AIRSTEP Kat EX Edition

"The Ultimate Foot Controller for KATANA Amp"

What Can It Do?

Hands-free switch channels, toggle effects, control effect types, and tap tempo, compatible with all KATANA models including Gen3, MkII & MkI.

Wireless tone editing via the BTS App for iOS & Android — no BT-Dual Adapter needed for Gen3, and the only wireless option for MkII and MkI.

2 expression pedal inputs for real-time control, assign functions freely in the BTS app.

Use alongside your GA-FC, exclusive GA-FC Expand Mode unlocks extra control.

Plug and play with zero setup. The best footswitch solution for every KATANA user — especially KATANA 50.

Advanced Control for Your KATANA

AIRSTEP Kat EX offers versatile hands-free control with Channel Mode for switching amp channels and Effect Mode for toggling effects, tap tempo, and effect types. Dual Press enables extra customizable functions, and the unique GA-FC Expand Mode allows it to work alongside the BOSS GA-FC, unlocking advanced control that the GA-FC alone can't provide. Whether or not you already own a GA-FC, Kat EX gives you more power and flexibility to control your KATANA amp.

Edit Your Tone Wirelessly, Anywhere.

With AIRSTEP Kat EX, you can wirelessly edit your KATANA settings anytime, anywhere using the BTS App — no need to connect to a computer. For Gen3 users, it works seamlessly with the KATANA Gen 3 mobile App or the third-party Katana Librarian app, without requiring the BOSS BT-Dual Adapter. If you're using a MkII or MKI model, you can use the KATANA-AIR App or Katana Librarian (recommended for full control).

Dual Expression Pedal Inputs

AIRSTEP Kat EX features two expression pedal inputs, you can assign them to control any parameter on your KATANA amp in real time — volume, wah, pitch, and more. Simply set your preferred function in the BTS App and shape your tone with your feet.

Unlock What GA-FC Can't

AIRSTEP Kat EX offers more power and flexibility than the GA-FC alone. If you already own a BOSS GA-FC Footswitch, combining it with AIRSTEP's GA-FC Expand Mode and wireless BTS App control unlocks the full potential of your KATANA amplifier — going far beyond what the GA-FC can do on its own.
