I have a partscaster with a Dennis Cornell 25db midboost installed. The unit was bought as a whole and fits the holes in a standard strat type pickguard installation, giving Master Vol - Boost - Master Tone controls.
This needs a 9v battery to operate and I have chiseled an appropriately sized cavity in the area just below the middle pickup and in front of the 5 way switch. I have ordered some copper foil with the intention of screening the entire guitar,ie underside of scratchplate, pickup and control cavities in the manner written about so often in these forums. I had been going over my checklist as I intend to do it this weekend when I thought about the battery cavity.
My question is do I just line the battery cavity the same as the pickup and control cavities or are there any other considerations to be taken into account. I am thinking here about any possible contact either the wires,battery or battery contacts could make with the shielding. has anyone here any advice to offer in this regard?. again thanks in advance for any advice offered.
If you're using one of those plastic 9V battery clips to secure the battery that would help bring the battery and its connections away from the shielding a bit. You can also line the area with electrical tape over the shielding to prevent inadvertent contact.
IMHO, the battery is a low impedance DC power source and unlikely to pickup much noise. The DC power rails within the preamp are bypassed with bulk capacitance (all good active analog circuitry is) and are also low impedance.
I probably wouldn't shield the battery cavity anyway.
I not only wouldn't shield that cavity, I'd seriously consider not putting the battery under the pickguard. How many times are you gonna remove the strings, then the screws, to replace the battery? How 'bout just to check it, to make sure it's not the problem when something goes wrong?
Which is why "they" make battery compartments, like this:
Such devices come in all sizes and shapes. This one is from Guitar Nucleus, and they have several more models here. Many other suppliers have 'em, I just took the first thing Google offered me.
Sorry to be a PITA, but that's why I'm here, to think about the negative things, preferably before they happen.
Rule #1: All Lives Are Final. Make sure that the life you have just been issued is appropriate for your needs, before departing the womb.
Rule #2: In case you don't like the life you have, see Rule #1.
If the guitar has a vibrato (often mislabeled as a tremo'Leo) and one can live with four springs or two strong ones, one can put the battery between springs in the vibrato cavity accessible from the back.
If'n it's a parts caster, just cut the pick guard with a hole to fit the battery box that sum gai's like, and mount it from the front.
If anything, folks will ask "what's that big switch for, dude?"
And then, the lies begin...............................
