Fuzz' life cut short because of something shorted?

[zener]

I built the one-knob Muff Fuzz from http://www.generalguitargadgets.com/v2/diagrams/muffpl.gif few hours ago. I used a DPDT using 2N3904  true bypass w/ led from Joe Davisson’s site. The whole circuit including the bypass switch worked from the first time I wired and boxed everything. After playing with it for several minutes, I decided to put my LPB into the signal chain. I plug my LPB before the Muff Fuzz, took my power supply and plug the LPB into it. The Muff Fuzz was still on battery. As I hit the switch, I heard this hum and realized it as the sound of power shorting. I switched off my PS right away and tested the two pedals. The Muff Fuzz stop working from then. When the switch and led is on, I only hear a signal that sounds like it is bypassed, as if there is nothing in between the guitar and amp. I switch it off and I hear nothing. I took my audio probe and discovered that the signal that went through the circuit sounds still the same, no fuzz. I thought that there might be components there that were damaged from the short. I swap Q1 with that of my LPB and it’s still working. I wasn’t able to swap the Q2 because I didn’t socket it. The Q2 is what I suspect to be the culprit. I desoldered all the wiring and solder them back and still the same. I found nothing else that may cause it not to work. It stopped working only when I plugged that faulty PS.

Another thing. I was also amused and thankful that my LPB is still working. It was the one I plugged into my faulty PS. The Muff was on batt.

What voltages should I have in the collector of Q1 and Q2? I measured around 2 for the Q2 and nothing for Q1.

Do you think I’m right with my suspicion with the Q2? How about any other component that may have been damage?

Thanks for any help.
