A Japanese Bossa five string bass in for a setup and a "finger ramp." Finger ramps are an additional piece of wood fit in between the pickups to allow the player to have a consistent anchor point for their thumb As you move towards the neck, the tone is fatter and playing towards the bridges yields a brighter attack. The ramp helps the player to have more consistency with the right hand technique.
This is an absolutely beautiful bass that I had not heard of before. Super versatile. Originally the player had it set up with higher action and a high C (tuned EADGC). We dropped the action down considerably and set it up with a low B (BEADG).
