Guyker ATR7232 Acoustic Guitar Bone Saddle, Red, Pre-Slotted, 72x3x12mm

Made from cattle bone and supplied as a two-piece set, the Guyker ATR7232 is a red, pre-slotted replacement saddle for acoustic guitar. Its listed size is 72x3x12mm, so the dimensions are central to deciding whether it suits your instrument—not just a finishing detail.

The grooves are already cut to locate the strings, which may make installation more straightforward, but the saddle still needs to match the original part and be set up correctly. The listing does not identify a specific guitar model that it fits.

Technical overview

• Type: Acoustic guitar bone bridge saddle
• Format: Pre-slotted, 6-string
• Size: 72x3x12mm
• Material: Cattle bone
• Color: Red
• What’s included: 2 lower string bone nuts

The product is presented as a bone alternative to plastic saddles, with the manufacturer describing a brighter, resonant sound and improved sustain. Those are intended benefits, not a guaranteed change: the result can depend on the guitar and its setup. The pre-cut string locations are useful if you want a replacement with grooves already formed rather than a plain piece that requires slotting.

Everyday use

This set is intended for replacing the lower string saddle on an acoustic guitar. In a practical repair scenario, you would compare the listed dimensions with the part being replaced, then check that the strings sit in the slots as intended after installation. The manufacturer also positions it as a way to address fret buzz, but a saddle alone cannot be assumed to resolve every buzz, the cause and setup matter.

What does pre-slotting change for a replacement? It gives you defined string positions to work with, which can reduce the amount of shaping needed compared with an unslotted blank. It does not establish that the saddle will drop into every bridge without adjustment. If your current part has different dimensions or string spacing, this listing provides no compatibility confirmation for that guitar.

Included in the package

The package is listed as two lower string bone nuts. That gives you a second piece alongside the one used for a replacement, though the listing does not specify whether the pieces are intended as identical spares or for separate instruments. The product details also note that measurements are manual and may vary by 1–2mm, so the listed dimensions should be treated with that stated variation in mind.

Should you buy it?

Worth considering if you need a pre-slotted bone replacement for an acoustic guitar and the 72x3x12mm size matches the part you are replacing. It offers a different material and format from a plain plastic or unslotted replacement, while keeping the purchase focused on the saddle rather than a broader repair kit.

It’s not for you if you need a confirmed fit for a particular guitar and cannot verify the dimensions or string-slot arrangement against its existing saddle. The product information does not name compatible guitar models or provide slot spacing measurements. Choose it when those details line up with your instrument, otherwise, a replacement with confirmed measurements for your guitar is the safer route.
