Independent shopping perspective

The Korena take

Chrome tuner upgrade kit for guitars with 6mm mounting posts. For players fighting tuning slip on a guitar that's otherwise fine.

Strong match

Who this is for

  • Guitars whose existing tuners have 6mm post holes already drilled
  • Players who retune constantly between songs or tunings
  • Restoring an older guitar without enlarging headstock holes

Consider the trade-offs

When to look elsewhere

  • Headstocks drilled for 8mm or 10mm posts — wrong fit
  • Anyone wanting gold or black hardware to match existing parts
  • Players whose tuning problems come from the nut or strings

What matters in use

The specifications, translated

Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Graph Tech Supercharger Kit NV2 for 6mm Posts Chrome construction detail

Detail 01

6mm posts

Fits headstock holes bored to 6mm. Measure your existing hole before ordering — post diameter is not adjustable.

Detail 02

Chrome finish

Bright silver. Matches chrome bridges and jack plates; will look off next to gold or black hardware.

Detail 03

1-23/32 inch length

The footprint on the headstock face. Check against your current tuner plates so old screw holes stay hidden.

Detail 04

11/32 inch height

How far the housing stands off the headstock. Low enough that it won't foul most cases or gig bags.

Detail 05

1/4 inch thickness

Baseplate depth. Thin plates sit flush; thick headstock finish edges can leave a small gap.

Final check

Know before you order

  1. 01Measure your headstock post holes with calipers — 6mm only, no shims included
  2. 02Old screw holes may not line up; you may need to plug and redrill
  3. 03Restring and stretch new strings before judging whether tuning holds

Product questions

Before you decide

Straight answers to the questions shoppers most often ask about this product.

01Will these fit my Strat?

Only if the headstock holes are 6mm. Many modern Fenders use 10mm vintage or 8mm bushings. Measure the hole, not the string post, before ordering.

02Do I need to drill new holes?

Not for the posts if yours are already 6mm. Mounting screw holes may not match your old tuners, in which case plugging and redrilling is needed.

03Is chrome the same as nickel?

No. Chrome is brighter and cooler-toned. Next to aged nickel hardware the difference is visible, especially on the headstock where both sit in one plane.

04Will this fix my tuning problems?

Only if the tuners are the cause. Binding at the nut, bad string winds, or a worn tremolo will keep slipping tune regardless of what tuners you install.
