2. Setup
2.1 Unpacking
Carefully remove your Ibanez JEMJR electric guitar from its packaging. Ensure all included accessories, such as the guitar itself, are present. Inspect the guitar for any signs of damage that may have occurred during shipping.
2.2 Initial Tuning and Bridge Adjustment
The Ibanez JEMJR features a double-locking tremolo bridge system, designed for excellent tuning stability during aggressive playing and pitch bends.
- Unlock the Nut: Use the provided Allen key to loosen the three locking nuts at the headstock.
- Rough Tune: Tune each string to its desired pitch using the tuning pegs on the headstock.
- Lock the Nut: Once roughly tuned, tighten the locking nuts at the headstock. Do not overtighten.
- Fine Tune: Use the fine tuners located on the tremolo bridge to achieve precise tuning.
- Bridge Balance: Ensure the tremolo bridge is floating parallel to the guitar body. If it's tilted forward or backward, adjust the spring tension in the back cavity of the guitar. Refer to a detailed Floyd Rose-style tremolo setup guide for comprehensive instructions if you are unfamiliar with this process.
