The Mikro GIO: The Ibanez Spirit in a Compact Format

The GSRM20-BK is part of the GIO series, designed to offer the Ibanez DNA in an accessible and practical approach. In the Mikro version, it focuses on ergonomics and ease of play, without sacrificing the essentials: reliable craftsmanship, simple and effective electronics, and a bass capable of covering many contexts.

Who Is It For, and What Styles?

This bass is especially aimed at beginners, guitarists wanting to switch to bass, or musicians looking for a compact bass for home, rehearsals, or certain travels. Thanks to its PJ configuration, it suits rock, pop, funk (with a more biting attack on the J pickup side), and anything that requires a solid and versatile foundation.

The Sound

The poplar body promotes a balanced output, with present mids and a consistent response, useful for remaining clear in a mix. The Dynamix P pickup in the neck position delivers a full low end and warm low-mids, perfect for laying down a line. The Dynamix J at the bridge adds definition and bite, ideal for gaining precision, attack, and articulation. Combining both yields a versatile tonal palette, suitable for most situations.
