Boss KTN-502EX Katana MKII EX 50W 1x12" Guitar Combo Amplifier

The Evolution of a Modern Classic

The Boss KTN502EX Katana MKII EX 50W 1x12" Guitar Combo Amplifier takes the acclaimed Katana guitar amp series to the next level, turbocharging the core platform with more sounds, more effects, and more features. Cover any style with five amp characters and five variations. These variations offer everything from organic vintage tones to modern high-gain sounds, plus a dedicated voice optimized for acoustic-electric guitar. Each character also includes a selectable variation, providing a broad palette of tone options to craft your personal sound. BOSS Tone Studio takes the Katana MkII experience even further, allowing you to customize the amp for your style and touch. Change up the factory-loaded effects, adjust effect order, shape the overall tone with global EQs, tweak the cab resonance, and much more. And with Livesets, you can save favorite setups and instantly reconfigure your Katana MkII for different playing situations.

All Katana MkII models feature five simultaneous effects categories, putting the tone-shaping power of a massive pedalboard right inside your amp. Independent Booster, Mod, FX, Delay, and Reverb sections come loaded from the factory with three variations in each, providing 15 ready-to-play effects to choose from. Connecting to BOSS Tone Studio lets you dive much deeper if you want - customize the sections with over 60 different effect types, change the order with four different chains, and much more. Backed by BOSS’s Tube Logic approach, Katana MkII delivers the authentic output distortion characteristics of genuine tube amplifiers, with the sound and feel becoming richer and more responsive as you turn up the volume. But unlike classic tube amps, Katana MkII’s variable Power Control makes it easy to fly in the sweet spot without getting fired from the gig or kicked out of the house. Just throttle back the overall volume as needed to enjoy inspiring, cranked-amp sound anywhere you play, from bedroom to stage.

The Katana-50 MkII EX rocks as a standalone amp, but it also excels as a powered cabinet for a favorite preamp, modeler, or multi-effects unit. Connecting to the rear-panel Power Amp In jack bypasses the onboard preamp and effects, letting you tap straight into the Tube Logic power section, complete with grab-and-go Power Control. And with BOSS Tone Studio, the input can be easily optimized for your particular gear with a high-pass filter and adjustable gain. One Katana MkII sounds great—but playing two at once is even better. The Stereo Expand feature makes linking two amps simple, with just one regular cable needed. You can control everything from the main Katana MkII, with stereo-compatible effects like chorus, delay, reverb, and others distributed across both amps for a wide, immersive sound field. Stereo Expand is supported on all Katana MkII models except the Katana-50 MkII. The Katana-50 MkII EX also features line, USB, and phones/recording outputs with mic’d cabinet emulation, letting you send mix-ready amp tones to a PA system, computer DAW, or headphones. The direct sound can be shaped with three different Air Feel settings, which are accessible from BOSS Tone Studio. Two-channel USB operation is supported, allowing you to track in true stereo with many of Katana’s modulation, EQ, delay, and reverb effects.

One of the Katana MkII’s most powerful features is the ability to store favorite amp character and effects setups in Tone Setting memories for instant recall. After you’ve dialed in a sound with the controls, simply save it to the desired memory with a quick button hold. Four Tone Settings are available for fast selection from the panel or optional FS-series footswitches. The optional (sold separately) GA-FC and GA-FC EX offer expanded foot control, giving you access to eight Tone Setting memories (four panel settings plus four configurable in BOSS Tone Studio). These footswitches connect with a single cable, require no external power, and take up minimal space. With six footswitches, you can directly recall Tone Settings and independently turn the five effects sections on/off. They also support external footswitches and expression pedals, with customization via BOSS Tone Studio. The GA-FC offers standard control, while the expanded GA-FC EX provides the ability to control two amps together, connect another unit for additional foot control, and more.

At Riffs & Licks Music, we think the Boss KTN502EX Katana MKII EX 50W 1x12" Guitar Combo Amplifier makes a great addition to virtually any setup; this versatile genre-spanning amp is equally comfortable on-stage, in-studio, and at home
