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

The Boss Katana-50 Gen 3 packs evolved Tube Logic technology and a genuinely deep amplifier voice library into a compact, portable 50-watt combo built around a custom 12-inch speaker. Six distinct amplifier personalities — including Gen 3's new edge-of-breakup Pushed voice alongside Katana classics Clean, Crunch, Lead, Brown, and Acoustic — each include a tonal Variation, adding up to 12 total amp voices. Five independent effects sections deliver a library's worth of classic stompbox-inspired reverbs, delays, and modulation, while a powerful 3-band EQ, four Tone Setting memories, Power Control for cranked tone at any volume, and the upgraded BOSS Tone Studio app round out a feature set that punches well above its compact size and weight. Perfect for practice sessions, home studio setups, and casual gigging, the Katana-50 Gen 3 is ready to be the centerpiece of any rig that doesn't need full stage volume to sound great.

Product Overview

Evolved Tube Logic technology is the foundation of the Katana-50 Gen 3's tonal character — BOSS's approach to recreating the dynamic feel and response of real tube amplifier circuits rather than simply matching their frequency response on paper. This translates into an amplifier that responds to pick attack, playing dynamics, and volume changes the way a genuine tube amp does, addressing the responsiveness gap that has historically separated modeling amps from their tube counterparts. Six amp voices span clean to extreme: Clean offers pristine headroom, Pushed is new to Gen 3 and delivers the dynamic edge-of-breakup character favored by blues and classic rock players, Crunch and Lead handle rock and metal rhythm and lead tones, Brown provides high-gain saturation, and Acoustic models an acoustic-electric guitar tone through an amplified signal. Each voice includes a Variation accessible via a quick press of a dedicated switch, doubling the effective amp count to 12 distinct tonal options.

Five independent effects sections, modeled directly after BOSS's own stompbox pedal designs, provide deep onboard access to spacious reverbs, ethereal echoes, and a range of modulation effects — eliminating the need for a separate pedalboard for players who want comprehensive tonal coverage from the amp alone. A powerful 3-band EQ along with Presence and Contour controls gives players precise tonal shaping capability across the full frequency spectrum, and four Tone Setting memories allow favorite amp and effect combinations to be saved and instantly recalled — useful for quickly switching between distinct tones for different songs or sections during a practice session or performance.

Power Control is one of the Katana-50 Gen 3's most practically valuable features for home and studio players — it scales down the amplifier's output, making it possible to access fully cranked, driven tones at volumes appropriate for bedroom practice or apartment living, rather than requiring loud stage volume to push the amp into its ideal tonal sweet spot. A cab-sim-equipped stereo headphone jack and USB-C output support silent practice and direct studio recording with realistic cabinet simulation built in, and an optional BOSS BT-Dual Bluetooth Audio MIDI Dual Adapter (sold separately) adds wireless access to the amp's editing and streaming capabilities. The upgraded BOSS Tone Studio app delivers an enhanced UI and improved editing tools for deep tonal customization and Tone Setting management from a connected computer or mobile device.
