4-String JB Semi-Custom Finger Ramp - For All Jazz Basses

We design the length and thickness individually after confirming the size, so for 4-string JB type basses, including Fender, AtelierZ, History, Sadowsky, and others, we can deliver a compatible product in most cases (^^)

Although many manufacturers are not even aware of it, this part often becomes unusable if the thickness is not adjusted individually.

For 5-string basses or those with layouts significantly different from standard JB basses, separate arrangements will be made. If you are concerned, please contact us first with the model number (prices may also vary). This is because if the bass is equipped with a proprietary pickup, it may not fit our 4-string layout.


- Equipped with screw protection and can be easily attached with the included double-sided tape!
- The top surface shape can be flat or arched to match the string height (for semi-custom orders, we apply an appropriate arch from our standard molds).
- Depending on the design, a rest for placing your thumb may be added, as shown in the second image. (It is not added if it is deemed unnecessary. Please consult us in advance if you have any requests regarding the addition or omission of this feature.)
- We also offer adjustment guidance for those who are unsure about their instrument's setup.
(There are very few people, including instrument shops, who have proper knowledge of bass setup...!)
- We understand that measurements taken by customers themselves or differences in individual playing styles may lead to a less-than-perfect fit, so we offer exchanges for a fee of 300 yen, including round-trip shipping (^^)

We also offer slight discounts for bulk purchases, so please consider it.

We also accept custom orders for various shapes and string height tracking designs.
We propose designs tailored to your playing style, so please feel free to contact us.
