@LSchefman I completely understand. However I am sure you can see the benefits of a modeller IF and when they actually deliver the exact same sound and feel. Its not stopping you (or anyone) from doing their best work and all I see is it opening up far more options to enable the musician to do their best work without some of the drawbacks with owning valve amps - such as weight, heat, cost etc. If all you need is one amp head, something small and relatively lightweight with all the connections you need, something that can match a 100w (or more) headroom and still be played at bedroom level or with headphones, something you can easily carry anywhere, from bedroom, to rehearsal, to studio, to hotel, to back stage, to live gig with ease, Something that can hold every amp, cab/speaker, mic etc inside, something that as a highly skilled musician with an incredible ear cannot tell the difference in sound or feel isn't that a good thing?
Whether its a 'model' of a valve amp or not, if you cannot tell the difference regardless is that a 'bad' thing? If it has no impact on your job as a musician to do the work you do because its not affecting the feel or sound then what's the problem? Surely its much more enabling to a musician to have that convenience and access to far more Amps, Cabs, mics. Surely its more inspiring for that reason as well as the fact they can literally take the Amp anywhere and plug in. You don't have to go to the studio to play on the Valve amp and can even play on the tour bus or hotels. Its also saving on the storage, having 30+amp heads a variety of cabs and mics as well as mic holders take up a lot of room that can be used to have a few more guitars - and all the money you can save by not having to replace and bias tubes, not having to spend hundreds (if not thousands) on a new Amp Head, not having to lug heavy amps around (if you are touring).
Your point about the musician giving his best can apply to digital Amps too - You can use multiple amps, cabs and mics in a studio to make the track but on tour, you probably have to use one amp and probably the Amp you are endorsed by - but you could take all your amps, cabs and mics - no need to ensure the Mic is set 'just right' and isolated to cut out any additional room noise. Probably have to stick the amp on a fixed setting for the whole gig and maybe can only switch channels but otherwise limited.
I do not see why a digital amp cannot be a valid tool to allow a musical artist to produce their best work - it is a tool just like a Valve amp is and if a Digital amp can deliver the exact same feel and sound to the point where the artist cannot tell the difference at all leaving them free to fully express their creative musical voice rather than feel or hear that something isn't quite right that has an impact on their playing. Does it matter whether the Amp is Solid state or valve - IF everything is the same?
I can agree with you up to a point. Maybe Digital isn't quite there yet where you, someone far more experienced and with a much keener ear than myself, can feel and hear the difference and that difference, however small, is a valid argument for picking valves - that difference matters enough to you, the way the guitar feels and the way the amp reacts and sounds - that's not just an artistic choice but a Valid argument as to why you prefer a valve amp, that difference can be quantified and whilst there is a 'difference', that can also be an Artistic choice too - prefer the way an amp sounds or feels whether that's a digital or Valve amp.
However, if there ever comes a time when you cannot tell the difference at all, not in the way it sounds, feels or reacts, then it can't be an artistic choice - there is no difference to say one sounds better, one feels better to play through, one reacts differently. Its not having any impact on the musician to do their best, to express themselves and have their voice, their sound. Not impacting on the way the instrument feels and reacts because al of those things are the same. They can take that sound anywhere easily - even as hand luggage on a Plane because its small and light enough to do so. It takes away a lot of the worry, the concern and adds to the flexibility and variety of rigs they can have.
I am a 'musician' too and one that has always said 'it must be valve', I would welcome the day that I can have a small, lightweight amp head that can give me a massive range of Valve amps, as well as the variety of cabs, speakers and mics, so I can expand my Amp collection as well as eliminate the need to carry a Heavy Marshall JVM410c 2x12 without feeling like I am compromising on tone or feel, not feeling that something isn't quite right and the amp isn't reacting quite the same, then I welcome that day. I wouldn't need a cockpit like Tim Pierce or have to go to a studio to try 30+ amps to find the right one for the Job. If you, your client and your audience cannot tell, even if they can name the Amp of the digital model you used, then I struggle to see what the issue is. Surely it doesn't matter if the guitarist cannot tell or feel the difference and the end results are identical
