Overview
Carrying a short-scale bass onto a tour bus or into a small home studio is the use case for this Ibanez MiKro, a small-body SR design. Full-sounding pickups and the same construction as its full-size counterparts are part of the pitch.
A shorter scale suits smaller hands, young rockers and beginners, and still gives a fifth string. The body wood is listed two ways, the listing contradicts itself on the wood, and no case or strap is mentioned.
Who it's for
Players with smaller hands, limited space or a need to travel light can use the compact scale. Anyone who needs full-scale string tension or the exact body wood confirmed should look elsewhere.
Pros and cons
- Short-scale compact body
- Same construction as full-size Gio
- Body wood listed two ways
- Case not included
- Short scale changes string feel
Performance notes
A shorter scale reduces the reach along the neck and lowers string tension compared with a full-size bass, which suits smaller hands. Magnetic pickups feed a jack for connection to an amp, and the fixed bridge anchors the strings at a set point.
