Calculated at checkout

Sorry but this item is currently unavailable.

Please check back at a later stage.

The LEM offers up to eight ambience types, ranging from a standard reverse delay to a lo-fi spatial ambience delay-reverb. Presets can be toggled via the right footswitch and up to four presets can be stored within the LEM. 

The LEM’s front panel features four knobs for wet/dry, delay and feedback. The fourth Special/filter knob allows the user to control the special feature of each ambience mode, while its secondary function sets the frequency of the analogue filter applied to the wet signal. Going to the left emphasises the low frequencies, while turning the dial to the right brings out more of the medium-high frequencies.

The LEM is a multi-head delay pedal with 8 effect modes, designed to inspire dreamy and experimental ambiances. While playing with this effect, it's easy to run into unique, hypnotic or unexpected sound environments like shimmering repeats, reverse delays, multi-head modulations, pitch shifting, lo-fi sounds and more.

Main features:

  • 8 ambiance types
  • 4 presets
  • True bypass with Timed Bypass System (TBS), to manage the trails and the bypass switching style
  • Separate Dry and Wet controls
  • CTRL input: exp/cv or remote switch

Mastro Valvola - Lysergic Emotions Module (LEM) (12:11)
Here’s the Lysergic Emotions Module, from Mastro Valvola (Italy). It packs 8 different delay modes with secondary effects into a tiny… and very cool little box. There’s pitch shifting, reverse, octave up and down shimmer, vibrato and a few multi delays as well. There’s CV/EXP control, presets and on board/remote tap tempo. There’s so many awesome sounds that range from super gnarly, bit crushed weirdness and then really chill atmospheric settings too! The small footprint and unique delay modes make this one A-OK in my book. Here we’ll go through all the modes and like 90% of the features :) Check it! http://www.mastrovalvola.it/lem/ 0:00 Reverse Vibrato w/ Guitar 1:18 LOFI Reverse Vibrato w/ Guitar 2:29 Filter Reverse w/ Guitar 3:28 Multi-Head Wow w/ Organelle 4:38 Octave Down Bit Crush w/ Organelle 5:30 LOFI Ambient Bit Crush w/ Organelle 6:32 Multi-Head Forward/Reverse w/ Minilogue 8:13 EXP Shimmer Crush w/ Minilogue 9:41 Presets w/ Minilogue GEAR: Fender Stratocaster Korg Minilogue Critter and Guitari Organelle Pigtronix Infinity Looper Apogee Duet 3 Monkeys Solderless Strymon Zuma R300 ***This is a sponsored video***
