Store and edit patches on your Katana amplifier directly from your phone or tablet!

The BOSS Katana series are terrific amplifiers. Unfortunately they only have the ability to store up to 8 patches on-board. The only way you can access more than 8 patches is hook your amp up to a PC or Mac and install the BOSS Tone Studio application. In addition many of the amplifier effects are only accessible through the PC application.

Until now.

Introducing Katana Librarian. Simply attach your Android phone or tablet to your amplifier using a USB On-The-Go adapter and you can switch between patches and edit them right from your device.
