then came out with a half-baked 'Tone' bluetooth app,
was OK for some, often a flop...then they closed their public forums
Now, at long last, via a firmware update, the newish Mustang Lt 25 and LT 50
usb modeling amps have a computer based version Tone, and I found
a user demo from April 2020. Closed forums don't spread much news (muttering: you idiots)
At 10:45 in the video, the demoee goes through the steps
to create a new preset, and does quite well for himself.

Tone looks pretty easy to use, with nice graphics, and a handy 'swap-out' button.
The earlier minutes cover a range of presets and uses etc. The amp sounds/effects
are typical for Mustang, but without over-the-top nonsense, just 30 good examples
from which to modify/redo, and 30 more empty slots for new creations.
The LT 25 is budget pricedat $150 or less.
I'm hoping that Fender will update firmware for the earlier GT series to use the
computer Tone app. It installed and launched fine in Ubuntu Studio 20.04
with wine-staging stable 5.x but is waiting for an LT amp to be connected...

Cheers
