Hey guys, I've been looking for ages, and I've been able to find the wireless systems, but is there a device where I can simply plug one 1/4" adaptor into my bass, and one into my amp like 2 USBs and have it work like a regular patch cable without the cord? I was at a concert the other night, and I could have sworn I saw one of the guitarists using a device that looked like someone had taken a headphone to 1/4" adaptor and plugged it into the guitar, and that's it, no extra thing on his belt or anything, and I immediately wanted one. I've heard mixed stories on quality, but generally the consensus seems to be positive. Any help would be amazing!
