The Ibanez RG1550ML is a left-handed RG seriesPrestige electric guitar model issued in 2009. Like its right-handed counterpart, the RG1550M, it features a basswood body, a maple fingerboard, pickguard mount Ibanez made pickups and the Edge Pro tremolo. Unlike the RG1550M, it is only available in Black.
By late 2009 the RG1550M was discontinued and Ibanez started production on its replacement, the RG1550MZL featuring the Edge Zero tremolo. The USA Ibanez website however still only lists the RG1550ML as of 2010 & 2011.
