1 gresco 2 years ago This is weird. Last year I installed a TV Jones harness in my 2002 6122/62 Country Classic. I was hoping to eliminate a slight ground hum with new wiring. The harness went in beautifully and I uploaded some pics of the project on these pages. I didn't notice any significant changes with the new harness, but I do know I now have better pots and switches. The hum was still there despite my paying close attention to the grounds, and the attachment to the tailpiece. I lived with it because it only does it in my house, but it's the only one of 7 electrics that does it. (My house doesn't have 3 wire grounded wiring.) There is a slight hum while playing (less than a single coil hum) but when I put the standby switch to standby (middle position) the hum really shouts. Consequently I never use that switch. This year I decided to upgrade the p/ups to TV Jones, assuming that my '02 p/ups were ceramic, not alnico. I was also hoping that with luck some this might help the ground hum. So I ordered a Classic neck, and a Classic Plus for the bridge. Everything went fine except I was surprised that the bridge p/up was a lot thicker than the original. I had to remove the (mousepad) shim to allow it to fit under the strings at proper height. No problem. I also pulled out the two vol. pots and soldered the p/ups directly to them, as is proper. It's pretty easy with these guitars because of the removable back plate. The p/ups sound great and I'm happy. But I still have the hum, and now my mud switch does absolutely nothing....no change at all between the three positions. The hum while playing can be eliminated by turning the master volume to full on or below 3/4 vol. At 3/4 vol. it's still there. I called TV Jones and spoke with a tech lady. She said she never heard of any of this and would have Tommy call me....he wasn't in the shop at that time. That was two days ago. I'm guessing he didn't get the memo or he hasn't come in yet. I'm stumped, but am still enjoying the great sound with these p/ups. Anyone have any thoughts?
