do you have the multimeter on the 20kohm setting?

all the multimeter is doing at the moment is checking for a complete circuit, it only Displays 'resistance to 1000 ohms'.

I just can't believe it is not a simple short or something, as it just stopped working randomly.

I think it is a short somewhere. something between the rhythm switch --> lead vol --> output jack is shorted or broken. maybe you can take a picture showing the underside of the pots on the lead control plate?

Do you mean that maximum resistance it'll read is 1000 ohm? If so, you're on the wrong scale, because it'll read anything over 1000 (your pickups for instance), as being an open circuit. Set the ohm meter to a higher range setting (say 10k [10,000], or 20k [20,000]). Put the Common (ground) lead from the ohm meter (it'll be the lead plugged into the "Com" jack - use the black colored for the "com" plug, since in electronics, black is used to denote ground for power purposes). Since the volume pot is typically used as a ground, put the black lead on the pot can. To find out what's funky, set the switches to the way they are, when things go weird for you. Then trace the electrical path, starting at the plug point for a cable jack, following towards the switches, and the rhythmn circuit. Where you hit an open circuit ("OL" if you're using a digital meter), or resistance goes to zero, is where things are going bad.

Thanks I'll try all the suggestions this afternoon.
