Boss Katana-50 EX Gen 3 50-Watt 1x12" Guitar Combo Amplifier – Black | No Limit Guitar Co, Idaho Falls


The Boss Katana-50 EX Gen 3 is a supercharged spin on the standard Katana-50, borrowing a host of pro-grade features from its larger Katana Gen 3 siblings while keeping the grab-and-go portability that makes the Katana-50 series so popular. This 50-watt, 1x12" combo adds a cab-sim-equipped Line Out and USB out, full compatibility with BOSS's optional GA-FC/GA-FC EX foot controllers, and an upgraded speaker on top of the same six amplifier personalities — including Gen 3's new dynamic edge-of-breakup Pushed voice — found across the Gen 3 lineup. With a Variation switch unlocking 12 total amp tonalities, five independent stompbox-inspired effects sections, a powerful 3-band EQ, four Tone Setting memories, and Power Control for cranked tone at manageable volumes, the Katana-50 EX Gen 3 is primed for live performance and a must-have for gigging guitarists who want dynamic, tube-inspired tone and classic BOSS effects in a portable package.

Product Overview

The "EX" designation on this Katana-50 reflects a meaningful upgrade path over the standard Katana-50 Gen 3 — while both amps share the same evolved Tube Logic technology, six amp voices, and five effects sections, the EX version adds professional features specifically aimed at gigging guitarists. The cab-sim-equipped Line Out is the most significant addition — providing a dedicated, cabinet-simulated direct output separate from the headphone jack, ideal for running directly into a PA system, mixing console, or recording interface without requiring a separate microphone on the amp's speaker. This is a feature typically reserved for higher-tier amplifiers, and its inclusion on the Katana-50 EX makes the amp considerably more useful in venues and recording situations where a direct, professional-quality signal is needed.

Full compatibility with BOSS's optional GA-FC and GA-FC EX foot controllers is another EX-specific upgrade that distinguishes this amp from the standard Katana-50. These foot controllers unlock comprehensive hands-free control over channel switching, effects engagement, and other amp functions during live performance — a meaningful upgrade for gigging guitarists who need reliable, foot-operated control without reaching for the amp's front panel mid-song. The upgraded speaker contributes to the EX's overall tonal performance, working in tandem with the same evolved Tube Logic technology found across the Gen 3 lineup to deliver dynamic, valve-inspired response to playing dynamics and pick attack.

Beyond these EX-specific upgrades, the Katana-50 EX Gen 3 shares the core feature set that makes the Gen 3 lineup so capable. Six amp voices — Acoustic, Clean, Pushed, Crunch, Lead, and Brown — each include a Variation accessible via a dedicated switch, providing 12 distinct tonal starting points from pristine clean headroom to high-gain saturation. Five independent effects sections, modeled after BOSS's own stompbox designs, deliver a library's worth of reverb, delay, and modulation options directly onboard. A powerful 3-band EQ with Presence and Contour controls provides precise tonal shaping, four Tone Setting memories allow favorite amp and effect combinations to be saved for instant recall, and Power Control scales the amp's output down to access fully cranked, driven tones at volumes appropriate for smaller venues or practice spaces. An optional BOSS BT-Dual Bluetooth Audio MIDI Dual Adapter (sold separately) adds wireless access to the amp's editing and streaming capabilities, and the upgraded BOSS Tone Studio app delivers an enhanced UI and improved editing tools for deep tonal customization.

Ideal For

  • Gigging guitarists who want a portable Katana combo with professional direct-output capability for PA and recording situations

  • Performers who want onboard reverb, delay, and modulation effects without assembling a separate pedalboard
  • Recording musicians who need a cab-sim-equipped Line Out and USB-C for direct, studio-quality recording
  • Guitarists in Idaho Falls looking for the most performance-ready version of the Katana-50 Gen 3, built for grab-and-go gigging with pro-grade connectivity
