Hello, I am new to the forum, but have a question. I have a 1976 Strat. hard tail that I decided to change out all three pots. The middle tone pot scratches very slightly, but instead of changing just the one pot, I changed all three. They have the original grounding rod, and original cap. The wiring is still complete other than I desoldered the ground rod from the pot that just started to make the scratching sound. It is so slight, that I am sure it could be sprayed with electrical cleaner and it should clear right up. Anybody have an idea on what the three pots are worth, dollar wise. I am never going to sell the guitar, so I am not too concerned about keeping it pure original. I did purchase it new when I lived in Las Vegas. Thanks for any input , it would be appreciated.
