Help with amps

So I’ve recently gotten a boss katana mk2 50 watt and I’ve kinda been left wanting. For some reason the tone studio refuses to connect to my amp even after following all instructions and the general tone im getting from doesn’t sound great (this could also be because the guitar I currently have is cheap and the strings are fairly old but I’m having them changed soon). I bought with the intention of playing stuff like nirvana and pierce the veil but I’m considering returning it, is there a better amp at a similar price that will give me this tone?
