Sorry, I really do hate to be negative but here we go.
I bought this as a replacement for my Les Paul bridge which has it's gold plating over the years due to sweat, general use etc. making the guitar look a bit dog eared.
I understood that this is not a genuine Gibson part but was willing to give it a go for the price - even if it only looked good for a few months or so.
1 gig! Just 1 gig and the gold has gone completely from the top edge where my wrist sometimes rests (palm muting etc).
Take my advice - avoid this product if you want your guitar looking good - the finish not fit for purpose.
The mechanics and functionality are fine, but so is my original bridge.
I'm remimded of a plaque on my Boss' desk which reads
"The bitterness of poor quality remains long after the sweetness of low price is forgotten".
Nuff said.
