This is a mod to adapt a under saddle acoustic guitar piezo to a stratocaster block tremolo anda a common piezo inside the guitar body.
Use a rotary tool and a file to make a groove at the upside of the block:
... until the piezo fit it, with only a small part outside:
Screw the other parts of the tremolo with the piezo wire out of the block:
*Maybe you will have to file the wood of the guitar under the bridge, a litle bit, to adapt the extra wire.
Othewise, if you don't use the tremolo arm, like me, it is possible to use the other side of the block, making a extra hole to pass the wire:
Set up the tremolo at the guitar, use the grounding hole to pass the piezo wire and conect it to the guitar circuit. Some hot glue will fix better some parts:
Next step....fix a common piezo at the inside of the guitar body, near as possible of the bridge, using a double face tape:
The tromolo piezo will have a lot of influence of the coils, producing a lot of reverbation. My sugestion is to mix the two piezos with a resistor (or a pot) like that:
* 1M or less... depends on the piezo output level.
Finaly, mixing the pickup mod (http://guitar4geek.blogspot.com.br/2016/06/stratocaster-wire-mod-series-pickups.html) with this piezo mod:
*All pots are 500K
* Other suggestions:
