you can't go wrong with duracell or energizer. the only thing that's really not recommended is rechargeable batteries because you usually have to discharge the battery completely to get the full use of it. That really wouldn't work with a guitar.

Ah, so just standard duracell batteries you find in the store?

Rechargeable cells only have a nominal output of 1.2 volts, versus 1.5 for alkaline batteries. A nine volt battery has six cells. A rechargeable NiMH or NiCD "nine volt" battery will only have a nominal output of 7.2 volts (1.2 times 6 cells), unless of course the battery has more than 6 cells, in which case the capacity will be compromised in order to fit all the cells. If you only have 7.2 volts to the preamp in active pickups, the headroom will be lowered, and the signal will be more compressed.

...............................oh?

haha he says yes regular off the shelf batteries ;)

metalhobo is correct, stick with alkaline. Additionally, give the 18V mod a shot ... I saw a substantial improvement.

I use energizer

duracell does the same

and about a 18V modif, is it expensive to make such a modif?

duracell works best nobs!

So i just connect 2 nine volts together?

Two nine volts in series.
