A $50 Craigs List buy that needed some love. Replaced the bridge with
a vintage style with a steel trem block and vintage saddles. $22 on Ebay.
The stock electronics in cheap guitars like this one are awful.
By far the best inexpensive upgrade you can do to improve tone.
7 way switch and Bournes pots
Installing new Bournes 250k volume pot and tone pots. Installed
better quality .047 caps. Close to the selector switch is a mini toggle that enables 2 additional pickup combos, all on and bridge and neck on only.
There are many differnt wiring schematics to choose from, In this case I opted for a retro wiring
seen on older Fender strats from the 60's. I found a set of vintage alnico 5 pickups on Ebay new for $56.
They really improve the tone of this cheap guitar.
