Zero Point Micro 2 HELP!!!

Hi All,
I've recently completed the zero point micro 2 board, hooked it up to my basic test rig (rock before box) and the effect doesnt work!
Sound is making its way through the pedal, but all the pedal seems to produce is a rythmic noise: the volume of the noise increases with the mix pot, but no other pots appear to do anything.
the only part substitution: i used a 78L05 in place of the LM78L05 listed in the BOM of the pedal (see link)http://www.banzaimusic.com/78L05.html

I've checked for solder bridges and cold joints: everything seems to be OK. I socketed the ICs and regulator, so I dont think there is an issue with them

Does anyone have any suggestions

Thanks

Yes, verify that you have 5v on pin1 of the PT2399 and 0v on pin3. Then verify that you have about 9v on pin8 of IC1 and 0v on pin4.
