Boss Katana-50 MkII EX - 50W Guitar Combo Amplifier (Used)

The Wanderkauven Take The Boss Katana series changed the game for modeling amps, and the Katana-50 MkII EX takes it a step further. This isn't just a bedroom amp; it's a legitimate performance tool.

What makes the "EX" model special? It finally adds support for the GA-FC and GA-FC EX Foot Controllers, a feature previously reserved for the larger 100-watt models. This means you can change channels and toggle effects on the fly with a pro-level pedalboard setup. It also features a dedicated Line Out, making it perfect for sending your tone directly to the front-of-house PA without needing a microphone. With 50 watts of power pushing a custom 12-inch speaker, it has plenty of volume for club gigs, but can also scale down to 0.5 watts for late-night practice. It covers everything from sparkling cleans to high-gain metal with ease.
