore except special occasions.
- Too many former players who think they can do sound
- Too many old blind guys with bluetooth pads accidentally hitting the wrong slider and goofing my monitor mix etc
- Too many dance club guys mixing rock like it's yo MTV Raps. Heard feedback about that from a Night Ranger show last week. Happens to everyone.
- Too many "former large club sound engineers" charging as much as the band makes
- Too many wannabe record "producers" who keep futzing with reverbs, delays, mixes etc
We set our sound up, we save the profile, and we check with the wives - who are harsh AF if something doesn't sound right. Next time, we pull up the preset, we do a quick check, tweak EQ for room, and done.
Don't get me wrong - still love and will use my amp when the conditions are right. But I spend way more time focussing on the playing and the performance than the sound going direct.
