The Mastro Valvola LEM Lysergic Emotions Module is a multi-head delay pedal with 8 effect modes, designed to inspire dreamy and experimental ambiances. Pedal of the Day's reviewer described it as packing "a boatload of delay options into an extremely pedalboard-friendly enclosure"1. It sits in the wider family of delay pedals, and Mastro Valvola also makes the related TimeLab and LEM pedals.
What it does
The LEM's 8 modes cover a broad spread of delay territory. According to Pedal of the Day, it is easy to run into unique, hypnotic or unexpected sound environments like shimmering repeats, reverse delays, multi-head modulations, pitch shifting and lo-fi sounds1.
Control options go beyond the front panel. There are 4 on-board presets as well as a secondary control section, and tap tempo allows you to adjust what you are doing on the fly. External and CV control add more options into the mix1.
"Not only is the LEM a wonderful delay, it adds in so many exciting ways to tweak and twist your sound"
