Or the FM3 for that matter, it had USB issues for a long time, and even after that I got non-working footswitch issues and sometimes garbled audio that was solved by rebooting the device. Those problems are now long gone so people forget where it all started.
Bringing a new digital modeler to market is a huge amount of work when the "table stakes" feature list is miles long. I think Fender did pretty good - I haven't read complaints of any major issues with it. You can argue about specific amp models not being good enough but you can then just use some other model. You can't do much if your unit keeps locking up or crashing or if its USB audio interface features don't work reliably.
Similarly for all the shit the QC gets here, I think it was a solid launch. Personally I didn't have the power supply issues many complained about, and what was in the box certainly worked even if there was room for improvement in many areas. And I didn't have to wait for 6+ months for it to be available in my region. Neural's post-release support has been problematic for sure, but I'm willing to give companies more leeway on release since these things are complex.
Maybe today it's more difficult to launch a well finished product.
I've not bought many "new" modellers. Most of my buys are "used" ones.
I bought a Zoom G5n and a G1X Four, new ones. They had no issues at all.
Bought a used Helix LT. It had things to improve, but no issues when I bought it.
Bought a used AA12. It was what it was, but no issues present.
Bought a used GE250. No issues.
I hear about Boss units with issues on the IR thing, for instance. Or in the output setup for amp or "FRFR". I think that's incredible, even more when it seems they are not going to fix it.
I've heard about many USB fails in Headrush units. Also latency problems in their last units (fixed via updates, it seems).
Nux seems to have made it really bad with the Trident.
Not heard about issues with Kemper.
Fractal, no idea... That issues you mention are the first ones I've heard of.
So yeah... The TMP is not alone in the issues bag. Let's see how Fender deals with it.
