The casino, which spent $500 million renovating the soon-to-be-opened facility, installed a 30-foot sign shaped like a Gibson Les Paul guitar on Thursday.
There was only one problem - the word "rhythm" was misspelled on the rhytm and treble switch as “rhythem” with an “e”.
The giant guitar is one of two being installed at the new resort. There’s no word yet on whether the second guitar is playing the same tune.
Hard Rock officials say the typo was corrected by removing the extra vinyl letter.
The Hard Rock Hotel & Casino will open 28 June, the same day as the Ocean Resort Casino.
