The Mile End Effects Julep Stereo Pan / Phase is an optical stereo pedal that puts panning, tremolo and phasing in one box. Pedal of the Day, covering it, described it as "this optical stereo panning/tremolo and phasing effect gives a wide variety of sounds", covering everything from "syrupy, frothy vibe effects to dizzying, choppy stutters", and noted that it was available for pre-order via the maker's website: "Be sure to hit up their website to pre-order a Julep for yourself"1.
What it does
The Julep runs three related effects from one modulation engine. In stereo, its outputs can be sent to two different effects chains or two separate amplifiers, so the panning movement plays out between two sources1. In mono, it works as what the Pedal of the Day reviewer called "a simple, but versatile tremolo and phaser"1.
The reviewer described the range this way: "a vast sweep in panning/tremolo rate from a slow crawl to a worried tremble and a subtle, vintage voiced phaser that at certain depth settings reaches rotary simulation/uni-vibe territories"1. On combining the effects: "You can use these effects on their own, but they really take off and turn powerful when used in tandem"1.
The controls
| Control | What it does |
|---|---|
| Rate | Sets the panning/tremolo speed1 |
| Depth (left and right) | Individual knobs control the depth of the left and right sides of the tremolo1 |
| Waveform | Moves from triangle to square waveform, exploring everything in between1 |
| Sync/Separate switch | Synchronizes the panning/tremolo between the stereo outputs, or separates the outputs by 180 degrees1 |
| Phase Depth | Controls the depth of the phaser1 |
| Phase Rate | Controls the speed of the phaser1 |
The separate left and right Depth knobs are what make the stereo movement adjustable beyond a simple mirror image, and the Sync/Separate switch decides whether the two outputs move together or against each other1.
Where it came from
By concept, the Julep follows the Ibanez FP-777 Flying Pan. Pedal of the Day described it as "by concept a semblance of the infamous Ibanez FP-777 Flying Pan, but functionally and electronically is an expansion" of it1.
The Julep was a pre-order product as of the June 2022 review, with shipping originally expected around 1 March 2022.

Questions
Can the Julep be used in mono?
Yes. Pedal of the Day notes that you can use the Julep in mono for what the reviewer called a simple, but versatile tremolo and phaser. The stereo side of the pedal, including the panning between two outputs, only comes into play when you use both outputs, but the tremolo and phaser circuits work on their own in a single signal path.
What does the Sync/Separate switch do on the Julep?
The Sync/Separate switch sets how the two stereo outputs relate to each other. In Sync it synchronizes the panning and tremolo between the stereo outputs, so both sides move together. In Separate it offsets the two outputs by 180 degrees, so one side moves opposite the other, which is what creates the swinging stereo movement.
Can I run the Julep into two amps?
Yes. The reviewer at Pedal of the Day describes sending the stereo outputs to two separate amplifiers, or to two different effects chains for a range of panning possibilities. Running one output to each amp is the classic way to hear the pedal's stereo movement.
Is the Julep based on the Ibanez Flying Pan?
By concept, yes. Pedal of the Day describes the Julep as a semblance of the Ibanez FP-777 Flying Pan, but functionally and electronically an expansion of it. The original FP-777 was an analogue mono-in, stereo-out phaser and panner, and the Julep takes that idea further.
Does the Julep have a waveform control?
Yes. The Waveform control moves from triangle to square, exploring everything in between the two, according to Pedal of the Day. That shapes the character of the modulation, from smooth sweeps to sharper, more abrupt movement.
