About this app

The app opens a USB OTG connection to a Fender Mustang LT40S modelling guitar amplifier, or some other compatible device from the Mustang/Rumble LT range.

Once a USB connection is established, the application queries the amplifier to get details of the presets stored, groups those presets into suites according to which amplifier model each preset is based on, and presents screens to the user to allow rapid switching between the presets in a single screen/suite.

This application is only useful to users who own a Fender Mustang LT40S or other compatible amplifier. The user must also have an OTG-USB cable with a MicroUSB connector at the amp end and USB-C or MicroUSB (according to which the phone or tablet accepts) at the phone amp.

This is experimental software, and should only be run by users who accept that the software is not yet widely tested and that there is a slight (but non-zero) risk that the connected amplifier may be put into a bad state as a result of use of the software.

The source code for this application is available under the GNU Public License, version 2 or later from the following site:

Potential users with development skills are encouraged to build the software
from source and participate in the discussions at that site related to the capabilities of the software.
