Yamamoto Sound Craft PB-21& PB-20 Ebony Spike Base Set

Setting Base PB-20 and PB-21 are amplifiers and speaker setting bases that can be used alone or in combination with each other. The material is African Black Wood, one of the hardest and strongest materials of all woods. This material is now a rare material, but it is actually used in musical instruments such as oboe and clarinet, and has a reputation for its good sound.

Moderate spike bite gives you a clear and toned sound

The PB-20 is pin-shaped and can be placed under an amplifier or speaker as it is for point support. The PB-21 is also recessed and can be used as a receiving base under the pins of speakers or amplifiers with spiked pins. In addition, when the PB-20 and PB-21 are combined and used under an amplifier as a top and bottom structure, both the top and bottom are flattened, and the audio equipment can be supported by 3 or 4 points with good stability.

Normally, metal is often used for these pinpoint basses, but metal spikes often produce metal-specific resonant sounds, and by combining our hard wood such as PB-20 and PB-21, these resonant sounds can be prevented and a clear sound can be obtained in the ear. In particular, if you receive a metal spike pin with a metal plate, it is easy to get on the resonant sound, but by combining PB-21, the metal spike can bite into it moderately, stabilize it, and prevent metal resonance.
