The Boss Katana-50 MkII for an Experienced Guitar Player

Even though I don’t own this amp, I have played it and think its outstanding. I still own an inexpensive modeler (NUX MG0-30) as well as amp plugins. This allows me to test some different sounds and record songs using amp models that match the gear that was used to record songs that I’m covering.  This amp can essentially do the same thing, but comes in a combo amp platform.  I’m normally just playing my modeling gear through my PC or running into an amp and cab using the 4 cable method.  But if I wanted an all in one package, I wouldn’t hesitate.

Got my first guitar in 1987, took lessons and played nonstop. Spent some time in hard rock and metal bands in the 1990s. I eventually switched to acoustic guitars only and rarely played for years. I got back into electric guitars when my daughter began playing in 2018. I now collect way too much gear.
