Help with Tremulus lune Vero

[Johnnie D.]

Hey Guys,
I tried to build the Tremulus lune on a perfboard and couldn't get it to work. It was really a mess of traces and wires and I gave up on it. I want to try again but have considered the vero layout.

I'm guessing that S1 is the speed LED. Am I wrong? Does it just go to ground?.
I don't even have a guess for the D1 - K.
Since I've wasted this much of your time already, please tell me what NB - is in the red square box lower left.
I saw this board in another thread so I'm guessing it works.
Thanks for putting up with me.
You Guys Rule!!

It looks like S1 is the positive end of the rate LED. Looking at the schematic (http://fuzzcentral.ssguitar.com/tremulus.php) you can see that the negative end of the rate LED connects to the junction of two 1k resistors (R13 & R14 on the layout). This is labeled D1-k on the layout.

NB just means Nota bene, latin for "note well".

Don't worry about asking questions!! We all starts somewhere!

Thank You!
I appreciate you guys so much.
You know how you think something is true but you really need conformation?
