Introduction: Easy Killswitch

This killswitch is easy to make and only costs $9.27!
It can be uses on any thing that uses a 1/4 phone jack.

What a kill switch does for those who do not know is when pressed it kills the sound. the button on the top is a momentary on switch that when pushed reroutes the signal to the ground thus shutting off the sound for as long as you hold down the button. By pressing the butting rapidly you can create some cool studdering effects.

I'm going to show you two ways to make the killswitch. One way is just a killswitch and the other has a added rocker switch. If you record guitar or and thing else you can flip the rocker switch over(killing the noise)so there is complete silence well you wait for you part to come up then you can flip it off to bring the sound back. This makes it so when you are waiting there is not the sound of you hitting the strings or any thing else.

If any thing does not make sence to you feel free to PM me with a question.

Credit for the idea to make a kill switch goes to Super Cameraman though I did modify it a bit

Please leave a comment and rate my Instructable I like to know what need to be improved/changed.

Step 1: Materals

Stuff You Need:
Drill with bits
Wire
Soldering iron
solder
2 1/4 audio jacks
a momentary switch(push to turn on)
some sort of box to hold it all

Stuff I Bought:
1/4" Stereo Panel-Mount Audio Jack (2-Pack) $3.99
SPST"soft-touch"momentary pushbutton switch $2.99
3x2x1" Project Enclosure $2.29
rocker switch(optionanal) $2.99
total #1 $9.97
total #2(with rocker) $12.96

Step 2: Drilling

NOTE from here on there will be two sets of steps one for a progect with rocker switch and one with out.

With out rocker switch(pic one)

1 Drill 2 holes (one on either side)for the jacks.

2 Drill one hole in the center of the cover for the momentary
switch

With rocker switch(pic two)

1 Drill 2 holes (one on either side)for the jacks.

2 Drill one hole in the center of the cover for the momentary
switch

3 drill one hole in the front for the rocker switch.

Step 3: Wiring and Sodering

With out the rocker switch.(pic one)

1 Install the switch in its hole, tighten the nut on the momentary switch.

2 Solder a wire connecting the two short posts on the jacks
together

3 solder a wire go from the long jack post to the other long jack post

4 solder wire go from the amp side jack(left)long post to the momentary switch and a wire go from the momentary switch to the shoter post on the amp side jack.

5 insert the two jacks in there holes and tighten the nut on(make sure the long post is not touching the bottem of the box because when you plug in you will bend the jack.)


With Rocker switch(pic two and three)

1 Install the swiches in their holes, tighten the nut on the momentary switch and glue in the rocker switch if you can't get the nut on.

2 Solder a wire connecting the two short posts on the jacks
together

3 solder a wire go from the long jack post to the other long jack post

4 solder wire go from the amp side jack(left)long post to the momentary switch and a wire go from the momentary switch to the shoter post on the amp side jack.

5 solder wire go from the amp side jack(left)long post to the rocker switch and a wire go from the rocker switch to the shoter post on the amp side jack.

6 insert the two jacks in there holes and tighten the nut on(make sure the long post is not touching the bottem of the box because when you plug in you will bend the jack.)

Step 4: Mounting and Playing

To finish the project up lable the sides some how so you know where the guitar plugs in and where the amp plugs in.

You can mount this killswitch any where and you can take it off if you don't need it. I keep mine velcroed to my pedal board but you can mount it to your guitar or keyboard. Jest about any thing that uses a 1/4 phone jack you can use this killswitch.

I hope you have a blast making all kinds of weird noises with this and I would love to hear and see pictures about how it came out. If you liked my instructable please rate it.

I made one last nite,Before I saw this....Its the same W/O the rocker, but I used Command picture hanging strips to mount it on my guitar. That way I can remove the strip and not have to scrub adhesive if my guitar if I ever want to remove it.

good post! will 1/4" Mono Jacks work? Any difference? Also, does it matter if the Mono Jacks are open or closed circuit??

What gauge wire should I use?

Fantastical! My bf's a guitarist, and for his bday my plan is to connect two homemade loopers (outlined in this instructable), each with their own on/offs, to your kill switch to overall make a two channel looper. I'm pretty excited about it (and the fact that it automatically means he's gunna have to step it up for my bday! ;D) and I'll report back if it's successful! Whee! =D

 can i just twist instead of solder?..and any ideas on how 2 add 2 LEDs 2 the box..1 4 rocker and 1 4 button?????

author
biggunner (author)izatrini4eva2011-01-12

u cant add leds because there is no power to power them, unless u ran external power... but you could twist it, but its better to solder....

hey man, does the colour of the wire matter? are their differences in the wires? i'm a dummie, but i'm pretty good @ soldering, so the wires are the only thing i'm worried about! (btw i don't want comments like "you should let someone with knowledge do it for you!")

author

color is personal preference and to keep track of what gets wired where

author
darkria 45 (author)Sybr3nSchaaf2010-11-05

the color of the wire does not matter at all.some wires have lots of small strands, and other have one thick peice, itl be best to use the stranded

author
Glockenator (author)Sybr3nSchaaf2010-09-03

Wire color doesn't matter. It's all the same wire, it's just colored so you can easily keep track of which wire is which

author
Glockenator (author)2010-02-23

is this an actual Gibson/Epiphone SG or is it a copy?

author

looks like a '61 remake..

im getting a (gibson) SG standard for xmas and im buzzing already :DD

Fixed it wired it wrong!

author
joeooo (author)oweng40002010-01-26

 same here! any ideas on what i did? i checked all the soldering it looks solid.. maybe i looked at the schematic wrong..

author
oweng4000 (author)joeooo2010-03-03

What happended to me was i wired one sides Sleeve(ground) to the other sides tip(the place that your guitar signal comes from). once reversed(sleeve to sleeve, tip to tip.)  the buzz goes away.

author
flime1 (author)2010-02-17

PLEASE SOMEONE HELP!!!! i made it and it works but there is a very annoying buzzing sound that happens when i plug it in. Is there a way to fix it

author
Triworm (author)2009-11-18

 does the switch have to be normally open, or normaly closed? please answer.

author
izatrini4eva (author)Triworm2010-02-02

 button is open

Can you PM me a better diagram, I bought the same jacks as you but I have no idea on how to do this.

author

if i did the switch wrong, would it potentially damge my guitar or amp?

author
rubin69 (author)2009-12-05

 ok so ive tried building it and im not sure how to wire it coz i bought an 1/4 audio jack and it has 3 loop things and one long thing so pls can you help

what is the "rocker" switch called in real life, so we're all clear :S?

author
Bradlez92 (author)Bradlez922009-03-11

nevermind :P although, do you think a lighted momentary and rocker switch would work aswell? or would you need some sort of power source?

author
Glockenator (author)Bradlez922009-11-18

i think you would need something has a power supply,but there would be power from the amp so you never know

author
Bradlez92 (author)Glockenator2009-11-18

I'm not as sure though... I mean, there HAS to be some sort of power source. Otherwise we wouldn't have to power other guitar pedals externally, no?

I'd  test it out myself, but I have neither the time or equipment, nor the wild abandon to throw around money to test on electrical trial and error junk in a "what-the-hell-am-i-doing" haze =D.

Glockenator (author)Bradlez922009-11-16

its just rocker switch.no fancy name

author
Glockenator (author)2009-11-18

heres the thing.how does this work when the souns not being passed through the wires in it?

author
Glockenator (author)2009-11-16

do you need a normally closed switch or a normaly open switch?

author
guitardude12317 (author)2009-07-22

is there any way you can make it (the killswitch) into a pedal?? i saw it plugged in on your pedalboard and i was just wondering...

author
toogers (author)guitardude123172009-09-16

just get a bigger button, and use as pedal.

author
mchs60chip (author)2009-08-24

interesting i'll have to try this btw i have that exact same distortion pedal for my guitar

author
CyberCrash (author)2009-06-17

If u got a 2 vol. knobs guitar,wouldn't it be easyer to u to just leave a know at the minimum and turn the key?

author
blink182folife (author)2009-05-12

i'm looking at your schematic and i'm a little confused. if the buttons or in parallel, how are they supposed to kill the sound? i tried it out anyway and sound comes out but neither of the buttons kill the sound. even when i tried wiring them in series it didn't work. any suggestions?

author

never mind, it works perfectly! great guide!

author
tommorellorocks (author)2009-05-12

can this be used to play the solo from "your time has come?"

CLEAN THE DUST OFF AND IT WILL LOOK CLEAN

author
Metal4God (author)2009-04-08

OK! two things, 1.Why add a killswitch? when you persoanlly have a gibson SG, that has a voulme knob for EACH pickup, all you gotta do it turn one pickup off, then use the selector switch 2. why did you stick your pickholder where everyone can see it. plus, it looks like u lose alot of room with it I have a jackson dinky, and that same pick holder, i put my pickholder at the top horn, so only i can see it, and grab it when i need it.

author
Fresh Fruit Boy (author)2009-04-06

Do you have to solder the wires? Does twisting work?

author

Sorry, another question. Where do you get the little cable that you used to connect the guitar to the box?

author
The Landon (author)2009-04-04

where did you get the proyect box?

author
Bradlez92 (author)2009-03-11

youd ont have to place the killswitch in any specific order, do you? like if i have a pedal, the killswitch could go either closer to the guitar or amp, right?

author
azbo1 (author)Bradlez922009-03-19

no it don't matter it'll only affect weather the instrument is "killed" before or after the pedal effects being applied.

littleangus77 (author)2008-05-24

nice man ive been wanting to make one of these and now i finaly picked up a soldering iron so i can. Great insructable, and nice i have an sg too.

author
Bradlez92 (author)littleangus772009-03-11

same here. what series is it? i got a white and gold one with the bigsby tailpiece

hiya, i like the guide, i went out one day and tried to attempt it myself, however when i plugged mine in, no or little noise came from the imput end, however both the momentary/ toggle switches are working well. What have i done wrong with connecting the two jacks so that sound would transfer properly? thank you.

author
Puff (author)2008-12-28

where would one go to pick up the materials I.e. the jacks and the project box. btw i just got that same sg for christmas this year and its pretty nice. I started in march on a squier strat and man do those things suck lol.
