+1 about BKPs pre-wired guards.
I got one with my ITs, my first order. I wanted a new guard anyway so that I could swap pups around easily if I wanted - I looked at what BKP charged for it, priced up the parts separately, and decided that BKP's was good deal.
I wasn't aware at the time how much "personal attention" the standard orders to BKP get, though. I'd assumed that they'd slap "stock" ITs into a "stock" prewired guard - and I would have been quite happy with that for the price. However, I use the middle knob as master tone and leave the bottom one disconnected - I could do it myself easily, but I added something to that effect in the notes on my order, just in case it was possible.
When it arrived, it was all beautifully assembled, exactly as requested, and the "spare" pot hadn't ever been soldered to anything - they hadn't rewired a "stock" pickguard, they'd put the thing together for my order, no extra charge. I was very impressed.
