For your reference, provided below are a standard or "traditional set up" copedent chart, a blank copedent chart, and a chart for players who want tandem and/or additional center knee levers. Likewise, we have received requests for publishing a rodding chart, so that has been provided too. If you are ordering a new Williams, an accurate copedent chart is essential for us, so that we can rod and set up your guitar properly. If you have any questions on how to fill out a copedent chart please contact us, and we will be happy to assist you.
