I have a Fessy with Truetones in it. I LOVE the sound of them, but if you sit within 5 or 6 feet of the amp, they squeal. Last time I played I thought the sound system was squealing, but it was me. My other steels have George L's 10-1. Good pickup also. This is my first guitar with a single coil and I was just wondering if this happens to anyone else.

The best thing you can do is get in touch with Jerry Wallace, and he's the best man on the planet to answer THOSE kind of questions. It may be something simple, hopefully.  |

| normally the frequency of the squeal is the most boosted frequency, if it is high maybe backing off the high setting etc |

That's funny, if anybody sits within 5 feet of my amp, they squeal too....

Do you have the proper distance between the top of the pickup and Strings??
I would suggest 3/16" but no closer than an 1/8".

FWIW, Mine were set to the thickness of two quarters and I had the exact same experience as you did Tyler. I ultimately had to remove it and go back with an XR-16.

Typically feedback is caused by loose windings not potted properly in the pickup. I would suggest getting back to Jerry on this. I had that problem with a few older Tele pickups.
Here is some info on pickup wax potting, etc:
Affects of wax potting. Why is it called “potting?” Why is it used on some pickups and not others?
Wax potting is done for several reasons. It reduces unwanted mechanical vibration within the pickups components like screws, metal spacers, magnets etc. Another important reason is to keep the moisture from penetrating the coil and reduces moisture that could eventually cause the poles to rust on single coil pickups. Single coil pickups after time have a problem with Inner coil pole corrosion (ICPC). Waxing helps keep the insulation protected and if there ever was coil damage, it can be easily repaired. When using varnishes or epoxy potting solutions it usually mean the coils can never be successfully repaired without extreme damage to the coil or bobbin.
The term potting most likely came about because pots were used as in making candles when they were dipped in and out. The pickups are usually wax dipped in an open pot containing hot wax. (Do not try to do this without proper procedures! Extreme Danger!) Gibson style pickups like the P-90, Humbucker and Melody Maker’s originally didn’t have wax potted coils. The pickups had a higher DC resistance and lower resonant frequency than the Fender Telecaster or Stratocaster style pickup. Also the Gibson coil was insulated from the pole pieces by means of a fabricated or molded bobbin. The Fender pickup has the magnet wire wound directly to the rod pole pieces. The amplification used in the 40’s through the early 60’s was not as loud as amplifiers used today and pickups didn’t seem to feedback as much then as compared to today with the use of pre-amps and overdrives.

Thanks for the response. Dan, that's pretty good!  Anyhow, I love the sound of the Truetone, I was just wondering about the squeal. It doesn't happen every time I play, it's just aggravating when it does. I'm not sure on the string distance, as I'm not looking at the guitar right now. I think it might be about 2 quarters, but it's been a while since I checked. Anyhow, I was just more curious than anything, I can stand the occasional squeal but I was just wondering if I was the only one.
Fessenden and True Tones. The best of both worlds!

| Like James said, get in touch with Jerry. I have used his pickups on different steels and have never had this problem. Jerry can help you. |
