Hello. This is my latest build. It started off as a gimmick project, but as I got into it, I started taking it more seriously. I doubt it is to anyone's taste, but it's actually comfortable to play and sounds just as you'd expect a solid body reso with a pickup to sound. The only problem is a noticeable wolf tone on the 6th string. It's most noticeable at 12th fret - it seems to be resonating a half tone lower than the actual note. I can hear it also on a few frets lower down to about 8th fret. What are common causes of wolf tones? I suspect it's the solid pine body, but could it be the cone? (it's from the icarus - I upgraded the cone). Cheers, TT  |

A fun guitar ( I have also used Eko necks on odd bodies, )
Wolf tones are usually associated with fully acoustic instruments ( mainly the violin family) could it be the string?
Or is the action too low? Or could the sound be coming from behind the bridge . If your saddle has a deep notch you could move the string out of the notch to lift the action a little,does it still give the same problem?
Does it come through the amp or is it just acoustic?
Could you record it?

A wolf note is usually caused because of a dissonance that occurs when the note is the same as or close to the resonant frequency of the body. It is often to do with design problems. I have often heard it on badly designed & built resonator guitars. While Pete's suggestions are well worth exploring, it might well be coming from the body shape resonance and what frequencies that is reacting with.
That might be total bollox, but I have a feeling it might not be.

Yes, what Michael says.
The thing is that the body is a slab of wood and shouldn’t have this problem. I suspect this is not a true WolfTone, and might be caused by something other than a resonant vibration. Very hard to tell at a distance.

Pete I assumed the body is hollow because of the tea strainer soundhole cover. If it is hollow, the shape would cause all kinds of weird non-musical and possibly wonderful wolf tones. If it is solid, then as you say, it is not a real wolf tone, just something sending unwanted vibrations around. Shine On Michael |

Thanks for the advice.
It is a solid body - the strainer is purely decorative. The action is quite low, and I will adjust the neck angle and increase the saddle height. I had a bronze string on it initially as it was all I had spare at the time, but I think it sounded fine. I put a nickel on for the pick up and noticed it then. There's a bunch of holes drilled in the back, so the cone should vibrate freely, but maybe it's jammed on the well wall. Hopefully it's not a true wolf tone, and tinkering can fix it.
Chere's, TT
