Ken, just a little question about that little wolf tone device on your A string.
I put one on my A string (same place as yours) and it got rid of my Ab wolf tones - then I discovered that G, up on the A string, had a wolf tone. I tried the little chap on the D string, but it still effected the G.
I've taken it off because it is easier to live with a funny Ab. Have you had much experience with wolf tones? Is there any logic behind how the little device works?
