I built up a P19 and the sustain pot is acting funny. It cuts out at both extremes of the sweep. I probed the circuit and got signal all the way through and the voltages are:
Q1&3
C- 4.2v
B- 0.6v
E- 0v
Q2
C- 5.5v
B- 0.65v
E- 0.1v
Q4 (Off the top of my head, didn't write it down)
C- 4.6v
B- 1.3v
E- 0.6v

The solder looks like it had cold joints, but it's not very good solder. Also there was an extra cut I accidentally made on the top leg of the 18k. I corrected it with the leg.
Any thoughts what the problem could be?
