The GRGM21MSP is an RG series short-scale miKro solid body electric guitar. It was produced in China as part of the entry-level GIO line and was released as a limited edition model in the fall of 2012.
The GRGM21MSP is similar to the GRGM21M regular production model, but features a choice of two special finishes: Vivid Orange or Vivid Pink. In each case the head stock is painted to match the body. It has a downsized nato body bolted to a maple neck with a 22.2" scale 24-fret maple fingerboard with black dot position markers. Components include a pair of Ibanez humbucking pickups with black bobbins mounted in a black pickguard, a fixed bridge, and die-cast tuning machines.
