Description

Don’t be fooled into thinking the Ibanez GSR Micro is a toy. It’s made to the same high standards of the other GIO series guitars. The GSRM20B features, small scale SR body, full sound pickups, the same construction, same materials, and same set-up and inspection as its full size counterparts. Its shorter 28. 6” scale makes it perfect for tour buses, space-restricted home studios, folks with smaller hands, as well as young rockers or beginners.

    • Great fit for smaller hands
Color: Walnut Flat Style: 4-String
Great Bass for a decent sound. A little time setting nut height, neck relief and pick up heights and it was off to the races!! Smaller handed adult, easy to play and comfortable as it weighs less than a full size bass. So far so good, more than worth the price in my opinion

    • Impressed by this little monster
Color: Starlight Blue Style: 4-String
I chose this bass because I am used to playing guitar and wanted something to do some home recording with, and didn't want anything too big or unwieldy, and I am shocked by how small and light it is. It's smaller than the PRS guitar I usually play, but still sounds great. Pickups are passive but that's fine with me as active pickups are just another thing that can fizzle out at the worst possible moment anyway. My only real complaint was how incredibly out of tune it was on arrival, but any new guitar is going to need tuning and the stock strings should probably be replaced ASAP anyway. Would be a great starter bass and I wouldn't hesitate to gig with this if I had to. It looks cool too. ... show more

    • Great Bass for the player with normal hands!
Color: Walnut Flat Style: 4-String
Review Image by Casey Digital Design Inc.
After tuning it, I tried it out. It's great having a smaller bass with great sound like this Ibanez! It looks great, sounds good, and is responsive. One of the best things is that it's on the smaller side, enough that those of us who aren't wide receivers or have long fingers can easily play it! I'm thrilled I spent a little more to get an Ibanez over the lower-priced basses. The price is still very reasonable, and Ibanez has an excellent reputation for quality instruments. ... show more

    • This bass is an EXCELLENT value! After 50 years of playing bass!
Color: Brown Sunburst Style: 4-String
Review Image by John R. Kathrein
Out of the box, this bass is an EXCELLENT value! After 50 years of playing bass, I switched to Short Scale and will never go back to a 34" scale bass. Playing Short Scale is so much fun, I feel like I am cheating! I purchase this Ibanez Mikro as a backup bass to my Gretsch semi-acoustic short scale bass.I own a very high end Ibanez 34" scale bass and thought that the Mikro could not possibly have same quality. I was VRY surprise! I bought the Sun Burst finish and it looks really good. The overall fit and finish is excellent. The electronics sound great. It feels incredibly natural while playing. I gave the this review 4 stars instead of 5 stars for two reasons: 1) The strings that come on the bass are round wound, sound very metallic, sound very scratchy, and buzz a lot. I thought I would have to do a set up. I started out by replacing the strings with a set of DR Hi-Beam Flat Wound SS strings (ASIN B00O48Z5FE). They appear to be heavier that the OEM strings. All problems solved! 2) The only way to switch between the pickup (which sound very cool) is to roll back one pickup volume and roll up the other. I'm going to install a micro 3-way switch. Not a big deal for me, but I think should have been included in the design. Still for what the bass cost, most players can deal with turning the volume knobs. After all, how often does a player really do that? The Ibanez Mikro Short Scale Bass is a excellent instrument for new players and old players. I highly recommend it! Update: I installed a Switchcraft 3-Way switch. See the photo. Now, this is a 5 Star bass! ... show more

    • The Guitar Player's Perfect Guilty Pleasure Short Scale Bass!
Color: Weathered Black Style: 4-String
Review Image by rgordon
Just my opinion, but this just might be the guitar player's perfect guilty pleasure short scale bass! With its remarkably short 28" scale, it's so comfortable, balanced, light & easy to play! Amazingly inexpensive. Flawless fit & finish (at least mine was right out of the box - and in a really gorgeous matte slightly textured weathered black finish w/all black hardware). Just one minor out of the box issue - slight buzzing, but only on the E string and only when fretting the E on the first fret. So, possibly the second fret needed/needs minor dressing - but that was more than I wanted to attempt, so instead I simply raised the E string a hair at the bridge and the buzz was instantly gone, with no effect on E string volume that I could detect. The pickups sound fine to me. A true little gem at a truly bargain price. (Note - the gig bag was not included - it was a separate purchase - but for the price what can you expect?!) ... show more

    • A Bass Guitar, that's made for Guitar Players!
Color: Starlight Blue Style: 4-String
I've been playing guitars for over 30 years and on many guitars. I messed around with a Squire bass guitar many years ago, but it was huge and heavy, traded it in. I have 4 Ibanez guitars and was intrigued by the Ibanez Micro Short Scale Bass. It's the size of a guitar, weighs around 6 1/2 pounds and sounds amazing, easy to play and a lot of fun. Definitely can be used on Stage, tuning keys are ok, pick-ups, ok too. Someday I'll upgrade the pickups and tuning keys, but not a rush, this Bass is plain fun to play! ... show more
