I'm a more recent convert in the modeling space. The simplest reason I use it now is I'm not currently playing out so modeling affords me all the things I love about guitar tones in an easy to use package. I can play quietly if needed, and recording with it is a breeze, yet gives me endless possibilities to craft tone ideas. What's not to love? I still enjoy tube amps and pedals but my goal is to play as much as possible in my current musical journey, and modeling fills that need perfectly.
