Sign in to disble this ad
.. if the bass is standing right next to it (by its side, not in front of it)?
I have a mesa boogie 412 powerhouse cabinet if that helps...

Sitting it next to anything does not.

"...magnetism decreases as the cube of the distance. This means that the influence of most magnets is only a few inches."

(Can magnetism drain batteries?)
"If the magnet is an electromagnet powered by the battery, yes.
If you use a conducting magnet to short-circuit the terminals of a battery, yes.
If the magnet is strong enough to physically deform the battery, yes.
Otherwise, it's likely to have no effect."

out and ten put them on again.

I find it easiest if I change all my batteries every time the clocks go forward or back. i've never had one go dead in the middle of a gig. There's always a pack of fresh batteries in my cable tote.

And never leave a 412 in your car overnight. Car batteries even cost more. Just kidding......  The magnets wil not drain energy from your active bass battery. Now recording tape........
