Five buttons to make your looping life easier. The 45000 Foot Controller gives you the ability to select the track you record on with a track select switch and a record and play footswitch. You can also switch up and down between stored loops and gives you a display of the up to 100 loops you can recall from your SD card. The FC45000 also receives power from the 45000 and connects to the 45000 with a simple mono instrument cable.
