Secure and Reliable Strap System for Peace of Mind

LexQ 17.11.2025

bought the Ibanez ISB4-BK to improve the security of my guitar strap during rehearsals and gigs. The construction feels solid and the locking mechanism engages firmly without any wobble. Installation was quick and straightforward. Once mounted, it keeps the instrument completely stable, even when moving on stage or practicing standing for long sessions. The finish matches well with most guitars and does not look bulky. A great upgrade for anyone who wants a trustworthy strap locking system. Excellent value for the price.

Great quality, but a bit loose

tteeem 10.08.2026

Out of the packet, the quality is amazing. It's a good material and a solid colour. The only issue I found with it is that, when putting one on your guitar, it feels like it goes on way too easily. It feels too loose. It's been holding up on my telecaster for about a week with no issues, but I'm keen to try them out on a heavier guitar, like a Les Paul or a bass.

I use these or similar products on every guitar and bass I own. Has worked out perfectly for years, and are muxh cheaper than strap locks.

Solide Blocker

Kosmodroneout 28.06.2023

Um ehrlich zu sein: So viel unterscheiden sich die Ibanez Strab Blocker nicht zu den Modellen von Harley Benton, Fender, etc. Warum auch? Am Ende ist es ein solide gefertigter Gummiring, der tolpatschige Musiker:innen vor Kosten und Gram schützt.

Würde ich wieder kaufen.
