Floyd Rose FRTPS4000 1000 Series Pro Tremolo System 7-String Nickel – Advanced Tremolo Performance

The Floyd Rose FRTPS4000 1000 Series Pro Tremolo System 7-String Nickel is built for guitarists who demand rock-solid tuning and expressive playability on 7-string electric guitars. This double-locking, low-profile unit enables aggressive techniques and subtle nuances, all while maintaining tuning accuracy. Those upgrading modern or classic setups will find this model delivers premium reliability and fluid action in the 7-string category.

What makes this product unique in its category

A notable feature of the system is its combination of a hardened steel base plate, saddles, and string retainers with a 37 mm nickel-plated brass sustain block, boosting resonance and durability. Enhanced hand comfort comes from the low-profile build, and the screw-on stainless steel tremolo arm offers precise response and long-term reliability.

Functional specs for compatibility and stability

Fit and function are priorities: the system offers industry-standard compatibility with most Floyd Rose-routed 7-string guitars (not suitable for Tune-O-Matic/flat-top bridges). A string spacing of 10.67 mm and 12" (304.8 mm) bridge radius guarantee accurate installation and setup.

• String Spacing: 10.67 mm — precise fit for 7-string necks
• Installation is straightforward thanks to the 12" (304.8 mm) bridge radius, matching contemporary fretboard curves
• Double-Locking: — locks both at nut and bridge for maximum tuning stability
• Sustain Block: 37 mm nickel-plated brass — increased sustain and rich tone

Key build materials and user benefits

Each component is engineered for longevity. Hardened steel is specified for the base plate, saddles, string retainers, and screws, while the tremolo arm is stainless steel for smooth, rust-resistant operation. Reliable tension is provided by coiled steel springs, and the included locking nut and mounting hardware ensure secure installation.

• Long service life is achieved with hardened steel for the main structural parts
• Tremolo Arm: Stainless steel screw-on — smooth and durable
