About This Item
Description
The Meris LVX breaks from fixed delay presets entirely, letting you connect processing elements and control-signal modifiers however you like for up to 2540 ms of configurable dual delay, plus an always-available true stereo looper.
Which Meris LVX is this?
LVX is a modular delay system: you connect discrete processing elements and control-signal modifiers however you like for up to 2540 ms of configurable dual delay, with a color screen, 99 presets across 33 banks, a true stereo 60-second looper, an instant tuner, and native 5-pin DIN plus USB-C MIDI. Meris borrows many processing elements for LVX from the Polymoon, Hedra, and Enzo, but states plainly that LVX "cannot completely replicate the unique effect engines" of those fixed-architecture pedals — Meris recommends pairing LVX with a Polymoon (available separately as its own pedal on our site) for even greater possibilities.
Why guitarists choose the LVX
- Modular architecture lets you patch processing elements and control-signal modifiers however you like, instead of picking from fixed delay presets.
- Up to 2540 ms of dual delay covers everything from tight slap-back to long ambient trails.
- Always-available true stereo 60-second looper works independently of the delay engine.
- Color screen and 99 onboard presets make deep patches easy to build, name, and recall.
- Instant-access tuner is available without leaving your patch or stepping on an extra pedal.
- Native 5-pin DIN MIDI In/Out plus USB-C give full remote control with no external converter box needed.
Controls and switches
- Time — Sets the base delay time, up to 2540 ms depending on the structure and processing elements loaded.
- Feedback — Controls how many times the delay repeats feed back into themselves for shorter slaps or long, cascading trails.
- Mix — Blends delay output with your dry signal.
- Mod — Applies modulation depth to the loaded processing elements for chorused, pitch-shifted, or textured repeats.
- C1 / C2 navigation encoders — Select and edit a favorited parameter directly from the front panel without diving into a menu.
- C3 encoder — Turns to change presets, pushes to enter edit mode, and holds to save — the main way to browse LVX's 99 presets across 33 banks.
- 4 LED buttons (1, 2, 3, Tap) — Mirror the four footswitches for desktop and studio use without reaching for the floor.
- Footswitches 1, 2, 3 — Engage or bypass presets in normal play; in Looper Mode they become Record/Overdub, Play/Stop, and Loop FX 1.
- Tap footswitch — Taps in delay time and syncs MIDI beat clock; hold to enter the always-available true stereo 60-second looper, where it doubles as Loop FX 2.
Power and pedalboard compatibility
LVX runs on 9V DC, center-negative, 2.1 mm barrel, drawing at least 300 mA — use an isolated multi-output supply rated for that current; Meris lists its own 9V supply, the MXR Mini Iso-Brick, MXR Iso-Brick, and Cioks DC7 as tested-compatible. The relay true bypass is mono only; running true stereo I/O, Trails, Spillover, or Kill Dry automatically switches LVX to Analog Buffered Bypass, so plan pedalboard placement around whichever bypass mode your patch uses.

FAQ
How much delay time does LVX have?
Up to 2540 ms of highly configurable dual delay, depending on the structure and processing elements you load.
Does LVX have a looper?
Yes. An always-available true stereo 60-second looper, entered by holding the Tap footswitch.
Can LVX replace my Polymoon?
Meris says LVX "borrows many processing elements from the Enzo/Hedra/Polymoon, however it cannot completely replicate the unique effect engines," and recommends pairing LVX with a Polymoon, Hedra, or Enzo rather than replacing them.
Does LVX work with the Meris Preset Switch?
No. The Preset Switch is officially listed as compatible only with Ottobit Jr., Mercury7, Polymoon, Enzo, and Hedra; LVX handles presets from its own front panel and over MIDI.
Does LVX need the Meris MIDI I/O box?
No. LVX has its own 5-pin DIN MIDI In/Out jacks plus MIDI over USB-C on firmware 1.5 and later, so no MIDI-to-TRS conversion box is required.
What power supply does LVX need?
9V DC, center-negative, 2.1 mm barrel, at least 300 mA. A power supply is not included.
How do I update LVX firmware?
Hold footswitches 1 and 3 while powering up, connect the rear USB-C jack to a computer, drag the extracted firmware file onto the LVX drive, eject, then power cycle.
