Help Needed - Schematics deciphering

[holm]

Hi
I've decided to build the BAJA 59 Tweed Bassman pedal by Bajaman over at freestompboxes.
http://www.freestompboxes.org/viewtopic.php?f=13&t=28915&hilit=bajaman+bassman

However, there's some off-board potentiometer/switch wiring schematics that I'm unsure about. I've tried to decipher the connectivity looking at some of his other layouts/builds, but I'm not to confident that I read it correctly.
I've drawn a layout and I was hoping that someone in here would have a minute to look it over, and give me some pointers.


In advance thanks
Erik
