Guyker GG901S Fine-Tuning Tremolo Bridge for Headless & Electric Guitar
SKU:GG901S-BK
PRODUCT DESCRIPTION
Built for flexible tremolo setups on headless and standard electric guitars. This fine-tuning tremolo bridge includes a height-adjustable locking nut block for headless guitar projects, while the bridge can also be used as a regular tremolo bridge when the locking nut block is not installed.
Key Features
- Dual-use tremolo bridge design: Suitable for headless guitar builds when used with the included locking nut block, or for standard electric guitar tremolo setups without the block.
- Height-adjustable locking nut block: The included locking nut block helps secure the strings for headless guitar applications and allows height adjustment during setup.
- Fine-tuning control: Six rear fine-tuning knobs allow convenient string tension adjustment after installation.
- Adjustable saddles for intonation: The saddles can be moved forward or backward, and the rear screws allow intonation adjustment for each string.
- Solid hardware construction: Brass saddles, a brass tremolo block, a stainless steel base plate, and a stainless steel tremolo arm provide a reliable platform for replacement and custom build projects.
- Fitment reminder: Please compare the string spacing, mounting spacing, tremolo cavity depth, bridge dimensions, and block clearance with your guitar before ordering.
