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
http://www.pedalpartsplus.com/

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!   

 
 

Replacement foam / tubing for Guitar Stands

I recently bought a guitar/display stand, from my local music store. I am hanging a special guitar, and I want it to be prominently displayed. They came up with this cool hanger, that mates up to slat-board, which I already have. They weren't using the hanger, anymore, and sold it to me for $40. I am guessing that it would cost at least $75 retail, for a new one. The stand is made by Ingles, who I have never heard of? It is very well built, and uses wing-nuts and a drum key for tightening! The only problem is that the metal hangers are covered with old surgical tubing. We have all seen the stuff I am talking about, amber in color, and this stuff is old, weathered and cracked. It is literally falling off of the stand. Here is what it looked like:

 So I searched all over the web, and eBay etc. looking for a suitable replacement. Well, I had a hard time finding any information, whatsoever, on replacement tubing or foam, whatever. I wanted to upgrade the surgical tubing to some good quality, dense foam, to protect and hold the guitar in place. Through my search, I was able to find a link to this:
http://www.mcmaster.com/#standard-rubber-hollow-tubing/=o9kdak
Its the product, at the bottom of the page, this one;

Weather-Resistant EPDM Foam
3/4"1/4"±0.039"1/4"4339T6$12.19/6 ft. piece

I ended up buying 3 different products, not knowing which would work, best. The foam, above, was the winner. Let my research and extra cost $$, help you out! The diameter of the metal rod, that makes up most guitar stands is 3/8", I figured that 1/4" ID foam would stretch, for a nice, snug fit. I was right. I did have to use a bit of silicone spray, to slip the foam over the stands metal rod. Here is what I ended up with:



Sorry, the topic for the guitar that will go on this stand, will have to wait! Hope this helps a few guys out!
