TOMENGBEI gg AV Toolbox AP-411 Lip Sync Corrector, Up to 300ms Delay, Stereo RCA Connectors

This is exactly what I've been looking for to help sync up Guitar Hero to work with modern flat screen TVs. Before, the games were not playable. But thanks to this device I can now shred like a pro!

Works as advertized. Got my audio almost in sync. Would have been better if it was continuously variable. But This is a neat device and improved my system, at full delay!
