BOSS Katana-50 EX Gen 3 50W 1x12" Guitar Amplifier: The Next Generation of a Modern Classic

With Katana Gen 3, the acclaimed BOSS stage amplifier series evolves to take your guitar ambitions to the next level. New Tube Logic enhancements enrich the core platform with even greater sound, feel, and response, including an expressive Pushed amp character that edge-of-breakup fans will love. The BOSS Tone Studio app has also been updated, making your remote amp and effects editing workflow more intuitive than ever. Loaded with inspiring tone tools and diverse connectivity options, Katana Gen 3 is your indispensable centerpiece for studio recording, live performance, and daily practice.

Enhanced for Live Performance

The Katana-50 EX Gen 3 model extends the core features of the Katana-50 Gen 3 with enhancements for live performers. Additions include an upgraded speaker, Line Out and Stereo Expand functions, and GA-FC/GA-FC EX Foot Controller support. This 50-watt combo amp with a custom 12-inch speaker is designed for stage performance, delivering robust and dynamic sound.

Comprehensive Tone Shaping

This amplifier offers six amp characters—including the newly developed Pushed type—plus a selectable variation for each, providing a wide range of tonal options. The five independent effects sections (Booster, Mod, FX, Delay, and Reverb) allow for extensive sound customization. Four Tone Setting memories let you store all your amp and effect settings for quick recall during performances. The Power Control feature enables you to achieve cranked-amp tone and response at low volumes, making it perfect for any playing environment.

Versatile Connectivity

The Katana-50 EX Gen 3 is equipped with a variety of connectivity options to suit your needs. The Power Amp In is ideal for preamps, modelers, and multi-effects, while the Stereo Expand function allows you to link with a second Katana amp. The stereo headphones jack, line output, and USB output with IR-based cabinet sound make recording and silent practice easy. You can record and play tracks in music production software on a computer or mobile device via USB-C.

Customization and Expansion

With jacks for up to two footswitches and an expression pedal, the Katana-50 EX Gen 3 can be expanded to meet your performance needs. The optional Bluetooth® Audio MIDI Dual Adaptor (BT-DUAL) allows for wireless audio playback from a mobile device and remote editing from the BTS app. The newly updated BOSS Tone Studio interface offers a more intuitive workflow, letting you customize the onboard effects with over 60 premium BOSS types and detailed editing tools.
