Agreed, so many variables to get your tone like the guitar, play style, entire patch and settings on the unit, impedence interaction with the cab, if you’re using IRs then impedance there, quality of IRs etc, it all matters
My mind is open to it being inferior but I just haven’t seen anything sort of conclusive about it. I see more people praise it than say it’s bad so that’s all I really go off. I’ve also never been playing an amp model and thought “this is the problem”
I’m sure it’s not fractal level deep but it’s no slouch
I've seen relatively few people talk about it at all, which is interesting to me given the huge brand name. Even the two (count 'em) substantial TMO threads here have been pretty sleepy overall. Sure, it's only been out for a bit over two years, but it's still
Fender.
My beef with it is that other than the skeuomorphic interface, about which I honestly care very little, it isn't distinctive at all. Selection is low, feature set is catching up or "us too" (still not quite fully baked scenes) in nature. Yes, some especially good reverbs, but that's not all that compelling to me all by itself. And they seem very content to play catch up
very slowly - talking about how very long it takes to add a new amp model, as though that means theirs are so much better. They may not be much worse if at all, but they're surely not (IMO) obviously better.
I still use mine almost exclusively as a practice device. Fun for getting a half hour of practice in. The interface does help for that kind of simple plug in, dial in use. But when I'm sitting down to write or record, it doesn't work for me. People tell me I'm "lazy" or "collecting amps" or some other pejorative dismissal that really says "you don't do it like I do, and that's
wrong," but I don't care. To me, the ability to page through various different and distinctive amps to try out ideas or to pair with different guitars and pedals is not only part of the fun, but part of the creative process. Fender doesn't provide that to me yet, focusing much of their low-mid gain sounds heavily on black panel amps (with similar circuits) and inexplicably putting months' with if time into two Blues Juniors and two Bassbreakers - which were both there ahead of the Bassman or the Tweed Deluxe.
That priority speaks to a market, I get it. But that market isn't me. Ironically, the fact that I have an FM9T and other modelers is probably the main reason why I still have the TMP. I'd be losing (or would have lost) patience with them otherwise.
