Martin Style Compensated Bone Guitar Saddle *** MANY SIZES POSSIBLE: If you have a different size, that is not shown in the choices, then please just send us an eBay message of your sizes. **** The Materials This saddle is made from high density Ox bone and is for use on steel strung acoustic guitars. These saddles are renowned to give excellent tone, playabilty and instrument projection. The saddle can be made left or right handed Saddle Dimensions Choices For many Martin guitars using these saddles, typical dimensions are : Length: 74mm; Width: 2.5mm; Height: 9.0mm; Radius: 16 inches. However, our expereince has shown the requirments for variations on these dimensions due to obvious ageing affects on guitars and player preferences. To position the crown features I assume an E to E at the saddle of 55mm - if your guitar has a significantly different E to E at the saddle please let me know. Width: Please select the width to ensure a good fit which will benefit the tone. I can provide the saddle width to a maximum of 3.5mm thickness. Height: I can make the height to a maximum of 10mm (and as low as about 3.5mm). The height of the saddle will determine the action (fret to string distance) - this should be about 2.6mm for low E string at 12th fret and usually a bit lower for high E string at 12th fret. A useful fact is that a change of saddle height by a certain amount - 1mm reduction for example, will make a change of half that amount - so 0.5mm at the 12th fret. Length: I can provide the length up to 79mm The length should fit the saddle slot and I make the ends rounded. Radius: Typically Martin guitars with this type of saddle are a 16" radius. Fretboards for steel strung acoustics are generally curved from low E to high E - this makes it comfortable to play. The curve follows a radius and is part of a big circle. The strings must sit close to this curve so you press them down onto the fretboard easily - but if they are too close you will get a rattle. Hence the saddle - and the nut - also follows this curved profile so the strings nicely sit just above the fretboard. The radius is expressed in inches usually and is typically 12", 14 ", 16" 18" 20" or 24" - the bigger the radius the flatter the fretboard. Action Drop Off: The thicker the string the more room it need to vibrate and so the low E is positioned a little further away from the fretboard compared to high E - the difference is only about 0.5mm at 12 fret which is brought about by a slight change of 1mm to 1.5mm in saddle height from a perfect circle profile - usually saddles can be seen to be a little lower at the high E side. Compensation Shape This saddle compensation design has the string contact points of The Low E string is set back The ADG string are set forwards The B string is set back The Upper E string is in the middle. Please see photo on this listing to see the string contact line. Please note that NON-COMPENSATED Martin saddle are dealt with by another of my ebay listings.

FREE : A choice of the length, width and height to fit your guitar How a Compensated Saddle works Acoustic guitar saddles are often shaped to provide 'compensation' - which results a better sounding and more accurate pitch of the fretted notes. The length of each individual string is altered by adjusting the string contact point at the saddle. In turn this alters the pitch of fretted notes. On most guitars fretted notes may not vibrate at exactly the ideal pitch (a chromatic tuner will show this). This is due to a variety of effects such as the strings stretching when pressed down into the fret. Saddle compensation design helps to adjust the pitch of the fretted notes to be closer to the ideal. The closer the pitch of the fretted notes is to the ideal will result in better sounding harmonies between notes (better sounding chords) and a guitar that is more in tune all the way up the fretboard. Quality Control We perform many quality control checks during manufacture and prior to dispatch to ensure that you receive a saddle that fits your guitar to your specification. Essentially the better it fits - the better it sounds! It is highly polished - especially where the strings contact it.
