corrosion

I'm getting this residue from my 1974 Ripper pickguard; I know vintage pickguard material has a tendency to behave strangely, like shrink or emit gases, but I don't know enough to prevent potential damage. Looks like its coming from cracks or imperfections, and it seems to be a liquid of some...

I recently bought a new Pigtronix Ringmaster and I noticed some odd residue on the PCB. Just wondering if the experts could tell me what it is and whether I should be concerned about it. Thanks!

Been out of playing for a while, and want to get back in... Hobby playing only... Had past problems with long scale basses, due to short fingers and sweaty hands (and macho-BS "image issues") so getting Squier Jaguar Short Scale. I used to use D'Addario halfrounds, but they were squeaky, sticky...

There's a bass in the back of my closet that I haven't touched in about 2 years... The scary part: It has 2 9v batteries and I have not changed them during all that time :nailbiting: I'm afraid to open it. What horrors lie within?

I am looking to get a set of strings that is very resistant on gunk/corrosion or a set that works really well with denatured alcohol. My main goal is to have an uncoated string that doesn't "break in" soon for a reasonable price.
