Miyako Woodcraft - High-Quality San-gen Bridge Prototype

Looking at the craftsmanship of the legs and the part where the strings rest, you can see it's meticulously made, making the difference from other manufacturers clear. The design differs from current products, suggesting it was either sold in very limited quantities in person a while ago or is a prototype.

Height: 11mm, String spacing: Approx. 10mm

The material is likely mammoth ivory, but given that the design predates Miyako Mokugei's period of obtaining licenses and selling, it might be a higher-grade material.

You won't be able to get this again, so please consider it favorably.

Mammoth ivory bridges are also popular items and are always sold out online, so don't miss this chance!
I felt there was almost no difference in sound compared to current products.

Reference from Miyako Mokugei's website.

Compared to a standard bamboo bridge, the sharp edges in the high-frequency tones are softened, resulting in a very mellow overall sound. The mid-to-low frequencies gain more presence, with a deep, warm tone and a well-extended sustain.

When attached to a sanshin with artificial skin or reinforced skin (double-layered), it reduces the artificial kink and jiri-jiri noises, transforming the sound into a soft tone reminiscent of natural skin. The sustain of this soft tone then extends for a long time.

However, it is not well-suited for sanshin with naturally loose skin or single-layered natural skin tuned to 50-70% tension. The mid-to-low frequencies can become overly emphasized, resulting in a very peculiar sound.

Typically, commercially available bridges have two legs, but this one features a [four-leg] design, allowing it to be placed regardless of the front or back, and most importantly, offering excellent stability.

Note: Those seeking shop-level quality or who are sensitive should refrain from purchasing.
