Well it was for me. James, I would advise you to proceed with caution. After all, your mileage may vary! On the other hand if I can do it, anyone should be able to.
The one thing I would mention is that I have a really good intuitive sense of how to wire things by looking at them. Must be some sort of savant, because I sure don't have any actual knowledge or training! Just a sense of "well, that goes there, so now it needs to go there". I buggered up the circuit board in a couple of spots and had to do some really delicate soldering to pull it all together. That intuition saved my bollocks in those instances as well.
Now if I can just sort out that intermittently noisy short in my other single pickup guitar which has the stutter switch and the push/pull coil-tap. It should get the next permanent wireless...
