Finger ramp compatible with Yamaha BB series. It generally fits grades from BBP to BB734A and 234, as well as older models like 2025 to 5000 and V, but this has not been fully confirmed. Available for both 4-string and 5-string basses (please provide your model number after purchase as the sizes differ). Choose from the following two specifications: ① 1680 yen ② 2480 yen (free modification/exchange) ① Flat top surface with adjustable thickness only (rounded edges and bevel cuts on both sides, etc.). Simple arched top may be used if necessary. ② Custom arched top that adjusts to string height changes (accommodates individual settings). Specification ② is generally more suitable for BB basses, but recently, more people are opting for ①, so we are offering them separately. We basically accommodate all cases, including special asymmetrical designs. We offer custom-made designs tailored to the height settings of each string on your instrument, providing a user-friendly tool even for those without prior experience using finger ramps. If you are unsure which option to choose, we can help you decide based on your individual settings (^^) The corners and edges are beveled or oval-shaped, providing a very smooth and comfortable feel. Additionally, specification ② features a seamless finger rest on the 4-string side, enhancing usability for both fingerstyle and pick playing (the block may be omitted depending on the design thickness). We also sell dedicated neck-end slopes (custom-made adjustment: 2480 yen each). Discounts are available for set purchases, so please consider them (^^) As shown in the third photo, we have transitioned to the Ver7 type as the basic specification from December 2024. Please consult us in advance if you wish to purchase the old Ver5 specification. (Ver6 type is completely discontinued and not supported)
