I've got a Hellraiser running an EMG 81-89 set with coiltap, on a standard 9v battery. I've heard about the 18v mod but I can't be bothered to tamper with it. I have dozens of 12v batteries lying around who knows why, fact is I do.

FOR THE LAZY:
Will 12v batteries work 100% fine with no negative effects on my Hellraiser that is supposed to run 9v? Or should I just not risk it.

What is so difficult about the 18v mod? All you need is to add another 9v battery.

I can get a years supply of free batteries if the 12v works fine

12v wouldn't be a problem but what's the amperage of that battery? That's all you'd have to worry about.

I haven't seen a 12v bat like that, what are they used for?
