Guitar Picks Explained: Shapes, Materials & Thickness

A guitar pick may be tiny, but believe me--it is huge in the way it sounds and feels. As a beginner or an experienced player, knowing the fundamentals of the types of guitar picks, materials, and thickness can lead you to new dimensions of tone and control.


Guitar picks aren’t just tools—they’re tone-shaping instruments in their own right. As Strings and Beyond explains, different pick materials (like celluloid, nylon, or Delrin) dramatically alter brightness, attack, and grip, while thickness influences precision and fullness of sound—thin picks offer flexibility and brightness, whereas thicker picks deliver control and depth 


This guitar pick guide breaks down everything you need to know. Plus, you’ll get the scoop on two top-tier options: the 5 Core 0.96mm Celluloid Heavy Gauge Pick and the broad lineup from D’Addario, a brand that’s been shaping tone since forever.

Why Pick Shape Really Matters

Let’s start with shape, because the contour of your pick dictates how it meets the strings—and that profoundly affects your attack and comfort.

  • Classic Teardrop: The most common shape, offering a balance between smooth strumming and precise picking. Comfortable in most hands, it’s versatile across genres.

  • Jazz Picks: Smaller and pointier, jazz picks offer precision for intricate lead work and fast runs. If you like defined attack and tight control, this is your shape.

  • Triangle Picks: Big, comfortable, often preferred by bassists for their grip and coverage on thick strings.

  • Sharp-Point Picks: Lead players and shredders often opt for these for the sharpest attack and tightest articulation.

Experimenting with shapes lets you find your unique pick “sweet spot”—where your hand flows easily and your tone blooms.

Materials: How Your Picks Makeup Colors Your Sound

Not all picks are created equal; the material shapes more than feel—it influences tone and durability.


  • Celluloid: The vintage classic. Loved for its natural warmth, smooth glide, and flexible touch. 5 Core’s celluloid picks, especially their 0.96mm Heavy Gauge option, deliver that buttery smooth feel combined with the stiffness needed for precise attack. These picks fit perfectly for players wanting a warm acoustic or electric sound with extra grip and durability.


  • Nylon: Offers good grip and a bright, articulate sound with some flexibility. Nylon picks last long and are favored by dynamic players needing expressiveness.

  • Delrin (and its Variants): Known as D’Addario’s “Black Ice” picks, these boast a matte finish with great grip, durability, and a distinctive bright tone. Delrin feels slick but offers excellent control once you get used to it. D’Addario’s variety pack includes them, among others, which makes it a starter’s dream and a pro’s reliable toolkit.

  • Other Materials: From metal to felt or even stone, these offer niche tones but often less versatility.

Thickness: The Magic Number Behind Your Tone and Control

Thickness or gauge often determines whether your pick is buttery soft or rock-solid.

  • Thin Picks (~0.5mm): Super flexible, great for smooth strumming and softer dynamics. Acoustic players love these for warm, round tones.

  • Medium Picks (~0.7mm): The sweet spot between control and flexibility—great for hybrid styles.

  • Heavy Picks (~0.9mm and up): These are stiff, precise, and perfect for players who want sharp attack and fast lead work. The 5 Core 0.96mm picks fall here, giving those who want thick picks a natural feel without compromising on tone.

  • Extra Heavy Picks (1.2mm+): Usually for specialized lead guitar or bass playing where maximum control and accuracy are key.

When testing picks, try to match your playing style—fast strummers will want more give, while aggressive lead players thrive with heavy picks.

Why 5 Core’s 0.96mm Celluloid Heavy Gauge Picks Stand Out

5 Core’s picks are a standout because they combine the vintage warmth and glossy feel of celluloid with a thickness that gives you serious control. The 0.96mm gauge means it’s solid enough for fast leads and heavy-strumming rhythms alike.

They provide great grip and balance pick you will not struggle to hold or fear of flipping in the middle of a solo. This renders them ideal for electric and acoustic guitar, and even bass players seeking a fatter pick to articulate with.


Players boast of their longevity and the same tone- this makes them a sure shot on stage, in the studio, or in long practice sessions.

D’Addario Picks: The Go-To 

D’Addario has long been a household name for guitar strings—but their picks get serious love, too. They cover every major material and shape, giving players tons of options.

Some highlights include:

  • Celluloid Picks: For warm, vintage tone lovers.

  • Delrin “Black Ice”: Matte finish for better grip and bright, crisp attack.

  • Duralin & Nylpro Picks: Engineered for durability and smooth string glide.


The advantage? D’Addario also has variety packs to allow you to test without commitment. Their selections frequently get preferred by both major artists and studio professionals because of the feel, durability and capability to perform in a wide variety of playing styles.

How to Choose Your Best Guitar Pick: Quick Tips

  • Match your pick thickness to your style. Heavy for leads, medium for versatility, light for soft strumming.

  • Pick a shape that matches your grip and playing comfort.

  • Consider picking a celluloid pick for warmth or a Delrin variant for durability and brightness.

  • Don’t hesitate to try variety packs before settling on your go-to.

Conclusion

Your pick is a bigger player than you think. The right shape, material, and thickness unlock new colors in your playing that can set you apart.


If you want tried-and-true warmth and control, the 5 Core 0.96mm Heavy Gauge Celluloid Picks are worth a serious look. For players who appreciate choice and pro-grade innovation, D’Addario’s wide range of picks offers exactly that.
