I've been installing GT's Ghost stuff for years. Something has come tony attention. I just installed the AcoustiPhonic system for a fellow forumite. We verified that everything worked, but didn't have time to do thorough testing. When my customer got home he tried it out on his rig with some of his presets. He noticed a white noise type hissing on high gain presets even with the volume is down. I then checked my own guitar that has this installed and show nuff... Turned down my gate and HISS city.
So, can I get some ghost users to try this out with no gate on. Also, I need to know how long you've had this installed so I can try to pinpoint when this has changed. The preamp from my guitar was actually just installed as a replacement to a defective unit I swapped out for an out of state customer.
