Hey guys.  I'm having something funny happen to my LPB build from GGG.   
http://www.generalguitargadgets.com/index.php?option=com_content&task=view&id=72&Itemid=26

I bought a RTS board from them and assembled everything this evening.  The substitutions I've made to the values are R1(430k) to 470k, R2(43k) to 47k, and R6(1.5M) to 1.47 (1M + 470k in series).  The Tranny used is a 2n5089 (from aron's shop) that's socketed and oriented correctly. 

Here's what's happening:  There's no signal going through the pedal on or off.  However, when I depress the 3PDT switch a little bit, the pedal works fine.  I've tried using a 9v battery and a power supply and the same thing happens with both. 

Any ideas?

thanks

seriously though...you may have a faulty switch... you may have "burned" the switch ...you may have a "solder bridge" on the switch.... grab a magnifying glass and your multimeter !

My bad.  I totally only read the first half of it :P

Q1
C= 4.6
B= .71
E= 137.6

I'm not gonna lie, the debug original post is pretty confusing to read through.  Is there anything else that you guys would like to know?

I think I'm going to try another footswitch...
