The Fender cabs are your best bet as far as cost goes. Everything else is pricey $$. But you do need something other than the Headrush. And keep in mind that whatever you replace it with is still FRFR so even though it will sound better, it’s still not amp in the room tone. Some people just run an amp into a guitar cab because FRFR doesn’t work for them. I’m kind of used to it now and I’m running an amp into a Celestion F12 cab which was a huge improvement over the Headrush 112 I was using. I’ll be buying a Fender cab myself soon. For variety and stereo and lighter carry. And as always I am amused because even though you described your whole situation and budget, people still recommend the big money options.
