Thanks for the compliment, Stangjag. It didn't really cost much to do the mod cos I did the wiring myself (with some help from dad 😀). The cost is mainly the hotrails pickup (got it from ebay), a new toggle switch and routing done by a local guitar tech (around US$32).
It was a tight fit for the 3-way toggle switch on the lower horn cos I retained the use of the 2 other sliding switch and I had to sand off part of the toggle switch to be able to fit it into the cavity.
The Jaguar pickups are AV reissues which I've replaced a long time ago.
Oh, for clean tone, Hotrails definitely can't nail it well...but it doesn't bother me cos I can still use my jag pickups for that role. The Hotrails give a slight extra juice when it comes to distortion though 😉
