Emg Pickups

I have a question,
do all emg pick ups need a batery? because i dont want to charge it ever 3,000 hrs ( i know it seems like a **** load but im lazy) and when ever there is a battery oit makes the thing ur using seem worse, because when it is about to die or close to it, the tone sounds like ****.

Re: Emg Pickups

all active PUs need battery, there are some pasive EMGs which do not need battery but Dimarzios and Seymour Duncans Sound way better.

Re: Emg Pickups

I'm surprised there isn't another way to power active pups through a special guitar cable (phantom power?) or something. (of course maybe there is and I haven't seen it yet)

Re: Emg Pickups

Can I use multiple batteries?
Yes. If you've got room for multiple batteries in your guitar, you can use two batteries wired in series to power your onboard circuitry at 18 volts. The output level will not appreciably increase, but you'll have increased headroom and crisper transients. This is especially useful for percussive/slap bass styles where you can generate enormous instantaneous power levels across the entire frequency spectrum.

You can also wire two batteries in parallel to provide a regular 9 volt supply but with much longer lifespan between battery changes.

Although most of our products are rated for 27 volts, we recommend a maximum of 18 volts. The additional benefits of 27 vs. 18 volts are negligible.

How long does the battery last?
All EMG pickups and EQ systems are designed for extremely low current drain. In addition, the pickup jack included with all models has a switch that disconnects the battery when the guitar is not plugged in. To maximize battery life, you should always unplug your guitar when it's not in use.

The Specs Page includes current requirements and estimated battery life for each model. Generally, each pickup requires about 80 microamps (uA), except for the Vintage Series pickups which require 220 uA each. EQ circuit requirements vary widely but are higher than pickups.

For your reference, a standard 9 volt alkaline battery provides 580 milliAmpHours (mAh) of power. That means that it will provide 580 milliAmps for 1 hour or 1 milliamp for 580 hours. There are 1000 uA per mA. You can figure the approximate battery life of any setup by adding up the individual power requirements, then dividing 580,000 by this total. Here's an example:

1 - EMG-81 = 80 uA
2 - EMG-SV = 220 uA*2 = 440 uA
1 - EXG = 410 uA
--------
Total required = 930 uA

Total life = 580,000 uAh/
930 uA = 623 hours
If you left your guitar plugged in day and night, the battery should still last a month. Under normal playing conditions, you would probably be looking at changing the battery twice a year. Of course, you should treat these numbers conservatively and not try to drain every last uA out!

u can use stereo guitar cable and send DC 9 volt in right channel and get guitars signal from left one, u'll need little box which will do this job. (to send electicity to guitar and separate signal to another mono out mounted into this box). but in this case u cant use wireless units which work great with active PUs.

Well yeah. Only active pickups need batteries, but the battery thing really isn't a big deal. If you unplug your guitar after you finish practicing (which you should do anyway to keep from yanking it out by accident) then one battery could last you about 6 months. And if your guitar is rear-routed then you can put the battery in the electronics compartment easily. Of course, if your guitar has a pickguard and is front-routed then you'll have to remove the pickgaurd for this but you could simply schedule your battery change around your next string change.

With any pickups, you have to decide what kind of tone you want and choose accordingly. Active EMGs sound drastically different than passive Dimarzios and Seymour Duncan pickups. Some people prefer one over the other while others like to use them both but sometimes for different things.

Re: Emg Pickups

Ive had my EMG 81/85 set in my Ibanez RG520QS for nearly a year now and im using the same battery i bought when i installed the pickups. I measured its voltage the other day and it still had 8.8 volts of power which is plenty. i play anything from 30 mins - 2 hours a day. There has been no change to the sound or loss of power. Man if you can't change a single battery once or twice a year then you are really, really lazy. EMGs are worth the extra effort.

Re: Emg Pickups

LoL yeah i am pritty lazy, but the thing is id need some one professional to change the battery, (im not that good when it comes to repair or fixing up a guitar) so it would be a hassle.

Re: Emg Pickups

death meta, but they also have to pull off good clean tones, but mostly metal.

Re: Emg Pickups

well from Dimarzios i think X2N in Bridge for Hi-gain will do and maybe paf pro fro cleans
from Seymour Duncan Bridge: Invader or Dimebucker and for cleans in neck use '59

someone correct me if i'm wrong

Re: Emg Pickups

want metal with good cleans? emg's... they are the only high output pickup with a good clean tone. Just get them man... the batteries aren't a big deal.
