An awesome modeler....
Well, as a long time Helix user (since it's release) I do think that my ability to build rigs is beyond satisfactory. I do, however, think there could be things that are added to make modeling go to the "next level". Personally, I would love to have a Helix unit that was ONLY an amp/cab modeler, with a couple of effects - compressors and some simple reverbs for imitating ACTUAL space (no "effect" reverbs).
Being a guy that is pretty much a "meat-n-potatoes" amp tone dude - shoot, I rarely even use drive pedals in the Helix!! It's all about the sound of the amp and cab for me. I'd like a wide selection of preamps, which Helix has. Every amp modeled has a preamp version. Then I would like power amp models:
* single, double, quad 6V6
* single, double, quad 6L6
* single, double, quad 5881
* single, double, quad EL34
* single, double 6550
* single. double, quad el84
I like the parameters Line 6 currently offers - sag, hum, bias, bias X (?). But, I think adding any presence and/or resonance controls should be added to the power section, not the preamp section. Another parameter that would be awesome is the ability to determine if the power amp is going to run in triode or pentode mode. I know having those parameters on my Rivera offered me a variety of tonal interactions that other amps didn't give.
Building an amp via modeling would be killer. Line 6 already is using component-based modeling in the HX models. Just by taking some time to work with an amp designer on modeled power amps (of course, these would more than likely have to be based on original builds as opposed to direct classic power amps), Line 6 COULD make a product that enabled the user to "build" their own amp.
Problem? Mot guitarist are stuck in the "copying" frame of mind:
"I want the tone Jimi used at Woodstock!"
Not:
"I want a great, original sound to amplify MY guitars in the way that makes them sound best."
Personally, I have always considered myself an "artist" first. I paint pictures with sound. I create original music that expresses my thoughts and feelings. I want to sound like ME when I play guitar. Pretentious, in a way - but in 35 years of playing I have only learned a handful of other artists' songs - and tend to forget them almost as soon as I can stop having to play them.
I mentioned that last bit because the concept of a modeler that focused on allowing me to "build an amp" instead of being pre-loaded with a ton of tones that cop that "sounds of popular guitarists from over the years" is VERY appealing. However, I am more than likely in the minority....
Just my thoughts on the topic, lol.
