Here’s a storyboard of replacement of the standard piezo transducers with the Ghost version. The Ghost saddles come with long screened single tails with 2-pole 2mm connectors. The standard transducers and saddles are removed by desoldering the single solid-core wires from PCB pads and unscrewing from the support bracket. The PCB was cleaned up & old solder wicked from the solder pads & replaced with new. The new saddles were installed one at a time but as there is no pad for connecting the ground return (screens) of the screened single wires, a length of 16SWG tinned copper wire was soldered to the two grounded connector tabs to provide a connection point. The new wires just fit through the PCB drilled holes, and the wires are stripped to separate the screens from the cores. Screens are twisted, tinned and soldered to the new ground bars and the signal cores stripped, tinned and soldered to the connection pads. Leaving a service loop on top to allow adjustment of the saddle is important as is keeping the unscreened length to a minimum. After all 6 are installed hot glue is used to strain-relieve the thin signal wires. Bridge refitted and guitar re-strung then output amplitude of the signal from each transducer checked on a scope. Output voltage is 3 or 4 times greater than the original transducers but no sign or waveform clipping. Next is to give the guitarist his upgraded axe back and see how it sounds!
