Hi, hope it's not a no-no to post about non madbean pedals. I built this pedal:

fabbed my own board:

I'm getting a signal and the filter section of the pedal is working. I used LED's and LDR's instead of the vactrol sited in the parts but in their description they say they did this originally as well.
The problem is I can't get the LFO section to work right. +ve input of U1a is around 4V and my scope confirms that U1a is oscillating and that the signal is making it to the +ve input of U1b, but the output of U1b is a flat 6V and the LEDs just glow at a constant brightness.
Anyone have any thoughts on this?
Thanks!
Wondered whether the type of LED I was using might be an issue but I breadboarded the circuit and it works fine. So I guess it's probably an issue with my board or my soldering or both :P
Oh...hehe...yarp. Little things. I need stronger glasses.
