Dave Navarro can go from shredding to bedding in one fell swoop … now that he’s designed a two-in-one guitar strap slash sex toy.

The rocker tells TMZ he decided to combine his 2 favorite things — music and sex — and teamed up with a BDSM toy company … and the result is something he calls, “The Strap.”

Pretty simple concept … the guitar strap comes off the guitar and can then be used to restrain yourself or a partner in a ton of different positions. Seriously … just about anything your sick mind can come up with … The Strap can handle it
