I put together this quick suggestions list that might help newcomers to Linux who want to use Open Source tools for Guitars in their DAWs. Hopefully it will be useful to someone. Please let me know if you have any suggestions or additions. I'm quite sure it's not complete, and I haven't had time to test everything:
The Musician's (Not Programmer's) Starter Suggestions List for Open Source Guitar Amps/Cabs/FX
Criteria to be listed
Must: be open source, run properly, scale properly for HiDPI monitors (if using GUI), must have available linux binaries so that musicians (not just advanced computer users) can make use of the tools
The general idea of all of this is to be able to either use Guitarix.vst and load all of these additional plugins into it to supplement what it comes with, or to create your chain of plugins straight from within your DAW and manage them from there. Either way works! Here are the suggested plugins:
Pretty much everything by brummer10--especially: Guitarix.vst (JUCE port of Guitarix wrapped for VST3) comes with tons of amps, cabs, & effects!), GxPlugins.lv2 (comes with even more effects!) ImpulseLoaderStereo.lv2, ImpulseLoader.lv2, StompTuner, ToneTwistPlugs (Comes with several effects)

Ildaeil: ( https://github.com/DISTRHO/Ildaeil ) A mini plugin host as a plugin. This tool can be used to load plugins incompatible plugins into your guitar chain, whether that be hosted in Guitarix.vst or from within the DAW itself. Essentially, this is a "Wildcard" secret weapon plugin to allow you to use any effects of the following types: LADSPA, DSSI, LV2, VST2, VST3, CLAP, JSFX within your guitar plugin chain.
NOTE: There are MANY, MANY more available plugins that should work along with the above listed plugins. This is just some great suggestions to get you started.
