Katana Librarian
Important: Katana Librarian is developed and supported by Apps For Amps.
Juca Nery Guitar is not the app developer. I collaborate with the developer and provide some of my own patches for the app.
For technical support, feature requests or app-related questions, please contact:

Katana Librarian allows you to connect your phone or tablet to your BOSS Katana amplifier via USB or a Bluetooth adapter (sold separately), unlocking your ampโs full potential!

The free version includes a selection of Juca Nery patches, provided through my collaboration with the app developer.

Katana Librarian
The free version of the app allows you to test your connection and load the built-in demo patches. A one-time in-app purchase is offered if you wish to unlock the full feature set, which will allow you to:
– Download patches from your amplifier.
– Modify the patch parameters; includes support for all effect types; the editor also changes in real-time as you adjust the parameters on your amp.
– Organize your patches into groups. Tag your favorite patches, or create a set list for a live performance.
– Import and export MkI, MkII, Gen3 and GO .TSL files.
– Rename and delete patches.
– Write patches to the amplifier’s channels.
– Emulate the functionality of a GA-FC pedal (even on a KATANA-50 or KATANA:GO).
– Use the hotkey feature in combination with a Bluetooth MIDI or HID foot switch (e.g. https://amzn.to/3RqNcDY) for hands-free patch and effect switching.
– Access undocumented Katana features like hidden amps and multiple simultaneous effects (where available).
