Product Overview:

The Prussian Blue Reverb Revival is a limited edition pedal commemorating the 15th anniversary of One Control. It reissues the original design of the acclaimed Prussian Blue Reverb, developed by legendary designer Bjorn Juhl. This pedal was created to offer the most natural and expressive reverb tone possible, specifically tailored for guitar and bass.

 

What Is the Prussian Blue Reverb?

Reverb is the gentle echo produced when sound travels through space. Every instrument, whether electric, acoustic, or electronic creates this natural effect before sound reaches our ears. The Prussian Blue Reverb is designed to replicate this ideal echo with clarity, subtlety, and spatial depth.

Unlike traditional reverb types like spring, hall, or room, the Prussian Blue Reverb creates a balanced tone that combines the best elements of each. It delivers a sound that feels alive, three-dimensional, and naturally integrated with your playing.

Rather than imitating classic reverb units, this pedal uses a custom algorithm designed by BJF to respond directly to guitar and bass performance. It avoids harshness and artificial coloration, allowing the instrument’s character to shine through.

 

Key Features:

Reverb pedal with an original design by Bjorn Juhl

Deep, natural, three-dimensional spatial diffusion

Precisely tuned DECAY control that blends naturally with your playing

KILL DRY switch for use in parallel effect loops

Twenty-four-bit high-quality digital reverb processing

Analog dry-through circuit for pure signal path

Compact, durable aluminum mini enclosure

Battery or external power supply compatible

 

Controls:

LEVEL: adjusts the volume of the reverb effect

TONE: adjusts the brightness of the reverb

DECAY: controls the duration of the reverb from two milliseconds to two seconds

KILL DRY: mutes the dry signal for parallel routing or creative effects

The DECAY control is specially designed to shape the reverb’s presence without interfering with the rhythmic clarity of your performance. This makes it ideal for both subtle ambience and long, immersive trails.

 

Sound Design and Technology:

The Prussian Blue Reverb’s algorithm uses random modulation to replicate the natural decay and diffusion of string instruments. This method creates a reverb that feels spacious, musical, and lifelike without sounding artificial or distracting.

The early reflections are short, ensuring the reverb responds quickly to your playing while maintaining a natural decay. This results in an immersive experience that expands the sound without overwhelming it.

Its wide dynamic range, about five times greater than traditional spring reverbs, ensures clarity across all frequencies, especially on bass instruments. Filtering prevents excessive treble or muddiness, keeping your tone open and clear.

*Adapter and Battery not included

 

Power-On Note

Upon powering the unit, allow a few seconds for the internal digital chip to stabilize. During this time, the sound may not be stable. For best performance, wait a few moments in bypass mode after connecting the adapter or battery.

 

Recommended Useage:

The Prussian Blue Reverb was designed specifically for guitar and bass, but it also works beautifully with acoustic instruments and electronic setups. It is particularly effective when placed after distortion effects and before modulation like tremolo. Its ability to stay on at all times makes it a versatile part of any signal chain, from subtle ambiance to spacious soundscapes.

 

Final Thoughts from the Designer:

When developing the reverb effect, I focused on the type of reverb guitarists actually want. In many cases, players desire a tone that lies somewhere between spring and hall reverb, rich but not overpowering, ambient but clear.

That is why I created an accurate DECAY control that can be adjusted to avoid interfering with rhythm, while still providing depth and texture. I had high hopes, but even I was surprised when I first heard the final sound of the Prussian Blue Reverb. It feels like there is a vast space hidden inside this small pedal.

Because it is built specifically for guitars and basses, it suits not only electric instruments but acoustic ones as well. One of my favorite setups is running the PBR after distortion and before tremolo because it sounds absolutely incredible.

As advertised for once! Lol
Color: Cooling Blue Cover, Size: Queen (Pack of 2), Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Queen size set of 2 pillows, I'm giving it 5stars first bc it has a good length and width!! If you've ever bought memory foam pillows before you know some are small!! Anyways after having it for 5nights, we loved that me and my huddy could adjust the Thickness amount we had in it to our needs, me needing a thick pillow and my husband needing a flatter one. So this was perfect for that. So far its nice to sleep on, stays cool, doesnt get hot. I would say its on the frimer side but softer the more foam you take out! Really its just good for the amount you spend!! Will it last 10years probably not but what does now a days. This is the only time my huddy n I bought the same pillow and both love it so I'm just still in shock it worked out so well!!

Adjustable pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
I love these because they don't go flat. You can pull out whatever you need to make them comfy for you. They come in two different layers. So you have that protective cover over the main case that holds the memory foam. They're amazing to sleep on. I have had these last for years without going flat. If you hate flat pillows this is the way to go. They are very easy to wash. You just have to separate layers. They are very thick, you can adjust the thickness. Everyone in my house has at least one. They are worth the money. I have never had to replace them, because they went flat.

Good pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Takes some getting used to but and the cooling doesn’t last very long in my opinion, but overall amazing comfy pillows. The materials are good and are washable. I mostly stopped waking up with a stiff neck and back.

Believe the Reviews
Color: Cooling Blue Cover, Size: King (Pack of 2)
I purchased these pillows because we were in need of new pillows, I previously had allswell pillows which were from walmart and they were good to start but now they tragically became very sparse and it started to effect my sleep so I saw these after careful review on other pillows and reviews I came across these and I saw some reviews and videos and I ordered them.. first they are king size we ordered they are perfect for the bed, they are plump and soft, they are memory foam which has always worked out for me for support and kept it’s shape these are great it did have a little smell I guess from packaging but other than that they are a huge upgrade from what we had before! I’m excited because they are cooling too! for the price point can’t beat it and this is coming from someone who was about to spend money on a purple pillow this will be good for now definitely buy it.

Inconsistent
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Ive ordered two different batches of these pillows, the first was a 2 pack, the second batch was a 4 pack. The pillows that came in the 2 pack have a different quality to them. The memory foam feels thicker, takes long to depress and to spring back to form. It offers more resistance, a heavier odor (at the start), and was the pillow that I fell in love with. Things changed when I ordered the 4 pack a couple months later. There was an inconsistency between the foam in these two different batches. both sets of pillows are comfortable. The first batch being firmer means I had to remove more foam before it became comfortable but the 2nd batch being more springy, I was able to keep all the foam inside. I docked a couple stars because I’m not able to provide a consistent experience with these pillows across all three beds in my home. If you need a pillow, order a set and be happy. If you want a bunch of memory foam pillows throughout your house, maybe look elsewhere as these may not all be identical.
