Boss Katana 50: A Complete Buyer's Guide
Boss Katana 50 now covers three generations. Here's exactly what to check before you buy, new or used.
Buying a Boss Katana 50 isn't complicated, but it's worth doing properly, because "Katana 50" now covers three distinct generations with real differences between them. Here's what actually matters before you hand over any money, whether you're buying new or hunting secondhand.
Which Generation Should You Buy?
If you're buying new, this is simple: you'll be getting the current Katana-50 Gen 3, which adds USB-C connectivity, Boss's Bloom response circuit and a slot for an optional Bluetooth adaptor over the older MkII. If you're shopping used, all three generations turn up regularly, and the practical differences are worth knowing:
| Generation | USB type | Key feature |
|---|---|---|
| Original | USB-B | Base Katana concept, fewer amp variations |
| MkII | USB-B | Power Amp In, cab-emulated recording output |
| Gen 3 | USB-C | Bloom circuit, Bluetooth adaptor slot |
A used MkII at the right price is still a genuinely solid amp; don't assume it's automatically the wrong choice just because it isn't current.
New Versus Used: The Real Trade-Off
There's no single right answer here, only what actually suits your situation. New buyers get a full warranty, current firmware and no unknown history — sensible if you're relying on this as your only amp for gigging or regular rehearsal. Used buyers can often find an MkII or even an original Katana-50 for meaningfully less money, which is a perfectly sound choice as long as you go in with your eyes open about which generation you're actually looking at. The underlying concept hasn't changed dramatically across the three generations, so you're rarely buying a fundamentally worse amp, just an older feature set.
Specs That Actually Matter When Buying
- Power control — every generation offers reduced-power settings for practice, but confirm which stages are available before assuming it'll suit a quiet flat.
- Speaker size — a genuine 12-inch speaker, not the smaller full-range drivers found in compact practice amps. This is a big part of why it sounds and feels like a proper amp.
- USB connection type — USB-C on Gen 3, USB-B on the MkII and original. Worth checking if you already own the cable, or need to budget for one.
- Effects loop / Power Amp In — useful if you plan to run a separate preamp, modeler or pedalboard into the Katana's power section.
New or Used: What to Check
Buying new means a warranty, current firmware, and no guesswork about condition — sensible if this is your only amp. Buying used is a genuinely reasonable way to save money on a design that hasn't fundamentally changed its core concept across generations, but check a few things before you commit:
- Confirm the exact generation (original, MkII or Gen 3) rather than trusting a vague listing title
- Test every amp type and the power control switch, since these are the parts most likely to show wear on a well-used unit
- Check the speaker for any tears, rattles or scorching around the cone
- Ask whether the original footswitch or power cable is included, since replacements cost real money
Boss Katana 50 vs the Competition
Two amps come up constantly in the same conversation: the Positive Grid Spark 2 and the Line 6 Catalyst. The comparison isn't really about which is "better" — it's about which approach suits how you'll actually use it.
| Amp | Approach | Best suited to |
|---|---|---|
| Boss Katana 50 | Traditional amp panel, deep software editing available | Players who want a proper guitar-amp feel first, extras second |
| Positive Grid Spark 2 | App-based modeling and practice tools | Players who want jam tracks, tone matching and app-driven learning |
| Line 6 Catalyst | Amp-style front panel with modeling depth | Players comparing directly against the Katana's format |
What Else You'll Need
Most Katana 50 purchases don't need much extra kit, but a few things are worth budgeting for: a USB cable matching your generation if you plan to record, an optional footswitch if you want to switch presets hands-free on stage, and the optional Bluetooth adaptor on Gen 3 models if you specifically want wireless audio streaming or MIDI — it isn't included as standard.
It's also worth thinking about where you'll actually use it. A genuine 12-inch speaker moves considerably more air than a small practice combo, which is a real advantage at rehearsal but can feel like overkill in a small bedroom — not because it's too loud at full volume, but because you'll rarely need the amp on the floor pointed straight up at your knees. Raising it toward ear height, on a stand or a sturdy shelf, makes a noticeable difference to how balanced it sounds at any volume.
Making the Decision
Buy new for the current Gen 3 feature set and full warranty; buy used, generation confirmed, if the saving is worthwhile and you're comfortable checking a secondhand unit properly.
