A Bottleneck Designed for Precision and Musicality
The Jim Dunlop ADU 912 Mudslide Hybrid is aimed at guitarists who want to combine two complementary tonal signatures in a single accessory. Its hybrid design blends the clear, singing attack typical of glass with a denser, warmer texture inspired by ceramic. The result: a responsive guitar slide capable of shifting from crystalline phrasing to thicker lines, ideal for blues, rock, country, or open tuning chords.
Thanks to its controlled weight, it quickly becomes unnoticeable and promotes relaxed playing, even during long takes: you maintain precision in micro-movements, vibratos, and note endings without tension. Its stable grip helps maintain consistent contact with the strings for smooth slides and easier intonation control. A relevant choice if you're looking for an all-around bottleneck that remains musical on both electric and acoustic guitar.
