I knew there would be a time when getting my nephews into music would pay off. 
Last night, I got a text from my bass playing nephew about a cheap bass on Offer Up. So, I messaged the seller this morning, and unlike my last Offer Up dealings, the guy actually wanted to sell the bass! We met up, agreed upon a price, and I brought the thing home. Easy peasy.
So what is it?

Well, the hardshell case says Peavey on it...


It's a 1987-vintage, USA-built Peavey Foundation S. They made two flavors of Foundation basses back then: the regular dual humbucker Foundation, and the P/J equipped Foundation S. I've wanted to pick up a USA Peavey for a long time, and these ones are tough to find. Last one I found for a reasonable price looked like it was dragged behind a truck and was $100. This one was in rough shape, but much better than the one I looked at previously, and it was... get this... $40 with the original hardshell case. The case alone was worth it! You can't go wrong there.
Like I said, it was rough. Some pics:



There were dings and dents all over it, and there was sticky black tar all over the poor thing. These basses came with passive Schaller pickups, but the P pickup had been replaced sometime on it's journey with one from a SGC Nanyo bass from Japan, which is a rare piece and completely random. Those basses have passive pickups with some rudimentary preamp circuitry, so there were some extra wires stuffed in the cavity, as you see here. Also, someone metal foiled the cavity, and used what appeared to be solder to link the pots in some places instead of wire. I feared the worst, and was planning a complete gut job already.
But, I took some stuff apart and started cleaning, just to see if I could get anything out of it.

The bridge was disgusting. These use a weird Peavey-only bridge, so I was going to have to make do with what I had.

Better.

The frets were not in too bad of shape, but they were heavily tarnished. The one on the right was after the first round of polish.
And the result, after a long cleanup session and restring:


Much better. This thing was disgusting, and now it's not as disgusting.

This Eagle One bug remover really saved the day here. I liberally sprayed it all over the bass and let it marinate for about 10 minutes. After that, the tar-like goop that was smeared all over the bass could be wiped off with a paper towel. It does wonders on cars, too. Highly recommended!
And the best part: to my surprise, I plugged it in and it made bass sounds! And not only that... it sounds AMAZING. It has a surprising amount of growl and, for a lack of a better term, balls. I'm going to source a new set of knobs, clean the pots, and put it into service!
