It's really not too bad of an installation.
The biggest issue will be getting the circuit board to fit inside the body.
The EC signature body has a special route for the circuit board, I made my own with a router.
I have heard of others getting it to fit in the existing route of a standard strat.
Perhaps it is possible, but it will be tight with the 9v battery.
You also have to get a TBX tone control in there.
Also, it will boost the output of the guitar considerably.
I'm using it in conjunction with a set of DiMarzio Virtual Vintage (Heavy Blues, Blues and Solo) pickups, and frankly, I think it's too much output.
It would be a better match with a low output single coil, like the Lace Gold's that it was designed for.
Just my experience,
James
