The Spaceman Effects Meridian Time Modulator is an analog modulation pedal that blends aspects of chorus, vibrato, flanger, filter, pitch-shifting and more into one pedal1. Its heart is a flexible 1024-stage bucket brigade delay line built on the MN3007 chip, with a delay range of 0.8ms to 50ms, which is enough to produce a variety of classic chorus tones1. The signal path adds pre-emphasis and de-emphasis, companding, and refined anti-aliasing and reconstruction filters1.
What it does to your sound
Pedal of the Day's reviewer described the range of effects the delay line covers: "Experience liquid chorus tones, mind-bending true pitch vibrato and much more," alongside wispy phasing, throbbing Leslie, shimmering flange, static comb filtering and double-tracking1. The same reviewer's verdict on the tone: "For users tired of brittle, piercing modulation pedals, the Meridian offers a clear and articulate tone while providing analog warmth."1
Controls and waveshapes
The LFO section offers three waveshapes, each suited to different effects1:
| Waveshape | Character | Typical use |
|---|---|---|
| Sine | Smooth cycle | Wet-only pitch vibrato, Leslie effects |
| Triangle | The de facto standard | Chorus and flanger sounds |
| Flux | Wobbly, uneven derivation of the triangle wave with unpredictable skips and jumps | Irregular, less predictable modulation |
At minimum, the Width control bypasses the LFO entirely, letting the player sweep the delay line directly with the Rate and Time controls for static comb filtering or double-tracking1.
Expression and CV control is possible using the EXP jack, so an expression pedal or control voltage source can drive the Meridian's modulation1.
Where it sits
Guitar Pedal X has noted that there are more expansive Delay Line Manipulators already out there, naming Cosmodio Instruments Splinter Twin among them, with the Meridian among the pedals in that wider family of delay-line-based modulators2. For players comparing options, the Meridian sits alongside the chorus, flanger and vibrato families rather than replacing any one of them.
The pedal comes in a purple, sparkly enclosure1.

Questions
What is the difference between the Sine, Triangle and Flux waveshapes on the Meridian?
The Meridian's LFO section offers three waveshapes. Triangle is the de facto standard for chorus and flanger sounds. Sine waves are commonly preferred for wet-only pitch vibrato and are also used for Leslie effects. Flux is a wobbly, uneven derivation of the triangle wave with unpredictable skips and jumps, for less regular modulation.
What does the Width control do at minimum on the Meridian?
When Width is turned to minimum, the LFO is bypassed, and the delay line can be swept directly with the Rate and Time controls. That opens up static comb filtering or double-tracking style effects rather than continuous modulation.
Can the Spaceman Meridian use an expression pedal?
Yes. Expression and CV control is possible using the EXP jack, so the Meridian's modulation can be controlled from an external expression pedal or a control voltage source.
What bucket brigade chip does the Meridian use?
The heart of the Meridian is a 1024-stage bucket brigade delay line built on the MN3007 chip, a design long associated with vintage analog modulation pedals.
Is the Spaceman Meridian analog?
Yes. The Meridian is an analog pedal, and Pedal of the Day's reviewer described it as a versatile analog chorus with lush modulation and a timeless vintage character.
