Not sure if you saw this or not, but this is the updated modulation layout. Its much more clear.
I have since changed a few things on mine. I wired mine so that the LFO is grounded when the pedal is bypassed. I was getting some ticking bleed in the ground when using fuzz pedals with it. Grounding the LFO cured it beautifully.
I also couldn't decide how I wanted the detune switch to be, so I used both momentary and fixed. Momentary stomp and a fixed toggle (w/ LED indicator for the toggle).
I find the detune pot of the modulation board very nice. You can detune the pitch very precisely to a specific pitch.
I LOVE this looper.
