All user reviews for the EMG Pi2 Phase Inverter

C is a phase switch, microphone active (9V battery)
s use of a microphone / or all

I used the microphone on the middle of my strat
c is that it is best for me
tb's in position 2 and 4 out of phase with the neck pickup and bridge

the best is still a 1 ft2 each microphone to a wider range of its

but the c is more expensive

I fed the same pile with my emg's 3
and not more consumption of battery, not greedy at all
