Yamamoto Sound Craft PB-9 African ebony pin-shaped base

Setting Base PB-9, PB-10 is a setting base for amplifiers and speakers used alone or in combination with each other. The material uses one of the hardest and strongest materials of any wood, African Black Wood. This material has become a rare material now, but it is actually used in the oboe and clarinet of the instrument, and has a reputation for its good sound.

The PB-9 is pin-shaped and can be placed under the amplifier or speaker as it is and made point support. In addition, the PB-10 is concave and can be used as a receiving base under a speaker with a spike pin or an amplifier pin. In addition, PB-9 and PB-10 combine each and use under the amplifier as an upper and lower structure, both the upper and lower surfaces will be flat and stability can be supported by 3 or 4 points.

Metal is often used in these pinpoint bases, but metal spikes often produce resonant sounds unique to metal, and by combining hard wood such as PB-9 and PB-10, they can prevent resonant sounds and obtain comfortable, clear playback sounds in the ears.
