Livingroom Gear Demos just unveiled this video of this gorgeous-looking optical tremolo, simply called LFO, made by Italian pedal builder Mastro Valvola.

The effect is packed with features, including Tap Tempo, 16 waveforms, and Symmetry control to alter the shape of LFO waveforms.

Inspired by the optical technology of traditional valve amplifiers, the Mastro Valvola LFO is an optical tremolo that evokes the classic vintage sounds of the past, while offering a range of exciting new features.

The classic warm, enveloping modulation that distinguished amplifiers manufactured during the 60s is reproduced by the opto-isolator that lies at the heart of the analogue audio signal circuit. However, the opto-isolator is managed by a digital brain, allowing you to produce effects ranging from traditional tremolo to unique, inspirational waveforms, and experiment with new atmospheres and hypnotic effects that have never been heard before.




Main features:

  • 16 different waveforms
  • Symmetry control to alter the shape of LFO waveforms
  • Tap Tempo with 3 selectable divisions
  • Opto isolator variable resistance path as used in many classic amplifier circuits of the 1960’s
  • Power supply: 9V/100 mA
  • Size (L x W x H): 9 cm x 11 cm x 6.6 cm
