In-line Kill Switch for Guitar

I love using the old Randy Rhoads Les Paul trick, flicking the 3-way switch, with the treble pickup cranked, and the rythym pickup turned all the way down! It produces that cool 'machine gun' type of effect, cutting your guitars output, on and off, rapidly. Carlos Cavazo, Randy's replacement in Quiet Riot also uses this effect on the instrumental 'Battle Axe' on of my 'go to' solos!
You can do this with Les Paul's, of course, and with any guitar, that has two pickups, with a separate volume control for each. Same goes for guitars with mini on-off switches for each pickup. However, there are many guitars, single pickups, or with only a single master volume control etc. that you cannot use this neat little trick/effect. In my experience, more guitars than not, are incapable of this type of switching. My new Kramer Stagemaster acquisition, for example, cannot do this. Rather than modify my guitars, I decided to make my own pedal, to place in-line, with the guitar input cable, to accomplish this. Basically I used a DIY pedal chassis from Pedal Parts Plus

Their products are great quality, feature standard or customized powder-coating, and the prices are extremely reasonable. They had super-fast shipping, as a nice bonus. I bought a small pedal box, similar to a classic MXR effects box in size and shape. I had it powder-coated, in copper vein, as it looked really cool. I also purchased two Switchcraft input jacks. Basically I will have one 1/4" input, one 1/4" output, and a standard 3-way switch, in line to shut off the connection, between the two. The 3-way switch, I had on hand, from the new Charvel San Dimas series guitars. The wiring is simple; the hot wires are connected to two lugs, on the three way, the grounds are connected together, and to the final lug on the 3-way, to ground out the signal.
Here is the completed 'Kill Switch' pedal:
 
I rigged up the switch, near the input, on my amplifier. I used industrial Velcro tape, to mount it. I also used a cheap 1' input cable, that I had, on hand. I will be upgrading to a proper, Monster Cable, as soon as it arrives!

 
It is painfully simple, and it works great! I know it is a bit 'low tech' but sometimes the most simplistic, shade-tree engineered products work the best!
