Feb 18 at 3:00 comment added Glenn Yes! There is a curtain attached to the pedal that covers/uncovers the LDR's. The bulb's brightness remains constant. At least it appears not to dim when signal is applied through the pedal.
Feb 18 at 2:57 comment added Peter Bennett Seeing the full schematic, it appears that the 387 bulb is relevant. I assume that the bulb shines on the WAH LDR at the top of the schematic. The bulb brightness will depend on the current drawn by the circuit, and will affect the resistance of the WAH LDR.

Feb 18 at 2:07 comment added Peter Bennett A 387 incandescent bulb is rated for 28 volts, 40 mA and would not normally be used with a series resistor. In that circuit there is apparentlu no path for current through the lamp so the lamp and resistor are irrelevant.

Feb 18 at 2:02 comment added vir Where did this schematic come from? Please link the source. Is 387 the resistance of the bulb? A part number? Polarized capacitors are polarized for a reason. Flipping them around will destroy them.
