I've seen a few of these threads floating around but I think there should be a single thread with information helping those decide if they want to try this mod, since its so easy and the change can be pretty drastic and is just as easily reversible. I would also like to have information on people's findings on the difference in their guitars after they did the mod.

Many of the information I've come across on this tell you to desolder the joint on the input jack - the truth is you don't need a soldering iron, you're just running two 9 volt batteries in a series! Here's a simple way to do it without a soldering iron.

What you really need:

9 Volt battery clip
9 Volt battery
Wire strippers
Electrical tape (or wire nuts)

What to do:

Make sure you have enough room in your cavity for two batteries!



1. Disconnect 9 volt battery
2. Cut the black wire that's circled
3. Strip both ends of the wire you just cut (and the ends of your new 9 volt battery clip if they aren't already)
4. Connect the black wire of your new clip to the black wire that's still attached to your input jack
5. Connect the red wire of your new clip to the black wire of your old clip
6. Insulate with electrical tape
7. Attach two new 9 volt batteries, put the cover back on and enjoy

For those who like pictures:



What I would also like to have is how to put a switch that selects between 9 and 18 volts. This would also be a good indicator in hearing what the differences are.

I'll post up real pics and my findings soon.

Wiring with switch:

This one will require soldering and a little experience:

(switch position in picture indicates 9 volt position)

STICKY! (or add to an existing tut thread?)

great idea, the idea's tossed around so much here on UG, now we have some proper reference.

awesome. and 110% necessary. it should also be noted that this mod could probably be used on blackouts too, not just the EMGs....im not sure bout that though so dont quote me!!

I'm dont know what kind of battery clip the EMGs have, but if they have the more bendy type you can do this

I came across wiring the mod with a switch to select between 9 and 18 volts. It looks good but I haven't tested it yet - I need to get a two way switch. I added the picture to the post.

The sound is pretty distinct at 18 volts. Its hard to explain but it seems to give more clarity and punch from the individual strings, you can hear it when you're hitting chords. It's similar to a dimebucker except awesome.

Thanks guys. I'm pretty sure this power is reserved for mods.

uh if you use the switching option, will one of the batteries die earlier or will they always drain equally?

also, over here http://www.musiciansfriend.com/product/DiMarzio-Two-Position-DPDT-Mini-Switch?sku=424666
this switch loosk like it has 6 of those things intead of three in your 2d picture. can you explain to me how that works?

the extra battery will not drain when its running just on 9V mode

you need SPDT on-on switch, that DPDT you posted there would also work (you just forget about one half of it) but its overpriced as hell

That's a double throw double pole (DTDP), you want a double throw single pole. The middle is always on, the sides are selected depending on what way the switch goes.

Edit: seljer beat me to it. I'll make a note of this in the main, and that the switches position in the picture indicates its using 9 volts.

I did not hear AS much as a difference as everyone says when i did this a few months ago, but there is definitly a difference there. It opens up and expands the tone, makes it less compressed feeling. I say it's a must for anyone playing anything other than weird metal or grunge or something. 18v can show you a little more color and clarity to your signal.

Something I noticed after doing the mod is how much LESS prone to distortion my amp is.

The 18v mod increases the headroom of the pickups and in doing so, the signal is cleaner and less compressed. You'll have much greater articulation when using lots of gain and much better cleans, but IMHO, if you're relying on the pickups to push your preamp, you may want to install the switchable setup shown above (Great BTW ).

can you just pull out one battery if you want to 9v it again? that could take me like a minute.

like mentioned above, you can short the extra battery clip


put a little piece of aluminium foil over the two and fast another battery clip over it (or a load of electric tape)

or take a third battery clip and connect 2 terminals to each other

or rip apart an old 9v battery and take out the connector there and solder the terminals together
#18
So here's a question...

If I have a 2 humbucker guitar with a 3-way switch (Which I do), is there any way to use a 5-way superswitch to select certain pickups @ either 9 or 18V? For example:

1. Bridge Humbucker 9V
2. Bridge Humbucker 18V
3. Bridge & Neck Humbuckers 18V
4. Neck Humbucker 18V
5. Neck Humbucker 9V

sounds no good. just do the 2 way on off switch. that's easier and more efficient. and you get to killswitch id you want to.

what guitar do you have? you might be able to just do it on the pickguard or something. or if you can,, push pull on a tone pot or soemthing

I think what I'm going to do is use a spdt slide switch and cut a hole in the electronics cover for it, and seems like it would be a good solution for anyone else.

It's a pack of two, but oh well

It's small, shouldn't be accidentally be hit, and worst case scenario is we messed up a replaceable piece of plastic.

I've done this mod to my Jackson with a single volume.. like I posted above I might put that slide switch into the back plastic. I just need to figure out the best way to route a hole for it into the plastic. I can't do it for two weeks though until I'm moved back into school. This could be a good solution for you as well.

Need the 25k

The push pull pot is a good idea if you have enough room for that the two batteries. I might opt for this after I take a look and see if I have the room.

Probably the way I'm going to go if the 5-way idea is impossible.

Personally, I don't really like push/pulls because I tend to forget about them. If however the 18V option is a part of pickup selection, there is no way I'm going to forget its available.

The 5-way switch does sound impossible, or at least I can't think of anything off the top of my head due to how the grounding works when switching between 9 and 18 volts.

Ideally you would want a switch for switching 9 to 18 volts, and then another switch for your pickups.

I figure one of those 5-way super switches has 4 completely independent switch paths. 1 set of lugs for pickup switching, another for voltage switching.

Seems like it wouldn't be too complex but I'm not experienced enough with electronics/switches to know whether or not I'm right about it.

EDIT: Here's what I'm thinking...

0 – To volume
1 – Bridge pickup
2 – Bridge pickup
3 – Bridge pickup
4
5

0 – To volume
1
2
3 – Neck pickup
4 – Neck pickup
5 – Neck pickup

0 – From 1st 9V negative
1 – To ground
2 – To 2nd 9V positive
3 – To 2nd 9V positive
4 – To 2nd 9V positive
5 – To ground

Negative from 2nd 9V to ground

1 – Bridge pickup 9V
2 – Bridge pickup 18V
3 – Bridge and neck pickups 18V
4 – Neck pickup 18V
5 – Neck pickup 9V

Yes, no?

It might be possible. It would be a nightmare to actually implement and solder on the superswitch. If you're going to give a go, good luck and let us know how it goes.
#31
Word.

I'm going to talk it over with a friend of mine who does all manner of guitar repair and wiring. I'll see what he says and if he thinks it'll work we'll go for it.

I'll post pics of the cavity when and if it gets done. I am very intrigued by the possibility and that usually means it'll take a week or so for it to get done...

I did the 18volt mod on the EMG's in my Jeff Loomis signature today!

It sounds awesome! Alot more deffinition on each tone, alot of clear buttom and the best high end I've ever heard!

All I did was to connect the two batteries in series (the easiest solution)! I mounted the extra battery in a little black plastic holder I found amongst all my electronic spare parts!
Everything works fine

I highly recommend this mod to everyone who want the most tone out of their EMG's

btw, this thread inspired me to do this mod! To begin with I hadn't got the nerve to start cutting the wires in my Loomis, but after hearing the outcome I'd say it was worth the effort!
