Independent shopping perspective
The Korena take
These chrome Badass TK-7818 SGT machines are a 2+2 replacement option for Ibanez, Schecter, and other contemporary basses. The high-tolerance machined brass gear uses a 20:1 ratio to support accurate tuning with minimal slip. Steel worm gears and sealed housings are specified for durability, while the zinc housings are kept lightweight so the replacement set does not add unnecessary weight at the headstock.
Strong match
Who this is for
- Replacing tuners on an Ibanez, Schecter, or similar contemporary bass with a 2+2 headstock layout.
Consider the trade-offs
When to look elsewhere
