FenderFatfinger Guitar Sustain Enhancer
1/3
Independent shopping perspective
The Korena take
A clamp-on brass weight for the headstock that adds mass to change how notes sustain. For players chasing dead spots on a bolt-neck instrument.
Strong match
Who this is for
- Killing a dead spot on a Jazz Bass or Strat neck
- Testing mass changes without permanent modification
- Players who move between instruments and want it portable
Consider the trade-offs
When to look elsewhere
- Anyone expecting a compressor or sustain pedal effect
- Headstocks too thick or oddly shaped for the clamp
- Players who dislike added weight and neck dive
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.
Detail 02
Added headstock mass
Shifts the neck's resonant frequency. Dead spots move to a different note rather than disappearing entirely.
Detail 03
Position is adjustable
Sliding it along the headstock changes which note is affected. Finding the right spot takes experimentation.
Detail 04
Mechanical, not electronic
Nothing to power, nothing in your signal chain. Works the same acoustically and plugged in.
Final check
Know before you order
- 01Check your headstock thickness fits the clamp before ordering
- 02Adds weight where you least want it — expect more neck dive
- 03Effect is subtle; it relocates dead spots more than it removes them
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this actually increase sustain?
It changes how the neck resonates, which can lengthen notes that were dying early. It's a targeted fix for dead spots, not a broad sustain boost.
02Will it damage my finish?
It clamps rather than attaches permanently. Keep the contact surface clean and check periodically that it hasn't shifted and scuffed the headstock.
03Bass or guitar?
Both, as long as the headstock fits the clamp. Bass players use it more, since dead spots are more common on long-scale necks.
04Where do I put it?
Start near the tuners and move it while playing the dead note. The right position varies by instrument, so plan on trial and error.
