Guitar PCB Paramix – Signal flow and labeling review. Clarify?

Hi,
Not sure if folks are familiar with this one...
I'd like to represent the signal flow on the box itself, and I think I have some clear names for functions.
Wondering if anyone had feedback/corrections on my plan. This is my fold-over drilling guide, hopefully self explanatory.  If I understand correctly, kill is the same as cutting the send. And the T-diddy boost (100% wet) is the same as loop only/no direct. I tried to represent the I/O breaking of the direct as a dashed line. Question: the loop is returned after the I/O, correct?
Any feedback or suggestions? The layout is a bit dictated by physical constraints of the enclosure, so I actually put a lot of thought into clearing the jacks (not having the pots hit them, etc...) It would also be cool to know exactly where the phase switch is. I guess, in general, a block diagram of the Paramix would be really great.
Thanks in advance,

John

Looking at the schematic, yes, the loop return is mixed in after the in/out. This thing allows you to mix two separate paths, a bypassable effects loop and an "insert" in the other or "dry" path. Then the two are mixed.

The phase switch is on the return of the loop.



Your diagram has the order about right, with the detail that Direct Gain comes before Direct Volume.

Good point about gain before volume (doh!).
Any thoughts on my foot switch labeling? I'm trying to make things as clear as possible so that when I'm in spaghetti mode patching in pedals I can be solid on what is going on.

Thanks
