For an all-in-one playing experience that encompasses sounds from a crunchy '80s metal amp to weird and wild modulation effects, the Boss Katana-50 MkII Digital Modeling Combo is a solid pick. Five amp voices from Clean to Crunchy to Brown (think EVH's arena-sized sound) are on tap alongside five authentic onboard Boss effects from reverb and delay to distortion and modulation in a package that has enough punch to handle its own on a stage.
