Location: Yucaipa, California | Ok, I know that by the title of this thread, I'm setting it up for an immediate dive, but....
I have a friend who has one of these little mother's helpers http://www.musiciansfriend.com/product/Groove-Tubes-Fat-Finger-Guit... on each of his guitars, including his LP and claims a noticable increase in sustain/tonal clarity on all of them.
What's the opinion from the OFC? Anyone ever used one? |

Unless the kinetic energy of the strings directly acts on something, like the nut or saddle for example (I'll even go as far as the tuning machines, but that's it), anything thing else that adds mass is just going to be a "sink" to that energy and further dampen it. As for heavy heads tocks having more sustain, I think having solid wood from the neck to the body (even with a laminate neck) IE no neck-joint has a grater affect than more wood out at the end. Unless the extra "mass" had the ability to vibrate sympathetically (capture some of that energy and prolong it's resonance at the loss of some overall volume) like a reverb tank, It's Bullocks. |

Location: South of most, North of few | Tim, I'm just a simple drummer that happens to enjoy guitar, but I know that if I strum a chord on the UTE, I can walk away, grab a drink, come back, and it's still ringing. The UTE is by far the lightest guitar I own, and it is a slot head which would seem to me has less mass than a standard head. Being the bridge is located lower on the bout (12 fret) and it has a carbon fiber top has something to do with it I'm sure.
Fred lost me when he started with the kinetic energy thing, but I do understand his theory of the extra mass acting as a "sink" to absorb energy rather than sustain it. But bottom line is:Idono. |

Location: big island | probably works best on a banjo. of course, tim is known to add mass to his head from time to time too. perhaps clarity and sustain is what that jiffy pop hat does for him? |

If your friend believes in it, you won't be able to convince him otherwise. |

(not bad for a dumb ole wrench,huh?) :rolleyes: |

But, it seems to me that if it is true, the supporting point for the headstock end would be the nut, not the tuners. Same for the bridge end...it would be the saddles, not the actual bridge mechanism itself.
But, what do I know? Not much, that's for sure. Ask the FBO guy, he probably knows! :) |

Location: South of most, North of few | As far as I can reason with my limited abilities, I believe the sustain has more to do with the volume of the body, vibration characteristics of the top and the connection of the neck with the body, than the mass of the head stock. I would think after the nut, it would be a moot point as that is the fulcrum and end of the string's vibration. I really can't believe clamping a metal part on the headstock will improve sustain. But, it might look nice. |

Location: Delaware | I'm getting into this one a little late so pardon any rehashing. I'm only a beginner in terms of guitar playing but I've played trumpet since 1965. This is an interesting topic. We have several factors to consider. Rather than try to touch on all the parameters producing sound and sustain that I am aware of I'll focus on one aspect - effects of mass on vibrating air columns.
Sometimes the difference is imperceptable to the human ear, so the product mentioned to start this topic may or may not make enough difference to matter. I do not know that. What I do know, from trumpet technology, from building Native American Flutes and from researching the science of sound, is that increasing mass = more power.
In a tennis racquet, the more weight you add to the frame, with the same swing speed and ball weight, the ball will travel further on impact. Mass = power. In trumpet technology, more mass = power, more projection. Standard trumpets, factory made, sound great to audience and player alike. That is because the horn is relatively light and as a result the entire horn vibrates while producing notes... sending sound waves in all directions, not just outward from the bell. Because the sound waves emanate in a spherical wave, the trumpeter is able to hear himself play and adjust tone etc.
When trumpet mass begins to increase, the horn itself starts to vibrate less. End result is the sound is more projected outward via the vibrating air column, exiting the bell. The audience may not hear a difference early on but the trumpeter begins to hear himself playing less and less.
Eventually, as the horns mass continues to increase, the trumpeter finds it difficult to hear himself playing, difficult to adjust tonal qualities on individual notes while the audience is hearing the sound loud and clear, and what's more, with greater intensity because the vibrations that had previously leaked away in all directions through the horn, are now scavenged and focused into the mainstream, directed outward thru the bell.
When mass is added to the guitar, anywhere but on the soundboard, the ability of the strings to vibrate the air volume under the soundboard doesn't change, except for possibly vibrating longer as one poster suggested. The air volume under the soundboard vibrates pretty much the same as usual and causes the resulting vibration on the soundboard - this is like a sound pump. Since less vibration is allowed to migrate through the rest of the guitar, more of it is amplified through the soundboard and air column = more volume, more tone from sound hole and soundboard.
Mass in musical instruments, when used correctly, is about dampening vibration where it takes away from volume, projection and tone. I don't think this matters much for amped guitars (fat finger = hype). It matters for acoustics (fat finger = help). These are my thoughts. |

Location: Utah | I'm going to weigh in with tdeej's argument. Adding mass to the end of the neck will make it more difficult for the neck to vibrate. Neck vibration will waste energy. So, the neck is "stiffer" and more energy is transmitted to sound, and the string vibrates longer.
Just a guess, but it makes some sense. Is it enough of a difference to hear? That's a whole different issue. |

You can disagree with me, but take it from someone who actually colored the edges of all his CD's with special green felt sharpie pens, I know marketing spew when I see it.
