It's "stereo" in that there are two amp outputs. Signal flow is now:
Left (A) Channel - Visual Volume -> EHX Neo Clone -> EHX Soul Preacher -> Barber Burn Unit EQ -> Liverpool Deluxe -(efx loop)- M-Audio Black Box -> Morley Twin Mix -> Radial D2
Right (B) Channel - Visual Volume -> EHX POG 2 -> EHX Big Muff Pi with Tone Wicker - > Custom Tones Ethos -> Morley Twin Mix -> Radial D2
The Radial D2 is attached to the bottom of the Pedal Train Pro, where the Voodoo Lab Pedal Power 2 would normally go.
