Hi Joecozzi, thanks for the response.

The signal flow is  guitar >vol ped> wah> Gigrig G3 – – – then through loops>Tube Screamer1>Tube Screamer2>RAT Pedal> Xotic EP Booster>H9 Max>

>Strymon Timeline out to AMP.

I am using it for multi single note guitar leads, much like Brian May.

The sound I’m using is Quadravox in Pitchfactor.  For most of the time is sounds fantastic but occasionally a harmonised note is ambiguous and off key.

Thanks for any help!
