Description Two replacement locking knobs for HD988 locking 1:21 Journey tuners found on Overhead and First Class collapsible travel guitars. If these are not tightened, they can come unscrewed and fall out, so we offer replacement locking knobs here. The benefit to our locking tuners is that you don’t need to wrap your string wire when you change your strings, which saves time and ensures better intonation when you frequently remove and reassemble your guitar neck. Pictures of headstocks and full tuner sets are for reference only. When you order this component you’ll only receive two replacement locking tuner knobs. Be sure to always fully tighten the locking knobs whenever you change your strings.
