HX Stomp XL: Connect a mic and an electric violin in Helix Posted March 30, 2021 Seems that what you propose should work. Give it a try. You may need to adjust the level inputs to accommodate your Mic and Violin signal levels. Are you also planning to connect a Guitar. BTW, I do not have the XL. I have the HX Stomp. Post back your findings to share what works for you with others whom may be following this thread.
