BOSS Katana-100 Gen 3 100W 1x12 Modeling Guitar Amplifier

BOSS Katana-100 Gen 3 100W Modeling Combo Guitar Amplifier

The BOSS Katana-100 Gen 3 guitar amplifier combines 100 watts of reactive Class AB power with a custom 12-inch speaker, evolved Tube Logic technology, and extensive onboard tone shaping. Six amplifier characters with selectable variations provide 12 core voices, while five independent effects sections support practice, recording, rehearsal, and stage performance.

The Acoustic, Clean, Pushed, Crunch, Lead, and Brown amp types cover everything from clean instrument amplification to saturated high-gain sounds. Players looking for a 100W guitar combo for live performance, a 1x12 modeling amplifier for recording, or a Katana amp with an effects loop also get eight Tone Setting memories, Power Control, three Contour settings, and selectable cabinet resonance.

USB-C supports computer and mobile-device recording, while the line and stereo headphone outputs use IR-based cabinet sound with selectable Air Feel settings. Stereo Expand links a second compatible Katana amplifier, and the send/return loop integrates external effects. The GA-FC and GA-FC EX foot controllers are supported, while the optional BT-DUAL adapter adds Bluetooth audio and wireless mobile editing.
