Thundergod Posted March 23, 2009 Share Posted March 23, 2009 Are you talking about those covers that used to come "on top" of the back of the pots? Link to comment Share on other sites More sharing options...
daveinspain Posted March 23, 2009 Share Posted March 23, 2009 What is the funtion of this cover inside the guitar and if removed will it increase feedback noise? I always wondered why they did that too... It was only done for a short time. Link to comment Share on other sites More sharing options...
slab man Posted March 23, 2009 Author Share Posted March 23, 2009 Yes , a cover over the pots. About 3 by 3 in. inside the cavity of the guitar. I guess it had something to with sheilding. Link to comment Share on other sites More sharing options...
elantric Posted March 23, 2009 Share Posted March 23, 2009 Yes - its Earth Shielding metal cover , used 1972-1983 and I wish they still employed it. or better still - use conductive paint in the control cavity and tie it to earth ground - like everyone else these days The shielding prevents RF noise and helps with those situations where you get tremedous "buzz" when you are not touching the strings. This type buzz is actually unique per individual and location. Basically the human body is 60% water - which is an electrical conductor. Your body resonates with any stray EMI fields in the area - from nearby AC power lines, or Cell phones or RF noise. You hold the guitar in close proximity, but if you do not touch the strings your "ungrounded" body radiates hum into any unshielded electronics - like the hot lugs on the volume pot , so you complain of "noise and hum and buzzes " when you let go of the strings. Most electric guitars have grounded strings - to provide a path to electrically ground the player , and minimize the human body EMI hum source. A guitar with fully shielded electronics is a joy to play - because when you let go of the stings - no hum kicks in. It allows you to play harmonics, let go of the strings and wiggle the neck at high volume - with no hum anomalies. These guitars are rare - and it means leaving the P.A.F metal pickup covers on. I recommend leave the metal cover on your Les paul in place, let it do its job it was designed to do. Link to comment Share on other sites More sharing options...
