Pichtfactor question

Hi Guys,

I am the proud new owner of a Pitchfactor which I picked up on the fleabay. It's been working good but there is a strange issue that I can't seem to resolve.

The main use of my PF is to harmonize 3rd's intervals (similar to what Iron Maiden does). It does a pretty good job in alot of situations with this use, but there is one that I can't seem to fix. When playing individual notes that ring out (just one note at a time not chords) it sounds as if the harmonized note has a fake sounding distortion to it. The harmonized note sounds very fake and almost like it has a fuzz effect to it. What's odd is that with the same setting (same preset) if you play a palm muted riff it sounds pretty good – you cant hear the falseness. Now keep in mind I am not playing a million notes per second these notes are "ringing" out. Nor am I using excessive vibrato or artificial harmonics or 2 handed tapping techniques.

I bought the pedal mainly because of this video:

In the first minute and a half of playing he uses harmonized 3rd's and his sound (from the pedal) is pretty good and this is what I am after. The riffs I am playing are similar to what he is playing but my sound isn't similar to the video.

Quick description of my what my preset looks like:

Wet 50% (id like to hear both notes evenly)

Pitch Mix: A10 – B0

Pitch A -3d

Pitch B – Unison

Delay A & B – 0

X & Y knob – 0

Key is G Minor

Also I have tempo off if that matters (I don't use this feature).

My amp setup:

Guitar -> Pitchfactor -> Mesa boogie Dual Rectifier (ie run infront of the amp not through EFX loop).Yes, it is setup for Guitar as the source and for Guitar -> Amp on the flip switches on the backside of the pedal. Quick note about my guitar – It has EMG active pickups – and it has a mid boost. I have heard some pedals can overload with active pickups might this be the problem? Or am I using the preset in the wrong way?

Any advice is greatly appreciated. Thanks for looking.
