Ibanez GSRM20 Mikro Short Scale Bass Guitar

Gearank Recommendation

The GSRM20 Mikro appeared on our recommended list for Bass Guitars Under $300 when we first published it in September 2016.

It remained on the recommended list until it was out-ranked by other models in May 2022.


Ibanez knows how to make instruments, including affordable bass guitars, play as fast and comfortably as possible. Case in point is the Ibanez GSRM20, which features Ibanez' smooth playability with its flat 12" fingerboard radius and low action setup.

Combined with its short scale configuration, lightweight body, and contoured edges, this super affordable bass is considered by many as one of the most playable basses in the entry level market, as reflected in reviews.

And it's not just playability because Ibanez did not skimp on the quality of the pickups and tonewoods, which are well appreciated by owners.

When we looked at user reviews we found the general sentiment is that this bass guitar has surprising quality for the price.

If you're looking for a cheap bass guitar that's easy to play, while still sounding good, then check out the Ibanez GSRM20.
