Black Cat Vibe

[crowsmith8]

Does anyone have any experience with this circuit?  I think that it is somewhat based on the original Uni-vibe pedal.  It has the internal LED or bulb in order to produce the phase shifting (I believe it is called the Light Dependent Resistor (LDR) approach).  I hope I have that right.  Anyway, a friend of mine has one and it's not working anymore.  It turns on and the volume knob works, but there is not effect at all.  When I opened it up the LED or bulb for the LDR looks like it is burnt out (looks like a normal burnt out light bulb).  I was wondering if this an easy to find component?  If so, what is the correct name for it, and where can I find one?  The pedal also looks like an 8 year old put it together (lots of bad solder joints and whatnot), so I'm going to try and clean it up first to see if maybe this is the problem, but I wanted to know how to find the new LED or bulb in case I needed it.  Any help would greatly be appreciated.  Thanks.
