Has anyone ever put some of these Mico Dots things in/on their bass? I've just odered some for some expensive camera gear that got stollen and eventually recovered and returned to me, minus the serial numbers now, but am getting enough that I'll have some spare. If anyone's used them, can you really not detect that they're there? Has anyone actually had something stollen and the dots made a difference? I like the idea of it, but if anyone's got any experience, I'd be keen to hear about it. Ryan.
