Re: RG 550 / Lo-TRS - which spare parts fit?
I thought this as well, only OE and Lo-pro edge on the 550. Today i came across a 550(according to the seller) but it had Lo-TRS stamped on the trem. My conclusion is that(without pictures-so i could be wrong) a "RG550" looking guitar with Lo-TRS trem would be an Ibanez RG450 mij. But pictures of the acctual guitar would be a big help.
Think that the pickguard on the 450 makes people think it's a 550.
