Mooer F4 Wireless Footswitch Black for Mooer Intelligent Series

Great footswitch to control my Mooer PrimeP1 Multi Effects Processor. Took a bit of getting used to, to know which buttons to press to operate the controls (could have done with a User Manual that covered the Prime P1 details). But after watching several YouTube videos, from other users, I was able to piece together the many things that this pedal can do. There are four switches (A,B,C & D). Pressing each of these switches, in turn, scrolls up up and down the four saved guitar effects on the P1. Pressing A&B together scrolls up each of the ten sets of four saved effects. While pressing C&D together scrolls down the ten sets.
The best thing is, in pressing the B&C buttons together, this puts the P1 unit in to 'LOOPER MODE' that enables you to use the looper by foot control.
There are probably other great things that I have yet to discover. All-in-all, a very useful product.
