Cepheid Chorus no Sound

[Jarrett]

I just finished putting together this chorus pedal. I've done the Caesar already as well as a Small Clone clone, so I generally know what I'm doing with chorus pedals, but this time I have no sound when I engage the switch.

I have bypass signal, but evidently I have an open circuit somewhere. I also have no led's (edit: leds are working).

I was wondering... I subbed 3 of the 5088 transistors for 2n3904's because I read somewhere about this being okay in certian fuzz circuits. Could this be my problem? The rest of the build looks pretty clean compared to my usual work.

Edit... okay here are a couple pics. I had to chop them up to get them to upload... sorry about that. Also, thanks guys for the super quick responses!

^3207/3007? In case that isn't a typo, you should know that compatible pairings are the 3101(clock)/3007(BBD), and the 3102/3207.

Also, with your own board be mindful that though the pinouts are identical for the MN3007 and the MN3207, the 3007 will require a negative voltage across it's GND to Vdd/Vgg terminals, whereas the 3207 requires a positive voltage across those same terminals.

Also worth noting that applying a positive voltage relative to ground to the 3007, or a negative voltage relative to ground to the 3207, will likely result in a fried BBD.

thanks for your reply
