HELP! Marshall Supervibe Resistor

I recently picked up a Marshall Supervibe pedal of EBay sold as faulty. Looking at the main circuit board, resistor R14 had burnt out. The previous owner had removed the resistor so I don't know what it is meant to be!

Can any one help me find out the resistor value (labeled R14 on circuit board). If you have a supervibe its easy to check. Just unscrew the 4 base plate screws and battery compartment and take a peek at the circuit board.

If any one can help I would really appreciate it.

Cheers,

CKS
