Disclaimer: I am not a bass player. I'm sure a real bass player could and would find faults that I don't but here's my guitar-playing Dad's-eye-view of the thing.
I got an Ibanez miKro bass for my 10 year old last Christmas. He couldn't live without a non-stock color, Starlight Blue. One call to Chris Jenkins @ Sweetwater was all it took to get a Starlight Blue model ordered fresh from the factory. Chris even helped find a suitable gig bag and, as an added bonus, managed to get the thing delivered in time for Christmas. So, yeah, Sweetwater kind of rocks...but you knew that.
The bass itself was a steal. I've played cheaper guitars and there's almost always something missing in quality, tone, and/or playability. Finding no fault in it myself, I handed it off to my brother who has played bass for 25+ years for a demo. Playing through a vintage SWR head & 118 cab, the thing rocked. Even on the shorter strings, it got seismic. It sounds good in standard tuning, the pups and controls give a very wide range of timbre. It is completely playable, per the player. The fit and finish are good. It's holding tune. No complaints in design or build. It's legit.
My 10-year-old is right on the verge of outgrowing his 3/4 guitar and this short-scale bass works for him. At this price, it was a great way to give him the opportunity to explore playing bass without breaking the bank. It works in grown-up hands, too, so I don't think outgrowing it will be a huge concern. At 28.6" The scale is closer to an average full-size guitar than to an average bass so going back and forth with guitar is not that disorienting.
Ibanez has really managed to strike a nice balance between price and quality here. I'm very happy with the purchase and, as always, I'm very happy with the Sweetwater buying experience. Thanks, Chris!
