ROGER MAYER 9090A WAH UPGRADE KIT

The 9090A electronic upgrade has been designed to fit into the CryBaby or Vox housings that Dunlop Manufacturing produce. The electronic upgrade replaces the complete standard electronics with a custom designed circuit card, new potentiometer to give a more progressive and controlled sweep, new jack sockets and the problem of the original guitar tone being made dull in the bypass mode is also eliminated. LED indication of status or true hard wire bypass are available through the use of a DPDT switch instead of the original SPDT version. The multiple wah sweeps are controlled by a rotary switch on the side of the housing a multi-turn pre-set potentiometer on the circuit card controls the boost level.
