The root beer metallic Ibanez GIO Series GSRM20 miKro is a compact 4-string bass, ideal for younger players, players with back and neck problems, or anyone else that wants a smaller, lighter instrument that still packs a ton of low-end punch. Featuring a 28.6" scale maple neck and a jatoba fingerboard with white dot inlay, plus Dynamix P & J style pickups, this bass is easy to play with a big sound.
