At ToneLib they have experimental Linux (Ubuntu build, can't find link to source files) software available mostly for guitarists.

Did open ToneLib GFX and ToneLib JAM, needs work, doesn't really work on PulseAudio, have to try with Jack.
ToneLib Zoom is working flawless on my Pop!_OS install. Really plug and play on my Zoom G3Xn (get one while they are still available!! Really nice as an under the desk quick fooling around thingamajig). No need to bend down anymore to change some settings.
Just thought I share. Cheers!
And now I need a solution for BOSS TONE CENTRAL!
