Description

The Ibanez GSRM20 is the compact dynamo of the bass guitar world, crafted especially for those who desire a smaller, more manageable instrument without compromising on sound. Perfectly suited for tight spaces such as tour buses or cozy home studios, this 3/4-size bass guitar promises to deliver the same powerful sound of its full-sized counterparts. Its short 28.6" scale length makes it an excellent choice for players with smaller hands, young rockers, or anyone who appreciates the agility of a lighter instrument.

Built with a poplar body and a sleek maple neck, the GSRM20 is as durable as it is playable. The jatoba fretboard offers a smooth playing experience, while the medium frets add to the comfort and precision of your performance. Featuring both Dynamix P and J pickups, this bass gives you access to a wide range of tones, from the punchy lows of a P-style to the articulate highs of a J-style, making it a versatile choice for any musical style.

With chrome hardware and a B10 bridge that ensures impressive sustain, the Ibanez GSRM20 is the perfect partner for your musical journey, whether you're a budding bassist or a seasoned pro looking for a reliable travel companion.

Key Features:

  • Compact 3/4-size body made from poplar
  • Maple neck and jatoba fretboard with medium frets
  • 28.6" short-scale length for enhanced playability
  • Equipped with Dynamix P and J pickups for versatile tones
  • B10 bridge for improved sustain
  • Chrome hardware for a sleek, polished look

great bass.

the Ibanez micro bass is an amazing bass with those of shorter stature. used by Aaron Davis, or more commonly known as Neon tiles, this bass is an amazing instrument for any genre.

It's a stick

If my style could be explained in colloquial terms, stoner/doom/metal/sludge. You don't need a fancy stick for that. Beat the strings and sound happens.
