Lyria is a gorgeous 100% analog harmonic tremolo pedal. Harmonic tremolo is an effect that I have loved forever. Possibly my favourite form of modulation. The sort of modulation that instantly makes things sound magical and beautiful. Lyria uses a set of matched FET transistors to control the amplitude modulation of two parallel signals. One signal is a high frequency signal, the other a low frequency signal. Modulation has always been at the forefront of my designs, from the Moon Phaser and Empress Deus Chorus right through to the recent Eleutheria limited edition Flanger pedal. It has been a real pleasure to turn my focus towards the prettiest of all modulation modalities.
