The Ibanez TZ6 / TZ II is a standard 2 pivots tremolo with knife-edged pivot points, carbon steel 10.5 mm saddles and a large brass sustain block. The TZ-6 and TZ-II differ in their sustain block. The TZ-6 has a cast iron sustain block whereas the TZ-II has a massive solid brass sustain block. Later this tremolo model was replaced by the Ibanez TZ-30 tremolo.
