"I researched dead spots and read that the string frequency and the fretboard frequency in particular spots can cancel each other out. My instructor said the fretboard was dry and needed lemon oil." All guitars, solid body or acoustic, can vibrate as a whole, and have resonances that resemble those of xylophone bars at a number of frequencies. Since the neck does flex a fair amount at these pitches these are often called 'neck modes', and I'm assuming that's what you're talking about. On most steel string acoustics the lowest 'neck' mode is quite a bit lower in pitch than the low E fundamental. It has stationary 'nodes' somewhere around the nut or first fret, and on a line across the lower bout near the bridge. It's 'way too low in pitch for the string to drive directly on steel strings; on classicals it can be high enough to matter, but the driving mechanism is not direct from the string, but rather through the air and top. It doesn't get moving unless the 'main air' pitch is a pretty close match with the 'neck', and when it does it can actually help the low-end sound. It's possible to find a couple of higher pitched such modes on most guitars if you work at it, but in general they're not anything to worry about. For one thing they tend to happen at fairly different pitches on different guitars. Remember, these are whole-body resonances, so things like the stiffness of the sides and the mass of the tail block can come into play. Too many variables... They're also much weaker than the lowest 'neck' mode, so you would not expect them to have any major effect. Not saying it's not possible, mind you... On a solid body electric the neck is by far the lightest and most flexible part. It's not too hard to find three pretty active resonances of the whole machine it the range of the fundamentals of the strings. Often enough, in the few times I've looked at this, the bridge is on or near a stationary 'node' line for all of the lower modes, so the strings can't drive them by pushing on the bridge.* If there was a moving 'antinode' of the resonance at a fret that sounded that pitch the string could drive it. You'd notice a drop off in either volume or sustain, and possibly a change in pitch of that note, or even a 'buzz' caused by the two polarizations of the string vibration having different pitches, as happened to my customer. It's just (barely) possible that oiling the fingerboard might alter the pitch of the resonance enough to 'fix' the problem, at least for a while, by adding some mass and damping and possibly reducing the stiffness a bit. I don't have data on this, so take that with a very large helping of salt! * Any 'free' vibrating beam, like a xylophone bar or solid body guitar, has a moving 'antinode' at both ends. A string attached to the end can easily drive that. Solid body basses tend to have their bridges close to the bottom end, and I suspect that's one reason they have so much trouble with dead notes. |

In my experience you can actually see these wolf notes if you watch the string vibrate after you pluck it. The fret above and fret below will usually vibrate more freely and for a longer period of time. The wolf note, in contrast, will vibrate a lot and then die off very quickly. You have to look pretty closely, but once you see it it’s obvious. Some of my guitars do it worse than others, and some don’t do it much at all. But I usually can confirm what I’m hearing by looking up close.

The reason I'm doing the Wolf Note Hunt and publishing my findings is that it takes about two minutes to check a guitar and post the results to my list. I might as well do it so I'll know what I have as I pull each guitar out for a playing session and it only needs to be done once per guitar. Even though it seems silly to some, maybe some players may find it interesting.

My D-28A doesn't have any of it anywhere I can find, and that's one of the things that keeps it in my hands. My Clapton has a couple minor ones higher up the fretboard on E and F. Mild. Seems very common to me. Quote:

I think there might be something to this. On my new used HD-28E I was getting body buzz on the E note in three places: Low E12, A7, an D2. (Also a bit less on the F notes one fret up — all three strings.) Besides the buzz, there was a mild thud to the notes — less clarity and sustain.
The tech at Gryphon looked inside and found that one of the wires on the Fishman Aura VT Enhance was touching a side, and he could make it rattle a little. He bent it out of the way and the buzz is now gone. What does this suggest? To me it suggests that there is a resonance frequency at 80 - 85 Hz where the guitar’s vibration is distorted in some way. The amplitude of the resonance interferes with the pure note; maybe it’s out of phase or disorganized or something. If there’s any merit to this theory, then those will be wolf notes (at current temperature, age, and humidity). I’ve built in an awareness of those frets, so that now I make an effort to play them in the cleanest way possible with my nails and distance from the bridge. The upshot is that I can manage having three fret locations that hang back on me. But the best news is that the buzz is gone.

Did you have any success with brass bridge pins to move the resonance to between scale notes?

It's only a 'wolf' if it's a problem, and since sound is so subjective, that means a problem for you. Different people have varying tolerances for this stuff.

Thanks, Alan, I agree, it could be a problem for some players if they hear a note that doesn't sound right amongst others on the guitar. I do hear some notes sounding a bit louder than others as I go along the fretboard, and usually, I hear a bit less volume and sustain as I go up toward the 12th fret on my test guitars but nothing so far as sounding annoyingly diminished in volume or tone on the guitars I've highlighted so far. I need a strong alternating bass for my style and that's one reason I'm checking all my guitars. I think if I heard the OP's guitar I too would find the wolf note he's hearing also annoying.

Norman Blake once said something to the effect of "never trust a guitar without a belly". I wonder if he would say something similar about wolf tones on dreads.

When life gives you a guitar with wolf notes, play Bark At The Moon.
