Production Manager

​Tomohiro Shioiri


Material management starting with seasoning, we repeatedly devote a lot of time to dozens of steps while repeatedly deviating.

We make it with all our heart.

We were able to complete the Shior along with the specialists in each field.

We are convinced we can send out into the world the tools which enable the players to play comfortably, pleasantly and smoothly in various situations; live, recording and many other scenes.

We believe it will make the plyers thrilled and excited.

Support the rhythm, the song, the keyboard and the guitar inself.

From the viewpoint of a bassist, slightly of a guitarist and of a recording engineer, I consider the tone of the bace.

It is the tone I would like Japanese bassists to try out.

Please come and fly yourself into the world.

Please play the instrument powerflly.
The tone is really well-balanced, preparing countermeasure against noise and very low phase shift.

Carefully selected wood and electronic parts, hight quolity neck chosen all over the world.

This is the sound of Shior.
