Yamamoto Sound Craft PB-21 African Ebony Spike Receiving Base

The sound of wood for musical instruments. Prevents metal resonance for a clear and tight sound

PB-20 and PB-21 are setting bases used to counter vibration in amplifiers and speakers. The material is African ebony, which is one of the hardest and strongest materials of all woods.

The good sound brought by rare musical instrument wood

• Highest level of hardness: African ebony wood is very hard and strong, making it one of the ideal materials for setting bases.
• Soundability: This rare material is actually used in woodwind instruments such as oboe and clarinet, and has a reputation for sounding good.

Concave shape and vibration damping effect

The PB-21 has a recessed shape and can be used as a receiving base under the pins of speakers or amplifiers with spike pins.

• Elimination of Metal Resonance: It prevents metal-specific resonant sounds that are usually common when metal spike pins are hit by metal plates, and you can get a pleasant and clear reproduction sound in your ears.
• Sound Tightening: The combination of PB-21 allows the metal spikes to bite into and stabilize it, resulting in a clear and tight sound.
