The Ibanez SR400 bass guitar is very comfortable to play. The neck is thin up at the headstock, you can move your hand along it well because of the necks finish. The SR400's neck at the back has a matte finish making it very easy to slide your hands up and down the neck. Its easier to play the higher frets because the neck is a bolt-on with a curve where the neck bolts.

The body of the Ibanez SR400 is contoured very well. There are no sharp edges anywhere. You can play the SR400 standing up or sitting comfortably. If you are sitting down and put the bass on your right thigh, it will stay balanced and not lean one way or another.

The SR400 bass guitar is very playable because the strings are loose. You won't have to play with much force to get a sound, and it won't wear your fingers out so much.

The pickups of the SR400 Ibanez are in "P/J" configuration. There is a split "P" pickup at the neck position and a single humbrucker at the bridge. For each pickups volumn there are three knobs and one for tone.

The Ibanez SR400 bass guitar stays in tune very well. The tuners at the head are 2 on each side, and they are Gotoh tuners. The tuners are not to tight or loose, but they are light enough to keep the strings in tune.

The SR400 bass is good for an intermediate guitarist, and the best thing about it is its neck is so smooth, playable, and thin.
