The GRGM21CT1 is an RG series short-scale miKro solid body electric guitar model offered by Ibanez. It was made in China as part of the entry-level GIO line and was introduced as part of a limited edition series for Summer/Fall 2014.
The GRGM21CT1 is similar to the GRGM21 regular production model, but features a special red finish (including the headstock) with yellow pickguard and orange pickups and toggle switch. Other than the original color scheme it shares the same specs as the GRGM21.
Another special edition GRGM21, the blue and pink GRGM21CT2 was issued concurrently.
