Dunlop Ultex Jazz III XL 1.38mm 6-Pack - Precision Control for Fast

In this review the Dunlop Ultex Jazz III XL 1.38mm 6/Player's Pack is assessed as a pick for players who want the bite and speed of a Jazz III with a slightly larger, more familiar profile. The bottom line: this pick is for guitarists who prioritize control and attack without giving up comfort. The review finds the Ultex material delivers a lightweight, rigid feel and the molded quick release edge produces a tight, articulate attack that helps build picking speed while remaining comfortable for bigger strokes.

Key Features

• 1.38mm gauge: Provides a stiff, consistent thickness that favors precise, punchy attack and stable picking dynamics.
• Ultex construction: A lightweight, virtually indestructible material that keeps tone bright while resisting wear.
• XL Jazz III shape: A larger profile than standard Jazz III picks to suit players who prefer a more standard-sized pick without losing the pointy tip control.
• Molded quick release edge: The shaped edge lets the pick glide off the string for faster, cleaner picking and improved articulation.
• Raised logo grip: Textured logos on both sides improve purchase and reduce slippage during fast runs or strumming.

Who It's For

The Ultex Jazz III XL is ideal for lead players, shredders and hybrid pickers who need a rigid pick that produces pronounced attack and fast release. It suits players moving between single-note runs and aggressive strumming who want the Jazz III point but with a fuller feel.

Players who want a very flexible or rounded pick for heavy rhythm strumming or those who prefer thicker, softer materials for warm, mellow tones should look elsewhere. Also, if you need a variety pack of gauges, this single-gauge 1.38mm offering may be too specialized.

Pros & Cons

Pros

• Excellent control and speed from the stiff 1.38mm Ultex material that barely bends under force.
• Oversized Jazz III shape gives familiar handling while maintaining the sharp tip for definition.
• Durable, lightweight construction and molded quick release edge for bright, consistent tone and fast picking.
• Raised logo grip on both sides prevents slippage during extended playing.

Cons

• The stiff 1.38mm gauge can feel unforgiving for players who prefer softer, more flexible picks for rhythm work.
• Offered only in the single 1.38mm thickness in this pack, so it lacks gauge variety for those experimenting.
