In this months newsletter, Rodney Gene says that using a spacer on the B or E string, before the bridge (see diagram) will help "increase tension" on said string. Since the speaking length of the string (only the area between the nut and the bridge saddle) is the only thing, other than string gauge, that dictates the tension needed to achieve the desired pitch, messing with the lengths after the nut and bridge saddles to the various anchor points are irrelevant to the tension needed to reach the desired pitch on a given scale (speaking length) with a given string. I've seen a similar thing touted in various bass designs (i.e. Having a B string post that is farther from the nut or a ball end anchor point that is farther from the bridge saddle) as a "way to increase tension" but, from a physics angle, this is not possible because to increase tension on a given (pitched) string without increasing scale is impossible, regardless of where the string is anchored after the nut or bridge saddle. This does not apply to tone differences due to types of anchor points (i.e. String through body vs. through bridge) since the given string on the given scale is still tensioned the same on it's speaking length. Rodney Gene's mod may or may not help tone, but tension along the speaking length of the string will not change. All this mod will do is place the speaking area of the string up some distance. The speaking area's size will remain unchanged. However, this mod may make it difficult or impossible to get said string's windings over the nut due to the entire string being shifted towards the butt end of the bass unnecessarily. Any opinions on this?
