peter	Re: Morley Vol. Wah If I remember rightly, what you need to do is bypass the 68k resistor with a wire, and disconnect the photocell.... try to trace the circuit for the 'volume' pedal, it should be just those 2 parts (if it matches mine, that is!) Regarding the power supply, if it doesn;t hum you might not want to bother... but if you do want to do it, look for (I think) 3 electrolytic caps that are about 50 uF and 50 volts... they will be the biggest components in the circuit board. Replace them with about twice the value, and twice the voltage rating, being careful to install the new ones with the CORRECT POLARITY! feel free to ask questions! peter
