The Helix has a very good global EQ - and a number of other very good EQ “blocks” - it has a Mic in and I’ve recorded vocals through it very successfully - it’s certainly not limited to guitar and bass
Dunno whether it’s gas or not.. don’t get me wrong, I’ll be mostly gigging frfr - but I can see this stack getting a few outings when I really want to give it some..
The only Ampeg combo that ever really impressed me was one of the “T” models with a tube preamp - but even that was low output.
I would suggest something with more heft and power as well. If you can stand the weight you can get some seriously powerful Trace watts for buttons these days..
Well, let’s just say that I paid significantly under 1/10th of that for mine.. ok, it needs a service, but it cost more in diesel than it do to pay for it....
