EMG 81 pickup battery wiring help?

Just change the battery before you go onstage if you're that worried about it.

9 volt batteries last a LONG time in active pickup equipped guitars. There is no way a freshly installed battery is going to die less than an hour after you put it in.

Seriously, just change batteries before a show and you won't have to worry about messing with your guitar's wiring and maybe screwing something up. By screwing around with the factory wiring, you are actually increasing the chance of a battery problem by creating more places for something to go wrong.

on the grounds which you have 2 9 volt batteries in series, i could think of you are able to basically faucet off the middle to get 9 volts. One obtainable subject is that except there are diodes on the provision inputs of the pickups, there could be a course for leakage cutting-edge whilst the pickups are "off" by using fact the EMGs draw little cutting-edge, a resistor divider could be a danger, even though it could enhance the provision impedance dramatically which i think of i could choose to evade on an audio utility. in case you have room, you are able to evaluate basically utilising a seperate battery for the 9v pickup, although that would complicate means switching. yet another decision could be to run each component on 9v, EMG does say at 18v "you will have bigger headroom and crisper transients" yet how lots, are you able to truly hear it? they additionally say "that's incredibly functional for percussive/slap bass varieties" is that the way you play? if no longer, you will possibly no longer choose 18v

I've never heard of someone doing that. Also, I never have had a battery die on me (still using the same one in my Jackson since I got the pickup a year ago) :P

If it is possible, someone on Sevenstring.org might be able to help.
