Furthermore, because slotted-head string posts go through a pair of holes instead of just one, there is twice the potential for such fitting and friction problems. These holes can sometimes get filled in with stray lacquer during finishing, or have rough interiors left behind after drilling, both of which can cause added friction and interference. Instead, most slotted tuners simply live in holes drilled in the wood itself. They cannot easily be installed in bushings (the small metal cylinders that support the string post on solid pegheads). When this happens, the strings cannot travel freely through the nut as you tighten or loosen the tuners-another very common cause for tuning issues.Īt the design level, tuners for slotted headstocks have a challenge to overcome. On occasion, particularly with softer nut materials, this pressure can cause wound strings to grab and dig into the nut material and bind up. This results in greater downward pressure on the nut itself. Slotted headstocks typically have a steeper break angle beyond the nut. Although it’s not the fault of the design itself, it takes a more careful approach to string correctly. Regardless of tuner or headpiece type, the strings should be wound with each wrap nice and snug against the adjacent ones, without crossing windings, and no more than three or so wraps for wound strings, and maybe four or five for plain strings.ĭue to the design of slotted headpieces, the posts are more difficult to reach and the strings are harder to control as they are brought up to tension, so I often see more of these kinds of winding issues with slotted headstocks. In these cases, residual slack can be stored in the windings, and can slowly settle over time, causing tuning instability. Frequently, this goes along with excessive amounts of string wound around the post, which can cause the string to pile up, cross over itself, and not wind tightly around the post. On the repair bench, I often encounter strings that are not wound evenly and neatly around the string posts. To begin, let’s consider some of the more common headstock-end causes for tuning problems. It serves well to illustrate the universe of little details that can exist within an apparently simple feature such as the headstock shape. #Slotted lin etuner seriesDo they stay in tune as well as guitars with solid headstocks? -Jeff Fitzpatrick, Dexter, MOĬheck out more articles from our Ask The Expert series hereĪ: Great question. Q: I’ve never had a slotted headstock guitar. The slotted line is used to measure the voltage standing wave ratio of the transmission line upto the frequency in GHz.From the July/August 2020 issue of Acoustic Guitar | By Martin Keith #Slotted lin etuner freeWhere V stand for velocity of electromagnetic waves in free space equal to 3 X 10 8 ms. The distance between those two points provides us the wave length equal quarter λ frame which we can calculate the operating frequency using the formula We mark the point for maximum and minimum voltage reading. To measure the frequency of the transmitter with the help of slotted line, the scale is provided at the device. It should only be electrically coupled with the energy passing through the transmission line.įor measuring of voltage standing wave ratio we take the maximum and minimum reading of voltage along the transmission line by moving the probe right and left and locating at the SWR indicator. We are to adjust the probe should not touch the conducting wire of transmission line. Whenever we want to measure the voltage standing wave ratio of the transmission line, we are to place the conducting wire of the line inside the slotted line through the slot provided in that device. ![]() The transmission lie is kept inside the slotted line for measurement of values of maximum voltage point and minimum voltage location. ![]() The output of the probe is provided to standing wave indicator in order to measure the voltage standing wave ratio. The test probe is kept inside the slot in such a way that it is parallel to the electric field and the transmission line. As shown in the below diagram, the slatted line consists of minimum λ/2 piece having a slot in its longitude and a circular shape internally. ![]()
