Guitar World Verdict

Boss hasn’t tried to completely reinvent its popular practice amp line – because it didn’t need to. Katana 50 MKIII keeps the same great aesthetic, usability and spirit of the original while pushing the series forward with upgraded tones and functionality.

The name Katana always felt like the perfect moniker for this cutting-edge practice amp. This feature-laden combo sliced through its competition when it hit the market in 2016 and became one of the best-selling amps in recent memory. New for 2024, Boss has revamped the series for its third generation, boasting improved sound quality, a brand-new “pushed” amp model and an enhanced feature set – but can it live up to the hype of the previous versions? 

While the entire Katana range is receiving the Gen 3 treatment, only the 50, 100, and 100 212 models are available to purchase at launch. Today, we'll examine the Katana 50 MKIII to see how it compares to the prior generation.
