Where's my negative voltage? (Mangler)

I've built 4 pedals this week, so I was due for a problem. I will admit, I've done very limited troubleshooting because it's 3 in the moring and at this point I'm too stupid. Upon attempting to bias my mangler (built with NOS trannies from Small Bear) I was greeted with a negative voltage reading of .6. What gives?

-.6v on what, though? The collector of Q2? If so, are you using a trimpot to adjust the bias? Are you sure you have the transistor oriented correctly on the PCB?
