Ibanez GSRM20B-WK Weathered Black Mikro Gio

A Mikro GIO Designed for Comfort Without Sacrificing Efficiency

This Ibanez GSRM20B-WK fits the GIO spirit: offering a reliable, accessible, and ready-to-play instrument. Its "Mikro" short scale format focuses primarily on ergonomics, with an easy-to-master neck and a compact body. It is an excellent entry point into the Ibanez universe for those seeking a practical everyday bass guitar, while maintaining true sonic versatility thanks to the P/J combination.

Who Is This Short Scale Bass For?

Thanks to its short scale and comfortable neck, this bass is particularly suitable for beginners, guitarists switching to bass, and musicians looking for a compact instrument (small hands, young bassists, transport constraints). In terms of styles, the P/J configuration and passive electronics easily cover pop, rock, punk, light funk, and any genre requiring a direct, clear sound that sits well in a mix.

The Sound

The Dynamix P (neck) and Dynamix J (bridge) pickup duo offers a very useful spectrum: the neck pickup provides body and round lows, while the bridge pickup adds definition and bite to better stand out in the attack. The 2 volume controls allow continuous blending of the two pickups, and the tone control softens the high end for more vintage sounds. The okoumé body promotes a balanced response and good presence in the low mids, and the maple neck contributes to clarity and precision. The purpleheart fingerboard with a comfortable radius helps maintain a stable feel, ideal for working on right-hand consistency and intonation.

Recommended Compatible Accessories

To protect and transport the instrument, the recommended IBBMIKRO gig bag is the safest choice. A standard strap and a chromatic tuner perfectly complete a rehearsal setup. A hex key is included for common adjustments.
