One of the key components of any guitar is it’s nut. It is one end of the vibrating strings that make the instrument produce sound. It affects how the instrument sounds, not only regarding tone and timbre, but also pitch. The strings tension is effectively maintained between the tuning machine and the tailpiece, bridge, or body, while the nut and bridge produce the scale [length]. It’s important that the strings move freely through the nut slots. If the tension is lower or higher behind the nut because of friction between the string and nut slot, the string can at any time slip (jump) through and change the pitch while you are playing. This imbalance in tension can happen while tuning, bending strings, using a tremolo bridge, or due to humidity or temperature changes. How frustrating it is to be tuning and while raising the pitch of a string, have it jump up and go past the correct pitch.
Much of the key to easy and stable tuning is having a quality nut material with properly sized slots for your string gauges that are lubricated. When the string is free to maintain equal tension on both sides of the nut, you’ll get the most stable tuning and it will be easy to achieve. Quality tuners with smooth action will also make a big difference.
If you have tuning problems with your instrument, I can almost certainly help. Having a quality nut made or having your quality nut properly fitted is one of the first/best improvements you can make to your guitar. I stock natural and synthetic nut materials.
I finally tried Big Bends Nut Sauce and I wish I hadn’t waited so long. I really like it. I’ve tried various nut lubricants before, but I don’t think any of them are as slippery as Nut Sauce. Plus, it’s clear, so it doesn’t violate your nut or fingers. Big Bends Nut Sauce.
