Love this little short scale 5

I have owned this bas for about a year and I absolutely love it. Over the years I have possessed musicman, fender, gibson, ken smith, and higher end ibanez's. I can honestly say this little guy really holds it's own. It arrived perfectly set up, with nice low action, right out of the box. Basically plays and sounds like every Ibanez bass I've ever owned, which is great, especially at this price point. It's well balanced and feels like a real instrument, not a child's toy, which is something I was worried about. It's about the size of a strat! But lighter!! I dig the tone and so do friends and band mates. Fit and finish is really good. Fret ends are a little sharp. Pearl white finish is great. Neck has no finish at all. Just raw wood. Guess that's a way to save some money, but personally I love the unfinished neck. Negatives? Hard to complain at this price point. Tuners don't hold as well as a high end bass. To be expected. The fret ends are sharp and unfinished. That's about it. Bottom line: I love it. I have many basses, but end up playing this one all the time. Also being such a short scale, it's just easier to play.

Addictive Tone and Feel!

This is my first 5-string and I love to play this through the bass rig at church. Huge tone and this thing feels amazing to play. Full size basses are a challenge for my smaller hands but i can play so comfortably with this. I'm totally sold on 5-strings with the low B and rarely pick up my 4 string short-scale Ibanez. The pickups are much better than the ones in the 4-string. Would like to see more color options though(especially pearlescent white)

Small, lightweight, BIG SOUND

This little bass has got it all together. Just what I needed. It's light and very easy to play with a great big full sized sound. The intonation needed a little more setup but that was an easy fix. I love it.

Awesome tiny bass

Really good bass, my first 5 string and I like the fact it is short scale but is a proper instrument. Two pickups are nice to have also. Plays really well - expected from Ibanez. rotary knobs are cheap plastic but everything works well. Didn't get a bag with it which I forgot to check - I thought they shipped with one. Sweetwater packaged it well and it arrived in perfect condition.
