This is a simple, rectangular finger ramp designed for humbucker-type pickups like those found on Stingray basses. Prices vary depending on the design, so please be sure to confirm the specifications ① to ③ below in the comments before purchasing. If you are unsure about the appropriate thickness for your instrument, we can offer suggestions if you contact us (^^) The basic design is flat, but depending on the string height, we may suggest a simple arched design even with specifications ① or ②. ① Flat top surface, specifying only thickness and length (width 90mm x length up to 70mm) ② Length of 70mm or more, or if changing the width (e.g., for 5-string models) ③ Custom-made with an arched top surface (freely specify width and length: full order) The prices are as follows: ①: ¥1100 ②: ¥1480 ③: ¥2840 If you want ①, please purchase it as is and let us know your desired thickness and length. For ②, please contact us to adjust the price before purchasing. For ③, we will ask about your string height and process it with a curved surface shape that matches your individual settings. If we determine that the height of the 4-string side end is too low and your thumb may not be able to rest on it, we may add a rest after consultation. If the fit is not right due to measurement errors, we offer a guarantee of a return + re-shipping fee + ¥300 for re-creation, so please feel free to use it. (We will exchange it free of charge if the incompatibility is due to our error) Regarding returns, you can simply drop it in the post using standard mail, which costs around ¥84-¥120.
