I bought this strap from a TB'er back in July and after trying it out for a couple of gigs decided it didn't work for me. I'll let it go for what I paid for it....$30.00 firm shipped CONUS, PayPal.
Here's the original thread I got it from; Mono Betty Strap in Black
The strap is still in excellent condition, near new. The only marks on it are faint lines on the strap button pads. The front pad shows where I had a Dunlop strap lock mounted although there are no indentations in the pad. And the rear pad has a faint mark from the rear strap button on my P-bass...and again no indentations. Other than that, the strap is in new condition.
