Refresh/Update GSR200 bass wiring

 i got this bass ages ago in a trade for some mac recording gear i won in a raffle but couldnt use.

id never really opened the pot cavity, but when i did, i ignored it because it was such a mess. there were burns on the wires, & the wires were a birdnest. 

i had to do alot of research to make sure the wiring was actually correct, then i could move forward.

i found that my jack was reversed, ie: on common jacks or american/european jacks, its standard to make the longest lug the chassis ground, but apparently on this one, the longest lug contacts the ring on a cable, which i only realized because i was testing with a stereo cable. since its only played through a mono cable, it couldve gone unnoticed otherwise. the signal was sort of quiet, & my battery was always low (around 7.1v), & that would explain it. 

the shielding paint in the pot cavity was also terrible, with sporadic continuity at best. i hadnt set out to, but i decided to go ahead with a copper tape upgrade.. then while at it i decided to do the pickup cavities (grounded to the pot cavity) & adding a bus ground to the battery compartment wall to contact the factory foiled plastic lid (grounded to the pot cavity).

i replaced the jacketed signal wire with nice new tinned copper jacket wire, taco folded in bobbin tape. i trimmed a ton of excess from the single lead wires. i also removed the case grounds & added ground lug ring terminals to the volumes & tone pots to solder the grounds to.

i decided to ground the bridge bus wire to the pot cavity wall with just a piece of copper tape over the splayed wire end, & also added a piece of copper tape over the wire end sitting under the bridge to expand the contact area, which was a total success.

im really satisfied with the immediate & complete continuity at every ground point in every combination with themselves.

i ended up only switching the long & middle jack lug wires (battery neg to longest lug [ring] & phat eq ground to middle lug [chassis]). 

what a fucking improvement.
