I use it in "Favorite" mode for a second time on my sound Brigadier. It is practical, sturdy, not too expensive, and it does not take up much space on a pedalboard. It only works with a stereo cable.
I have not found it very simple function to save his favorite at first but once you understand, do not worry. It can be used in "Tap Tempo" (a kind of internal switch not very practical) and all other pedals that have an "EXP" input a priori.
For information, I tried to use it as a switch to change channels on an amp, it does not foncitonne. Too bad, it would have been perfect.
