String winding
Fast changes. Clean winding. Reliable tuning.
The right string path helps every automatic tuner work faster and more consistently.
Choose your String Lock
SLS — String Lock System
Feed the string straight through, lock it mechanically and cut the excess. No traditional wraps are needed.
Standard Lock Nut
Use a clean winding pattern with minimal, tidy wraps. Avoid crossing the string over itself.
SLS in four steps
1. Tension the string and make the lower half-turn
Keep the string under tension by hand. Wind it around the lower recess of the string shaft by half a turn — never more than one complete turn.
2. Guide the string to the upper recess
Lead the string through the slot from the lower recess to the upper recess of the string shaft while keeping it tensioned.
3. Bend and secure the string
Guide the string through the upper slot and bend it firmly. For thin strings, form a figure-eight around the slot so the string locks securely.
4. Trim the remaining string
When the string is seated and secure, clip off or shorten the remaining end to the desired length.
Standard lock: bass side
1. Tension the string and make the lower half-turn
Keep the string under tension by hand. Wind it around the lower recess of the string shaft by half a turn — never more than one complete turn.
2. Wrap clockwise around the thread
Guide the string upward through the slot. Wrap it once clockwise around the thread; use two turns for thinner strings.
3. Tighten the string with the Locknut
Do not use a screwdriver. Tighten the Locknut by hand; hand-tight is normally sufficient.
4. Trim the string
Once the string is securely locked, shorten the remaining string end close to the post.
Standard lock: treble side
1. Tension the string and make the lower half-turn
As on the bass side, keep the string under tension by hand and make half to a maximum of one turn around the lower recess.
2. Wrap around the thread in the mirrored direction
Guide the string upward through the slot. Follow the mirrored treble-side direction shown in the photo: one wrap, or two wraps for thinner strings.
3. Tighten the string with the Locknut
Do not use a screwdriver. Tighten the Locknut by hand; hand-tight is normally sufficient.
4. Trim the string
Once the string is securely locked, shorten the remaining string end close to the post.
5. Tighten carefully only if necessary
If required, tighten the Locknut slightly with a 1-cent coin. Never use a screwdriver — excessive force can damage the gear wheels inside the PowerHead.
