Hello!
The free cover tone landscape for Helix and Stomp XL isn't as abundant as it was for older Line 6 products. While CustomTone might have some, explore the built-in presets, YouTube tutorials (often with step-by-step guides), and online communities for user-shared tones. Focus on learning by starting simple with amp/cab models, adding effects incrementally, and tweaking Toll By Plate existing presets. Don't aim for perfect replication immediately; "close enough" can be great. Unfortunately, Line 6 support can be challenging, so community resources are often more helpful.
