What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Boss Katana-50 Gen 3
Only one whitelisted tester, MusicRadar, published a hands-on review covering the Katana 50 Gen 3; it is positive but qualitative with no lab measurements. Praised for clearer, more detailed and more responsive tone and the new 'Pushed' voicing; the sole gripe is that Bluetooth is a paid optional extra rather than built-in. (1 sourced review.)
Praised: Clearer, more detailed and responsive tone versus the previous generation; New 'Pushed' voicing between Clean and Crunch became the reviewer's favourite; Familiar, easy-to-navigate control layout.
Flagged: Bluetooth is a paid optional extra (dongle ~£45) rather than built-in.
