They were an almost perfect fit. The sleeves fit fine in the headstock, but screw holes had to be drilled on the backside. Not a huge problem though. I otherwise love the look, and the function is smooth. A good value for the money. Review: Perfectly adequate - but be sure to grease them - These are perfectly good tuners. I put them on an Ibanez TMB100 to replace two broken tuners. The holes lined up, not perfectly, but well enough so I didn't need to drill. As far as I can tell the quality appears to be the same as the original. They hold in tune just fine. Note, the gears were bone dry as arrived, so you absolutely MUST grease them or else the teeth will break! I use a tube of white lithium grease. Before putting strings on, add the grease where the sprocket meets the roller and turn the tuners until the grease moves all around the roller. Keep turning until you get a nice smooth action. Only then can you put the strings on. ## Features - Heavy duty internal gear, economy sealed bass tuning keys set for Precision Bass or Jazz Bass. - Fits for 15mm peg hole, the bushing inner diameter 18mm, outside diameter 21mm, peg length is 30mm. for specific dimensions, please look at the size diagram. - Zinc alloy material, Gear Ratio: 1:22; Color: Black. - Includes 4pcs open frame right bass tuners. Mounting screws, ferrules and threaded bushings are included. - Great replacement for the old, broken tuning pegs. Essential accessory of a bass, perfect for you! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07LBDF4S5 | | Back Material Type | Basswood | | Best Sellers Rank | #19,609 in Musical Instruments ( See Top 100 in Musical Instruments ) #14 in Bass Guitar Tuning Keys | | Body Material | Metal | | Body Material Type | Metal | | Brand | Metallor | | Brand Name | Metallor | | Color | 4R-Black | | Customer Reviews | 4.2 out of 5 stars 395 Reviews | | Fretboard Material Type | Basswood | | Guitar Bridge System | Fixed | | Guitar Pickup Configuration | S | | Hand Orientation | Right | | Included Components | 4 bass tuning pegs, 4 ferrules, 16 mounting screws | | Instrument | bass guitar | | Instrument Size | 15mm | | Item Dimensions | 3.35 x 1.77 x 1.57 inches | | Manufacturer | Sunsmile | | Manufacturer Part Number | MHB 01-BK | | Material Type | Metal | | Model Name | Bass Tuning Machine | | Model Number | MHB 01-BK | | Neck Material Type | Basswood | | Number of Items | 4 | | Number of Strings | 4 | | String Material Type | Metal | | Top Material Type | Basswood | | Unit Count | 4 Count | | Warranty Description | 1 year manufacturer. | ## Product Details - **Back Material Type:** Basswood - **Body Material:** Metal - **Brand:** Metallor - **Color:** 4R-Black - **Fretboard Material Type:** Basswood - **Guitar Pickup Configuration:** S - **Hand Orientation:** Right - **Neck Material Type:** Basswood - **String Material Type:** Metal - **Top Material Type:** Basswood ## Images ![Bass Guitar String Tuning Pegs Machine Heads Tuners Tuning Keys - Image 1](https://m.media-amazon.com/images/I/6171HicqhsL.jpg) ![Bass Guitar String Tuning Pegs Machine Heads Tuners Tuning Keys - Image 2](https://m.media-amazon.com/images/I/61wmztYdsrL.jpg) ![Bass Guitar String Tuning Pegs Machine Heads Tuners Tuning Keys - Image 3](https://m.media-amazon.com/images/I/61ygWgMT+1L.jpg) ![Bass Guitar String Tuning Pegs Machine Heads Tuners Tuning Keys - Image 4](https://m.media-amazon.com/images/I/61XhwJ04IKL.jpg) ![Bass Guitar String Tuning Pegs Machine Heads Tuners Tuning Keys - Image 5](https://m.media-amazon.com/images/I/61JUYgyW3sL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: What are the mounting hole center to center dims. (in all planes) , as well as post diameter. please provide. thanx gb** A: I believe that mounting hole center to center is going to depend on your nut width and consequently string spacing, as well as on your headstock shape and offset, so no one answer fits all. The other dimensions are given in the product information views. **Q: Can you please add detailed dimensional drawing?** A: Have added, please see images. **Q: Will these fit an American jazz bass?** A: Yes, these fit. **Q: Where is this manufactured?** A: This is made in china by Sunsmile. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good, solid hardware for the price. *by R***S on August 16, 2020* I used these to restore an old Indonesian P Bass to working order.
