A brass slide designed for resonance and feel
The Dunlop 227 is a brass bottleneck crafted for guitarists seeking a denser sound, with pronounced presence and warm mids. Its medium/heavy weight promotes consistent pressure on the strings, helping to achieve generous sustain and more stable intonation, especially on the singing phrases typical of blues and rock riffs played in slide.
Its concave shape provides excellent comfort: the finger naturally settles in, facilitating control over dynamics, micro-vibratos, and quick transitions between notes. Whether you play in open tuning or standard tuning, this bottleneck quickly becomes a reliable ally for dynamic, precise, and musical playing.
