Designed to work with the following amps: ID:15TVP, ID:30TVP, ID:60TVP, ID:60TVP-H, ID:260TVP and ID:100TVP The FS-10 is a multi-function footcontroller that allows access to all 128 patches plus the tuner function. It operates in three modes: Effects mode ? This offers individual switching of the effects within a patch, operating more like traditional effects pedals. In this mode the fourth switch is used to control the tap time function. 8. Navigation mode ? Enables access to the complete set of 128 patches stored on the amp. These can be stepped through one at a time, or in banks. Whilst in this mode you can also store patches. Patch Mode ? This mode allows you to switch between the three banks of four patches accessible on the front panel of the amp (patches 1-12) in addition to patches 13-128, plus access to the tuner function and the ability to change to the other modes.
