Voodoo Lab Ground Control Pro

I use this pedal MIDI since 2011 to control my Mark V. Very strong and easy to program, it is used a lot of pro.

No trouble with this equipment, you need to buy.

for the price, there is no better, he's the main functions that may apply to a pedal. on the other hand no editor PC / MAC, which can make the prog rather tedious for some.
I would do not buy this because its switch is not reliable enough, sometimes you have to try several times to change sounds. Indeed, the PCM does not integrates real mechanical switches such as competition, it is actually switch CMS soldered to the board that will soon have a tendency to clog. Over time, operate the switches becomes increasingly dangerous, once it works, once it does not work, and live I can not tell you the anguish.
