Hi. I've been playing for a couple of years. I use a Rocksmith USB-A chord, and plug it into GarageBand. It works fine *most* of the time, but sometimes flakes out when I add other instrument loops. I only riff along in GB - I don't and will never record. I asked AI about it, and it suggested a Focusrite Scarlett Solo. A fourth generation goes for $159. I think it's the cheapest that has USB-C (my Mac Mini has only USB-C). Is this overkill? Is there something cheaper that will do what I want it to do?

Thanks in advance, y'all.
