Nice! Sometimes I see a guy named Justin Johnson come up on my YouTube playlists. I guess what he plays could be considered a resonator guitar:

Open tuning, like for the key of D would be D, A, D, F#, A, and D. Right? Sometimes we use what’s called a Dropped D on the guitar, but I very seldom do Open tunings.

Like Keith Richards does open G tuning to play Honky Tonk Woman. That’s cool. But I don’t think he’s using a resonator guitar.

I’m guessing you’re a musician, but this is the first I’ve heard of proaudio. I see they have a version for Ubuntu. I have the jack program or plugin whatever its called so it would work well with this desktop. 32GB of RAM, so that’s likely plenty. But I haven’t been playing much these last few years, so I probably wouldn’t need it or use it. I play guitar, and a little piano.
