Ibanez GSRM20 Mikro Bass Review Overview

This is my Ibanez Mikro Bass review in a nutshell.

It’s an inexpensive bass, but this doesn’t mean that Ibanez skimps on quality.

  • The pickups are passive
  • The bass is lightweight
  • The controls are simple and easy to use
  • The short scale and compact body are comfortable and great for beginners or bass players with smaller hands

The hardware, such as the tuners and bridge, are nothing to write home about, but they get the job done!

There are occasional issues with frets, but that’s always a variable to consider with inexpensive bass guitars.

Lastly, the electronics setup is simple, and you’ll likely be able to get the tones you want from this bass if you have a decent bass amp or bass pedal setup.

Design and Features of the Ibanez Mikro GSRM20 Bass

For an always up-to-date description of the Ibanez Mikro GSRM20 Bass, look on Ibanez’s website.

Size and Build of the Ibanez Mikro GSRM20 Bass

This is an Ibanez Mikro model, which means that it has a smaller body compared to a regular bass guitar.

It’s a 3/4 size and has a scale length of 28.6 in, which isn’t too much smaller than your typical bass guitar.

And due to its short scale length and compact design, it’s pretty easy to play! 

Despite its low price tag, The Ibanez GSRM20 Mikro Bass is built with good quality materials, including a popular body and a maple neck. 

It’s also lightweight, coming in at only 6.9 lbs., which is great for us bass players who don’t want to be hauling around a tree stump in our gig bag.

Hardware and Controls of the Ibanez Mikro GSRM20 Bass

The Ibanez Mikro Bass features a p/j pickup configuration, with a Dynamix P pickup in the neck and a Dynamix J pickup in the bridge position. 

These are passive pickups, which means you don’t have to worry about hauling around and replacing batteries for your bass guitar all the time.

The controls are easy to use, consisting of two volume knobs, one Tone knob, and the three-way pickup selector switch.

As for the hardware, the tuning machines and B10 bridge get the job done. Sure, they’re nothing too fancy, but this is a budget Mikro Bass we’re talking about, not some high-end Stingray.

The strings are not the best out of the box, but you can change them if they bother you too much.

Sound Quality and Performance of the Ibanez Mikro GSRM20 Bass

This bass has a simple pickup configuration and sound setup but can sound like a beast with the right bass guitar rig.

Tone and Versatility of the Ibanez Mikro GSRM20 Bass

You know, the Ibanez Mikro GSRM20 has a great sound-to-price ratio. 

It’s quite versatile for how inexpensive it is. After all, the pickups on it are pretty good. With the right amplifier or pedalboard setup, you can get great tones out of this thing suited for various genres, including rock, pop, and funk.

And for a beginner bassist, a three-way switch with a simple volume and tone knob set-up is a good thing. There’s no need to complicate sound for a beginner.

This demo video from Patrick Hunter is one of the best Ibanez Mikro Bass review demos I’ve found. It really showcases the types of tones and sounds you can get from the GSRM20.

And I’ll always say this, the player and the EQ/Amplifier matter. Any good bassist with a good amp can make just about any bass guitar sound good!
