Hi Guenti
I have no problem with drop tuning a 1/2 step with presets 22:1 and 24:1. or any pitchflex preset. I use the PF in front of two amps in stereo. The only way I can hear the standard pitch is if a turn the amps voulme down really low, I can then hear the guitar's standard pitch acoustically.
Do you have both the heel (pitch A knob) and toe (X knob) for pitch A set to -m2?
A
