Dunlop Chromed Steel Slide : Tionline's user review

has been 5 years since I use this bottleneck, and it still looks as new. That's the advantage of metal.
However, if it is solid and has lasted a lifetime, even when the sound is much more aggressive and ... mtallique with a glass bottleneck.
N'tant not a specialist in this type of game, I'm perfectly happy and if I buy a bottleneck, it would suit me perfectly.
