This is a speaker ring that fits into the speaker part of the ZO-3. Since parts supply from FERNANDES has ceased, we have created replacement speaker rings using a 3D printer. We believe the quality is high, as it was made with great care. The color is glossy black, the same as the genuine product, and it has the same solid strength as the genuine part. Apply double-sided tape to the outer circumference of the speaker ring and fit it into the speaker part. It can be attached to ZO-3 series guitars and fits ZO-3s with a speaker hole diameter of 95mm. We have done the following for its creation: - We measured the genuine replacement speaker rings sold by FERNANDES down to 0.01mm and created them with exactly the same dimensions. - We outputted with the highest precision using an ultra-small nozzle, resulting in a finish where unevenness and steps are completely unnoticeable. - We created over 20 prototypes and produced a satisfactory product that is comparable to the genuine replacement parts sold by FERNANDES. Notes: The ZO-3 has been sold for about 30 years, and there may be minor dimensional changes in the speaker rings, or expansion and contraction of the wood due to aging of the ZO-3 itself. When we attached this speaker ring to 10 ZO-3s, 8 fit perfectly. One had a larger gap and fit perfectly with extra double-sided tape. Another was a bit tight and required adjustment by lightly sanding the contact surface of the speaker ring with sandpaper. Therefore, although we have created the speaker ring with the exact same dimensions as the genuine product, it may not fit your ZO-3 perfectly. Please only purchase if you understand that you may need to make slight adjustments yourself. *This is not a genuine manufacturer product. *We will ship within 1-2 days of purchase, regardless of weekends or holidays. *We have multiple units available, so the photos are stock photos. *Please note that it cannot be used on ZO-3 models with a raised speaker section from the earliest models.
