The following information will allow you to keep your Conklin instrument in top condition.
Start by getting your action or string height where you want it. We usually lower the strings to about 1/16"-1/8" above the last fret viewed from the side of the fingerboard. The strings are lowered by using an allen wrench to back out the hex screws in the bridge saddles. The screws should be let out evenly so that the saddle remains level and not tilted to one side or the other. Once the saddles have all been lowered, the relief in the neck should be checked. This is easily done by pushing down the lowest string at the first fret and at the last fret with the first finger of each hand. View the amount of space under the string at about the 9th fret from the side of the fingerboard. There should be about a 1/32"-1/16" gap between the string and the fret. If there is too much space under the string (concave condition), you will need to loosen the strings and tighten the truss rod(s) by using the proper sized allen wrench to turn the rod to the right. Make sure the string tension is loosened prior to tightening the truss rod(s) or the rod could be damaged. We recommend a 1/4 turn at a time on the rod(s) and then a re-check of the neck relief as described above. If the neck is backbowed(convex) or too flat, the rod(s) will need to be let out by loosening the truss rod(s), again about 1/4 turn at a time. After the proper neck relief has been achieved, retune the instrument and check to see that each string plays out along the full length of the neck without fret-outs. If fret-outs are encountered, you will need to raise the bridge saddle for those strings until the fret-out is alleviated. As you are adjusting each saddle to its final heighth try to get the strings to match the radius of the fingerboard and frets with the two outer strings at the lowest position and each succesive string being set slighter higher with the center string at the highest position when viewed from the side of the fingerboard. This will assure that the strings are as comfortable as possible to play.
The figerboard can be kept conditioned with boiled linseed oil available at your local hardware or home center. There are also products available through your local music store such as "Dr. Ducks AxWax" or "Fretease", which can be used on the fingerboard and strings.
The body can be wiped down and polished with any guitar cleaner/polish that does not contain silicone.
Finally, we recommend that you take your instrument to a local guitar repair tech about every six months to a year for a check-up and intonation adjustment to ensure that your Conklin is always operating at peak performance.
