What matters in use
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 01
Warmer and rounder than metal. Less string noise and less zing, at the cost of sustain and volume.
Detail 02
Tapered like an actual bottle neck rather than a straight tube. Flare sits over the knuckle, narrow end at the tip.
Detail 03
Fits a narrower finger. Too loose and it wobbles; too tight and you cannot get it on.
Detail 04
Added mass helps the slide sit on the strings and sustain rather than chatter.
Detail 05
Slips over the finger and stays there. You can still fret with the remaining fingers.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.

Glass is warmer and smoother with less string scrape. Metal is brighter, louder and more sustaining. Glass is the traditional choice for blues.
Yes. Glass slides work on electric and acoustic. Electric setups with low action may need the action raised to avoid fret buzz.
It should slip on with slight resistance and stay put when you point your hand down. If it spins freely, size up.
