Thank you for viewing. This is an Ibanez POWEROCKER Stratocaster-type bridge for sale. It allows for smoother arming compared to a standard synchronized tremolo. It also makes tuning more stable. While it's not a direct replacement, it can be installed on Stratocaster and Dinky-type guitars with minor modifications. This is highly recommended for those who dislike the bulky look of a Floyd Rose. It's in relatively good condition, but please understand that it is a used item. It may not be suitable for those who are overly concerned about minor details. Thank you very much!
