Covers the 1x12 Katana 100, the Artist and the head. The Artist, with its better speaker and cabinet, sits at the top.

Power on and play for 10 minutes - listen for crackle, hum or cut-outs
Every knob through its range, on every channel

Questions people ask about this model

Katana 100 or Katana 50: which is the better flip?

The 50 sells faster, to bedroom players. The 100 is loud enough for gigs, so it has a smaller but keener buyer pool and a higher price. Both are solid-state, with no valves to wear out.

Does this price cover the 2x12 version?

No. The Katana 100/212 is a bigger, heavier amp and sells separately. This page covers the 1x12 combo, the Artist and the head.

What should I check on a used Katana 100?

Every channel and effect, the power control at each setting, and the speaker for tears or rubbing. Test the effects loop and footswitch jacks too, because gigging amps get used hard.

Selling one on

Boss Katana, Fender/Marshall/Vox valve combos and Orange sell same-week. Big 4x12 cabs and 100W heads are slow and awkward. Small practice amps under £40 are barely worth listing.

Heavy - collection only for anything over 15kg. Valve amps do not travel well.

Where this price comes from

This is the range the flipper extension uses for a used Boss Katana 100 / Artist in working order in the UK. It is a starting point, not a quote: condition, extras, the original box and where you are all move the price, and faulty ones sell for much less.

The condition bands above are the same multipliers the extension applies to a listing. On a live Marketplace listing, flipper checks that range against real sold prices and live eBay listings for the exact model, works out your profit after fees and flags faults the seller mentions. It is free while in testing. Join the testers.
