The instrument can be a little small for some amps. The manual you will get with the instrument is useful but you may notice that it has some mistakes and could also have missing information.

However, this is not a big issue as the guitar is okay on the overall. For an instrument of this price, it does most of the stuff that is expected of it.


We looked through the market to see if there were other products we could compare the Ibanez GSRM20 Mikro to and found the Dean HILLSBOROJRCBK Hillsboro Junior 3/4- 4-Strings Bass Guitar. The Darn Hillsboro Junior is much cheaper.

It is also the bass guitar that will work for someone looking for an instrument to be used by children. Just like the Ibanez GSRM20 Mikro, it is suitable for someone with smaller fingers and hands or a guitarist who wants to occasionally switch to bass.

At 30″, the scale is much smaller when compared to the 34″ or 35″ you will find n standard electric bases. This may compromise the tone.

Another product you can look at is the Dean E09M Edge Mahogany Electric Bass Guitar. Compared to the Ibanez GSRM20 Mikro, this bass guitar will cost you more but it still remains in the affordable range. Its body is contoured so that you have increased comfort when you are playing the instrument.

Like the Ibanez GSRM20 Mikro, the pickup on the Dean E09M Edge is also passive. If you enjoy all things vintage, you will love the way this guitar looks. It features basswood construction while the top layer is made from mahogany. It has a way of letting those who see you using it know that you are sophisticated.


On the overall, we can easily recommend the Ibanez GSRM20 Mikro Short-Scale Bass Guitar. It will especially be appreciate by someone looking for an instrument that is not too bulky and can easily be used by someone who travels a lot.

It will also work well if you want to use it for training children how to use a bass guitar. Adults will small hands or the elderly will also find it useful as it is lightweight and easy to play.

As long as you remember that this is an affordable entry level product, you will realize that it is good value for money. Like all products in this price range, it does have its own issues like height screws that tend to misalign and some adjustment screws that can become cranky over time.

The bridge pickup can become noisy at times. We don’t think that these are deal breakers. On the overall, we think that the flexibility you get in terms of tone on this instrument is superior to others in the same class.

If you are a new player, go for it. If you have been doing this type of thing for something and need something different, you can also try this one.
