I can see the case for separate models and also I see the case for staying as we are. Either way it’s a fantastic addition.
The thing with the ‘separate models’ is, from a mindset point of view, it scratches an itch. Part of the reason we all buy profiles? We are curious to know exactly what a vintage Marshall sounds like because most of us will never be able to have the real thing. Having the confidence that we have a great profile captured scratches that itch for everyone who doesn’t have the original amp. Tone Junkie is great at making profiles for sure but he’s also great at making you want them. He knows all about that itch.
The case for doing the pedals separately is this..... ‘an expert’ is telling you that it sounds like the real deal. That satisfies the desire of the collector which most of us have to some extent.
The current method is sonically more versatile because it is a seamless blend between them all and, as pointed out, the differences are not so huge in many cases. So, in terms of being useful? It’s more useful than separate boxes but it’s asking ‘box at a time’ compartmentalised amp collectors to think differently. Most of us guitar players aren’t great at doing that! In terms of satisfying the ‘I’m using a Klon’ vibe, the blended Kemper Drive doesn’t do this because if you’ve tweaked one of the dials too far you’ve gone beyond Klon settings and might be using something else. Which doesn’t matter sonically but I think makes the ‘authentic collector’ part of the brain uncomfortable.
To please everyone’s little voice as well as remaining useful beyond reality (which the current method does) you could add individual boxes that have the range limitations of the originals but for sure keep the current blended drive too. Then those who care about duolicating the original things are absolutely catered for.
Otherwise, presets get you to the original at a certain setting but with every dial tweak you’ll have to go with your ears for enjoyment, not the inner voice that says ‘it isn’t real’.
I can see a case for both..... ears are the ultimate test but...... our enjoyment can also come from keeping the inner voice happy / secure.
Sorry for the ramble Very cool addition no matter what way it goes and looking forward to playing more. Hoping fuzz pedals can feature soon too
