The Stereo Sunlight is a modulated stereo reverb pedal from Old Blood Noise Endeavors, hand-made in Oklahoma, USA1. It is a full stereo evolution of the company's mono Sunlight reverb, combining elements of the Sunlight and the Procession into one pedal with added features1. RockBoard's PedalPedia describes it as a dynamic hold reverb designed to create evolving ambient textures, with three reverb modes and responsive hold functionality that reacts to playing dynamics2.
Guitar Pedal X's Stefan Karlsson reported it as the fourth pedal in OBNE's Square Stereo Series, following the Dark Start, Black Fountain and Bathing Liminal1. Delicious Audio's Paolo De Gregorio called it "a stereo powerhouse that brings lightness, exhilarating motion, and a profound dynamic response to your sound," and positioned it as a counterpart to OBNE's Dark Star3.
What it does
The Stereo Sunlight is a reverb with modulation built in. RockBoard describes it as a dynamic hold reverb: the hold functionality responds to playing dynamics, letting you sustain and evolve ambient textures from your own touch2. It carries over the Sunlight's character while adding true stereo processing and additional control over modulation and filtering compared with the original mono pedal2.
Guitar Pedal X notes that it combines two of OBNE's ambient pedals, the Sunlight and Procession, "here enhanced with further features"1. Karlsson also observed that each Square Stereo Series pedal is its own kind of complex, potent multi-FX, and that while the series members are distinct, they function as something like direct competitors with each other1.
The controls
The pedal's knobs cover the dry signal, the reverb's decay and character, and the modulation section. Press coverage lists the control set as follows1:
| Control | What it does |
|---|---|
| Dry | Sets the level of the dry signal |
| Dynamics | Shapes how the hold functionality responds to playing dynamics |
| Decay | Sets the reverb's decay time and character |
| Feedback | Sets feedback in the reverb path |
| Rate | Sets the modulation speed |
| Depth | Sets the modulation depth |
| Shape | Selects the modulation waveform: Tape, Triangle, Square, Ramp Up, Ramp Down or Random |
| Time | Sets reverb time |
| Frequency | Filters the reverb character |
| Wet Level | Sets the level of the wet reverb signal |
The Shape control's six waveform options give the modulation section a wide range, from tape-style wobble to random stepped movement1. RockBoard summarizes the shaping controls as decay, input, filter and rate for shaping the reverb character2.
Two footswitches handle the rest. An aux footswitch covers tap tempo, reverb hold and preset switching, alongside a standard on/off footswitch1. An expression jack allows external control over selectable parameters, and the maker's page states there is expression control over every knob42.
Stereo routing, MIDI and power
The Stereo Sunlight runs stereo in and out with analog dry through, meaning your dry signal stays analog rather than being converted4. The TRS stereo input offers the option of mono or mono-in-stereo-out routing, so a single mono feed can drive a stereo output into two amps1.
Connectivity goes well beyond the jacks1:
- MIDI in and MIDI out, with MIDI clock in and out for external tempo sync
- MIDI control over all parameters
- USB-C port
- Expression input with control over all parameters
- Onboard presets
The power requirement is worth noting for pedalboard planning. The pedal requires a 9V DC center negative 2.1mm jack power supply capable of 350mA, and the supply is not included4. At 350mA it is a relatively hungry pedal, so check that your power supply has an isolated output with enough current before building it into a board.
The 350mA current draw rules out a battery and means the pedal needs a dedicated high-current output on a powered pedalboard rather than a shared daisy chain41.
The bypass is selectable between Buffered Trails and True Bypass modes, so you can decide whether reverb tails ring out after bypassing or the signal path is cut clean1.
Versions and finishes
The standard model is the Maroon finish1. RockBoard's PedalPedia also lists a Black version and a limited Yellow edition of the Sunlight Stereo52. The compact enclosure has top-mounted jacks for pedalboard integration2.
Where it came from
The Stereo Sunlight grows out of two earlier OBNE pedals. The mono Sunlight provided the reverb architecture, and the Procession contributed elements of its ambient character, with the Stereo Sunlight adding stereo processing, presets, MIDI and deeper modulation and filtering control12. Delicious Audio frames it as OBNE expanding the sonic palette of the original Sunlight reverb3.

Questions
What is the difference between the Sunlight and the Stereo Sunlight?
The Stereo Sunlight is a full stereo evolution of the original mono Sunlight. It adds true stereo processing with stereo in and out, plus additional control over modulation and filtering, onboard presets, and MIDI. It also combines elements of OBNE's Procession pedal with the Sunlight's reverb architecture.
Does the Stereo Sunlight have trails?
Yes. The pedal offers selectable Buffered Trails or True Bypass modes, so you can choose whether the reverb tail continues to ring out after you switch the effect off, or whether the signal path is fully bypassed.
Can the Stereo Sunlight run mono in, stereo out?
Yes. It has TRS stereo input and output jacks with the option for mono or mono-in-stereo-out routing, so a single mono input can feed a stereo output pair into two amps or a stereo rig.
How many presets does the OBNE Stereo Sunlight have?
The pedal has onboard presets, and all parameters can also be controlled over MIDI. The maker's product page lists presets as a feature, and press coverage confirms onboard preset switching via the aux footswitch, alongside full MIDI control.
What colors does the Stereo Sunlight come in?
The standard model is the Maroon finish. It has also appeared in Black and in a limited Yellow edition, according to RockBoard's PedalPedia listings for the pedal.
