Detail 01
1.0 mm thickness
Mid-heavy. Barely bends, so pick angle and hand pressure control the dynamics instead of the pick itself flexing.

Dunlop421P Ultex Guitar Picks 1.0 mm 6-Pack
Independent shopping perspective
The Korena take
Six 1.0 mm Ultex picks in yellow. A stiff, hard-wearing pick for players who want minimal flex and a bright attack.
Strong match
Who this is for
- Rhythm players who dislike pick flex on hard downstrokes
- Fast single-note lines needing a firm, controlled attack
- Anyone tired of picks wearing round after a few weeks
Consider the trade-offs
When to look elsewhere
- Light acoustic strumming — 1.0 mm feels stiff and clacky
- Players used to thin picks; the change is abrupt
- Anyone wanting a warm, soft attack off the 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.
Detail 02
Ultex material
Harder and slicker than nylon or celluloid. Brighter attack, sharper transient, and it holds its point far longer.
Detail 03
Yellow color
Easy to spot on a dark stage floor or inside a gig bag pocket when you drop one mid-set.
Detail 04
6-pack
Enough to keep spares in your case, pocket and on the amp, since picks disappear rather than wear out.
Detail 05
Standard pick shape
Familiar outline with a moderate tip, so it works for both strumming and single notes without retraining your grip.
Final check
Know before you order
- 01Ultex is slick — hands that sweat may want a grip pick instead
- 02If you play 0.60 mm now, 1.0 mm is a large jump
- 03Bright attack is more noticeable on acoustic than through overdrive
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is 1.0 mm a heavy pick?
It sits in medium-heavy territory. Thin picks run 0.5 to 0.7 mm, heavy picks 1.5 mm and up. At 1.0 mm there is very little give.
02How does Ultex compare to nylon?
Ultex is harder and more slippery, with a brighter, more defined attack. Nylon is grippier and warmer, but wears down and rounds off faster.
03Will these work for bass?
Yes. At 1.0 mm the stiffness suits bass strings, though many bassists prefer something thicker still for a firmer attack on heavy gauges.
04Do they get slippery?
Ultex has a smooth surface with light texturing on the face. If your hands sweat heavily, a picks with a raised grip pattern holds better.
