clyde wah doa

[ampedup]

i've rebuilt my jh1 into a clyde mccoy, the one with the optional output buffer  http://fuzzcentral.ssguitar.com/mccoy.php   it's volume is real low and it doesn't wah, just goes silent when the pedal is depressed. i'm using a 12v wall wort, no battery connection is wired in now. i accidentally plugged it into a pos center wort, did i ruin something? 
Q1
e-.106v
b-.71v
c-5.2v

Q2
e-4.07v
b-4.5v
c11.02v

JFET
d-11.43v
s-1v
g-0v

i used the standard bc109 transistors and 2n5457 jfet.  thanks

12 volts? should that not work?

[ampedup]

opps, i meant 9v.  i guess reading those voltages close to 12v got the 12v thing on my mind.
hey, i just went and measured three of my 9v warts and got 12v, 16v and 10.5v! is it normal to see that much difference?

[ampedup]

so i had the input going to the collector of Q1 instead of the base, i fixed that and now the volume is there but still no wah, i replaced the 4.7uf just incase i had fried it, but no change.

12v will work fine

ampedup, check if i miss a wire, if your soldering is makin shorts between the tracks or if you are using good transistors. check everything in order (from input to output)

maybe you've read this, but if not, then enjoy it

i was about to sya "check the 4.7uF pol. capacitor, but it seems you've replaced it. maybe it's in the wrong direction.

[ampedup]

thanks, the 4.7 cap is non polarized. i've read that geofex article, that's where i got the idea to change that cap. can anyone comment on my voltages, do they look cosher?

Check to make sure the inductor is actually in the circuit. From your description, it sounds like it's not doing anything. The purpose of the inductor in a wah pedal is to make it a resonant circuit...

[ampedup]

doh! i had the halo inductor hooked up wrong, the geofex article mentioned that could cause non wah, so it works now. now to get the true bypass going. i got a momentary dpdt switch thinking i could just leave the pedal pushed forward for bypassed and then just move the heel down to turn it on. the problem is the switch has enough spring pressure to move the pedal up so it won't stay switched off, damn.

Ta da! Cool, glad you got it working. And, yeah, you need to get rid of the momentary switch.
