Unhappy Active Preamp Question... GV content...

So I went to change the batteries in my Peavey GV and one of the batteries had corroded the contacts on the 9v plug and it broke. Since I don't have a replacement handy, I snipped it, stripped the ends of the black and red leads and twisted them together using only 1 battery. Plugged in it sounds fine. Is this ok? Will this be detrimental in the long run? What are the true effects of reducing the battery power?

Just a little lower output volume. No big deal.

That's what I thought. I'm going to keep it this way. Fewer batteries to buy...

Radio Shack and other electronics suppliers sell the sweet hard-plastic 9V pigtails for less than a buck...

i went the opposite route on my schecter. it has EMGs with an active pre-amp that runs 9v stock. i modded the harness to accept 2 9v batteries so it now runs at 18v. the difference in the sound was substantial.
if you like the way it sounds at 9v then you're fine with the way it is now. there's a lot to be said for less batteries...

I actually run 9-volts in parallel... still 9V but at nearly twice the longevity.

Not even that. Output volume will be the same at 9V. However, you will have less headroom, so it will be easier to overdrive the onboard preamp than it was at 18V. It's entirely likely that this won't ever be a problem.

Will it drain the battery faster due to a higher draw/thirst for juice?

I wouldn't think so but without actually knowing the circuit I can't be 100% sure. Most preamp circuits don't draw very much current at all (almost all audio stuff is entirely voltage driven until the power amp stage) so I don't think you'd see a significant difference anyway.
