Liquid Mercury Phaser combines an 8 stage analog optical phaser with a digital microchip (Electric Druid’s TAPLFO) providing modulation with multiple wave shapes and a tap tempo function.
The phaser circuit is derived from the Mutron Phasor II, adapted to operate with 9V supply and augmented with 2 additional non-swept phasing stages.
The phaser was built in in two different versions. One with identical phase capacitors, for a classic phasing and one with staggered capacitors as found in the Uni-Vibe phasers. The second one has a less pronounced phasing effect but a swirlier sound.
I could not really decide which one I like best so I will keep both on my pedalboard 🙂
