The RG1550M is the successor of the 2003–2004 RG1550 model and is the first model offered after a five year gap that is a direct descendant of the iconic RG550. It was introduced at the 2009 Winter NAMM show.
The RG1550M features a basswood body bolted to a maple and walnut neck with a 24-fret maple fingerboard with small black dot position markers. Components include Ibanez pickups mounted in a black pickguard with V7 & V8 humbuckers flanking an S1 single-coil, an Edge Pro double locking tremolo bridge and Gotoh tuning machines.
The RG1550ML is a left-handed version. The RG1520A is a related model without the pickguard and the middle pickup which was offered with the same finishes.
Production of the RG1550M was ended in 2009 in favor of the new RG1550MZ introduced for 2010 which featured the Edge Zero tremolo. In the USA however, both of these models were listed as simply the RG1550M.
