Will buy more
Style: Locking Color: Black
This has become my son’s favor guitar strap over some that were much more expensive. Plus it secures some pretty expensive guitars to make sure nothing bad happens while he’s playing.

Just as expected
Style: Locking Color: Black
The locking mechanisms work well. No concern of the wiggling loose.

The best!
Style: Locking Color: Black
I LOVE this strap. I’ve used a lot of straps touring around the country for a decade, and this is THE ONE. Simple, safe, comfy, everything you need. It’s way longer than anyone alive would ever need, but that’s just nit picking.

Favorite strap
Style: Locking Color: Black
This is by far my favorite strap for my bass guitar, slides on and off easily, and once it is on, you know it’s not going anywhere…. Great purchase, highly recommended!!!!

Don’t trust these
Style: Locking Color: Black
Don’t trust these to secure your guitar from falling to the ground. My brand new Strat is now dented on the bottom because the leather stretched and came loose. I’ve had this for a couple months so it’s not that it just needed replacement. I’ll never buy these again and looking to replace them or find another solution that does not require me to remove a screw from the guitar. Ernie Ball should replace my guitar but that’s a whole different thread. ... show more

Great strap.
Style: Locking Color: Black
This thing works great. So good that my dad stole it for his guitar and I never got it back. I will most likely be buying another one.

No MAY NOT But DOES NOT Work on SG Guitars
Style: Locking Color: Black
Well-made strap. The locking ends feel secure and durable. The ad reads "may not" work on certain styles, including SG. Absolutely DOES NOT work on the SG style. For an SG, the strap has to have a twist in it for the locking ends to go on correctly. So - decent strap - locks securely - just annoyed at their ad copy when they KNOW that it doesn't work on SG setups. ... show more
