Bought this to replace springs on my Original Floyd Rose setup. Unfortunately I did my installation after the money back period has been exceeded, otherwise I'd return this to the store. Springs made my Floyd Rose getting out of tune equally on all strings after a bar move (going cents down after a bar push, and cents up after a pull). Probably I was just unlucky of course, but for me this product can't compare to any quality springs of Schaller or Floyd Rose Original. Tremolo got back to normal only after I removed the Göldo springs and installed original springs from Floyd Rose.
