You folks using double batteries:
Are you wiring in parallel for 9v and extra capacity, or do they make 18v circuitry?

Oh yeah, no, I'm leaving mine as is. I was just curious as to why some have 2 batteries. I never knew they made 18v electronics for instruments. I assumed it was all 9v.You wanna use whatever voltage it was stock (likely 9v on that bass)
Wire nuts are pretty much frowned upon in instruments... I'm sure you meant solder and heat shrink...Crap, that's gonna need a ton of wire nuts.
I might need to make the cavity bigger.

Is it too soon to say “I told you so”?
I was gonna take a pic with it all loaded up with oversized wire nuts and see how many people had a nervous breakdown by the time I got home from work.Wire nuts are pretty much frowned upon in instruments... I'm sure you meant solder and heat shrink...![]()
Brilliant! I'm totally going to do this at some point, but be sure to get them all neat and tidy of course.I was gonna take a pic with it all loaded up with oversized wire nuts and see how many people had a nervous breakdown by the time I got home from work.
What about different color heat shrink?Correct. Current doesn't care what color the insulation is.
But try telling that to my OCD.
That could work.What about different color heat shrink?

Your pickups have something north of 5,000 feet each of 36ga or finer wire. An extra ten or twenty feet of 28ga around the controls will be nothing.That could work.
I pulled apart a VGA cable and it has most of the colors, but the wires are something like 28 ga.
Not sure I wanna go that thin.
That's funny, before leaving work today, I cut up the vga cable, snipped off a foot of cat6 and rummaged through the electronics recycling box in the storage room and took a few snippings.Rainbow ribbon cables were a thing, but I think they are more of a past thing now, and thin wires. If you are good hoarder you might have some multi-conductor cable that might be different colors inside. Or junque electoniques with wires inside (though most of those are mono-colored in modern stuff) If you are one of those clutter-free people you'd have to scrounge at the recycling center, or on trash day, or from some hoarder you know... but you had a VGA cable
If 24Ga solid will do you, Cat5e/Cat6 network cables (for use in walls/ceilings) have 4 colors and two patterns pre-twisted. You can find 23/22 Ga, but not easily. The stranded stuff in patch cables is usually also smaller wire again.
As for reasons for a battery box, one is so that if the battery goes bad and leaks you don't have corrosive goo all over the electronics. Compartmentalize the damage.![]()
