I haven't, I think it's probably roughly in the same class as the Quilter Mach III
I will say quilter's commitment to class D (which I assume the fender is as well) has become mature...the things are light and with the switching power supply, they are light\
also, that technology is super insensitive to dirty power/line noise and basically no quiescent noise
which is really nice for something like Chapman stick where it's light touch - turn up the amp

they even put dwell on the reverb (though I'd wish they'd do the whole dwell-tone-mix like on the steelaire...which they killed)


anyway, didn't want to derail, but the basic class sounds similar

I bought a Yorkville EXM Mobile 8 a few days ago.
Awesome little unit, has the ability to run 5 hours on a lithium battery as well. Buskers dream. Loud and clean. Blue tooth on the third channel if desired. Tripod mounted.
If I could figure out how to post a pic I would, but I’m lo-fi.

Cheers,
Kev
