I am putting this in the modeling section because the info these guys discuss is easily applied to my patch building in the Helix, and probably other units as well. https://www.youtube.com/channel/UCnUXq8mGmoHt0e6ItuTs10w I never really messed around too much with pedals. Boss DS-1 and a compressor were the only pedals I have ever owned. My lack of experience with delays, fuzz, EQ, wah, etc really held me back when I got my HD500X a couple years ago. I got better through trail and error, but still was at the novice level. These guys are brilliant. I have watched most episodes over the last 2 months and I am hooked. For example, I never liked fuzz AT ALL. After watching their fuzz video, I applied what they discussed to the Helix and now I have a fuzz patch that I actually use in my cover band. I never would have even tried fuzz without these guys. Anyway, check them out if you're so inclined.
