Pre-Owned Boss Katana KTN-50 Gen 3 50W 1x12 Guitar Combo Amp with Cover (Excellent Condition)

Pre-owned Boss Katana KTN-50 Gen 3 50-watt guitar combo amplifier, complete with protective cover. This amp is in outstanding “as new” cosmetic condition — no marks, as it’s been kept covered when not in use.

This is the Generation 3 Katana design (Katana-50 Gen 3), which is the latest evolution of Boss’s stage-ready Katana series. Gen 3 features updated Tube Logic processing for even more responsive, valve-style feel, plus new voicings and an improved control layout compared to earlier Katana versions.

You get a proper 50W output into a custom 12" speaker, six core amp characters with a new “Pushed” edge-of-breakup tone, onboard Boss effects, Power Control for quiet playing, four recallable tone memories, and USB / headphones out with cab emulation for direct recording.

Pre-owned item. Excellent condition. Includes fitted amp cover.

Key Features

• Generation 3 Katana platform
  Third-generation Katana circuitry with evolved Tube Logic for more tube-like response, dynamics, and feel under the fingers.

• 50-watt 1x12 combo
  Stage-capable 50W combo with a custom 12-inch speaker. Plenty of volume for rehearsal and small gigs, not just bedroom levels.

• Six amp characters + variations (12 total voices)
  Clean, Crunch, Lead, Brown, Acoustic, and the new Gen 3 “Pushed” voice for that edge-of-breakup, just-breaking-into-grit sound. Each character also has a Variation, giving you 12 distinct amp tones onboard.

• Five independent effects sections
  Booster, Mod, FX, Delay, and Reverb are all built in, with access to 60+ classic Boss effects and deeper editing via the updated Boss Tone Studio app. You can run multiple effects at once — it behaves like a mini rig, not just an amp with “a bit of reverb.” 

• Four user memories (“Tone Settings”)
  Store full amp/effect setups and recall them instantly. Great for rehearsal sets or switching sounds mid-song without a pedalboard.

• Power Control for home use
  Built-in Power Control lets you dial the wattage down so you can get driven-amp feel and saturation at low volume.

• Direct recording and silent practice
  USB and stereo headphones/recording outputs include cab simulation, so you can record straight into a DAW or monitor silently without miking the speaker.

• Boss Tone Studio (Gen 3)
  The latest Boss Tone Studio software gives deeper editing, colour-coded effect sections, and access to Boss Tone Exchange to download/share patches. Gen 3 also supports optional Bluetooth editing/control with the BT-DUAL adapter.

• Condition & extras
  Pre-owned, excellent. No cosmetic marks. Includes protective cover, which has helped keep the amp clean.

Why Choose This Amp

Katana has kind of become the standard “does everything” guitar combo. Gen 3 improves on the older Katana versions with more touch sensitivity, the new Pushed voice for that classic edge-of-breakup feel, and better onboard control of effects and tone shaping.

In practice, that means:

• Loud enough for a band room or pub gig (50W into a real 12" speaker).

• Quiet enough for late-night playing using Power Control and headphones.

• Ready to record over USB with cab sim, no mic needed. 

Because this unit is pre-owned but in “as new” condition and already comes with a cover, it’s a tidy way to get the Gen 3 version without paying for a brand new one.
