This is a MIDI interface specifically for Carol-Ann Amps, and is designed to be an exact replacement for the original model they made. This interface will work with any Carol-Ann amp that has a 3-pin XLR footswitch jack and a 4 or 5 button footswitch.
The interface responds to MIDI program change (PC) messages, and changes channel, lead boost and fx loop based on the channel number. The interface comes set to channel 1 from our shop, but there's an internal switch that allows you to choose a different channel.
These are made one at a time by hand in our shop, so orders make take 1-2 weeks before they ship.
