Don’t count out separates. More expensive? Maybe,
Not as
Much as you think. I bought a SWR 12” “Monitor” kickback cab for $100. It’s better than the WM series. And a TC electronics head $250. Played it for a few years. I got all kinds of compliments on the sound. I recently brought that setup to my restaurant gig. The guitar/singer said it sounded much cleaner than my Rumble 100. If you are able to move a cabinet around 40 lbs, there are plenty of great cabinets available. Some boutique brands like efiphani. Me? I am not exactly young and weight is now a factor. Now, the less the weight the more the cab costs.
To me, it’s easier to get a good sound from separates than a combo. Plus you can easily carry a backup head. But, I sometimes still take my rumble 100 to my gig. Too easy to grab & go.
