The GDTM21 is a compact Destroyer-styled solid body electric guitar introduced by Ibanez in 2011. It is part of the miKro series of short-scale guitars and was made in China as part of the entry level GIO line.
The GDTM21 was available only in 2011. Along with the GICM21 (released at the same time), it was the first non-RG-style body in the Mikro series line. The GDTM21 was sold only in Candy Apple Red with gold hardware and white pickups.
The GDTM21 is similar to the GRGM21, in terms of specs, with the major difference between the two models being the shape of the body.
