I'd like to Ask The Audience something.
I'm in the process of putting together a loop pedal with a blend control... having experimented in the past it appears that certain pedals have a phase inverting tendency, so I want to be able to work round this if possible with a switchable phase inverter. However, I'm a little uncertain as to where the inverter should go. I'm thinking it would be example A below, but I want to make sure.
