Its generous dimensions and weight help you anchor your tone, delivering crisp string clarity without harshness, even during aggressive picking or expressive vibrato.

Practical tips to get the most from your slide:

• Pair with standard tuning or open tunings to explore the slide’s emphasis on midrange harmonics, then compare clean single-note lines against chordal voicings for a fuller sound.
• Keep the edge smooth and free of burrs with a soft cloth; clean regularly to maintain clarity and brightness of the glass.
• Store in a protective case or pouch to preserve the polished edges and prevent chipping from accidental drops.

In short, the Jim Dunlop 213 Glass Slide — Large/Heavy — combines a time-tested Pyrex glass voice with a substantial, comfortable grip. It’s a durable, reliable choice for players who value tone solidity, midrange focus, and enduring performance from a single, purpose-built slide.
