Meh, real amps sound better, but modelers just have that convenient factor.
Not gonna lie, a Boss Katana 50 and the bigger footswitch when really dialed in is so close to my blackstar artist 15 combo and pedalboard, it's scary.
The audience would never know, but I can, which is why I still use a vintage style low gain tube amp and analog effects to achieve the sound I like.
Half the fun is getting the sounds I really want, but if I were in a professional cover band playing every weekend, I would perform with a modeling amp at this point
Yes, I know the Katana isn't a true modeler, but it works just fine for that task. If you want to sound like the Rolling stones one song and then like Duran Duran the next, it's got you covered.
