Question ? Propos De L'intonation Sur Les Chevalets Epi / Gibson


Recommended Posts

Posted

En trainant sur un forum US, je suis tomb? un article selon lequel le fait que le tissu ? l'extr?mit? des cordes soit en contact avec les pontets est problàmatique :

Intonation problems on Gibson basses are not just confined to the past. The silk windings on the ball-end of certain brands of string must not touch the bridge saddle, as this will affect proper string vibration, and intonation. This is not a problem with all strings, or basses that can be strung through the body, and sometimes cutting back the windings can be enough to prevent this. Sometimes this isn't the case. Luckliy engineer Evan Webb has come up with a simple and inexpensive solution designed for the Gibson/Epiphone three-point bridge, allowing you to use the strings you want. This mod will work on all three-point bridges (in use by Gibson since 1973) but is not recommended for the earlier two point model (although we could certainly use one!)

L'article est ? propos d'un syst?me simple invent? par un gars pour am?liorer ce chevalet :

CITATION
The Mod Bar was designed to fit under the 3 point Gibson and Epiphone bass guitar bridges. The bar is made from high grade polished 304 stainless steel bar stock that is 3/8 inch diameter. Its precision drilled to match the bridge string spacings. All you have to do is thread the strings through and tuck it under the string claw as seen in the photos. Tune up, intonate if needed and enjoy the new sound of your bass. The bar should be able to get the silk windings and/or rough end string construction out of the way and will prevent them from resting on the saddles. That alone gives you a better sound, but thats not all ! The heavy stainless steel bar increases the bridge mass by 1/4 its own weight and also makes a better string to bridge touch ratio. A big solid bar has way more surface contact then little ball ends of a bass string. With the extra mass is greater string to saddle pressure! The Mod Bar moves the string end at an increased downward angle and that will always equal better sound!

Donc voilà, il y a sur ce forum quelques utilisateurs de T-Birds, Rivoli et autres EB basses, est-ce que vous avez le même genre de souci et que pensez-vous de ce truc ? D'ailleurs est-ce que c'est un souci sp?cifique ? ce type de chevalet ?

C'est un soucis que j'ai déjà eu sur quelques basses vintages europ?enne. Pas sur les rares EBX que j'ai vu passer. Mais c'est vrai : il ne faut pas que le tissu ou l'enroulement de la boule repose sur le pontet, ?a peut poser des problàmes. Les deux solutions que j'ai utilis? jusque là et qui ont suffit :

- Labella supersteps

OU

- découper un peu du tissu

La solution propos?e sur l'article est intelligente et ?làgante, je note.

Apparemment le gars vendait sur Ebay mais il semble que ?a ne soit plus le cas, cela coûterait combien de fabriquer ceci selon toi ?

?a risque de faire un peu vilain avec un tube en laiton quand-même :rolleyes:
