Product Overview

The Tone Claw is a robust spring claw engineered with a locking clamp plate to lock the springs down at the hoop ends. CNC-machined from solid brass and at 4x the mass of a traditional claw, the Tone Claw is designed to increase sustain and enhance tonal qualities while also aiding tuning stability by preventing the springs from shifting or popping out during heavy tremolo use.

With a traditional claw, the vibrational energy transferred from the sustain block through the springs dissipates as it reaches the claw because of the poor contact area between the spring hoop ends and the standard claw tabs, as well as the thinness of a standard tin plate. The Tone Claw's locking clamp plate, in conjunction with the form-fitting posts (where the spring hoop ends connect), significantly increases the contact between the springs and claw. Instead of ending its path, this vibrational energy from the springs is transferred into the Tone Claw and sent back through the springs and into the sustain block thus improving sustain.

Installation is easy and a direct swap for most existing spring claws such as those from Fender, Floyd Rose, PRS, Ibanez, and many others. The kit includes the Tone Claw base and sliding clamp, two claw mounting screws, and four quality coiled steel tremolo springs. An adjustable ground soldering tab is also integrated which can be switched between two available mounting holes depending on the required orientation. Available in either raw brass or a nickel-plated finish

Please measure your spring cavity to ensure a proper fit before ordering!
