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.

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.

BEST TOY!
Style: White, Size: 6"
I recently bought the Multipet INTERNATIONAL 843140 Lambchop Plush Squeak Toy Mini for my small dog, and it has quickly become her favorite toy. Here’s why this little squeak toy is a great addition to any pet’s collection: Adorable Design The Lambchop Plush Squeak Toy is absolutely adorable. It resembles the beloved character Lambchop, which adds a nostalgic charm for those who remember the classic TV show. The toy is well-crafted with a cute, friendly face and soft, plush material. Its small size makes it perfect for petite pets, and it’s just the right size for my dog to carry around and snuggle with. Engaging and Fun The built-in squeaker adds an extra layer of excitement for my pet. Every time she bites down, the squeak captures her attention and keeps her engaged for longer periods. It’s great for interactive play, fetch, and even as a comforting chew toy. My dog loves the noise it makes and often brings it to me to initiate playtime. Durable Construction Despite its soft and plush exterior, the Lambchop toy has proven to be quite durable. My dog is a moderate chewer, and after several weeks of play, the toy is still intact with no signs of wear and tear. The stitching is strong and has held up well against my dog’s playful bites and tugs. However, for very aggressive chewers, it might not last as long. Easy to Clean The toy is also relatively easy to clean. I’ve hand-washed it a few times to keep it fresh, and it dries quickly without losing its shape or squeak. The white color, while prone to getting dirty, can be easily spot-cleaned to maintain its appearance. Perfect Size for Small Pets At 6 inches, this toy is ideally sized for small dogs and even cats. It’s lightweight and easy for them to carry around. My dog can comfortably grip it in her mouth, and the toy is soft enough for her to cuddle with during nap time. Value for Money Considering its durability, engaging design, and the joy it brings to my pet, the Multipet Lambchop Plush Squeak Toy offers excellent value for money. It’s reasonably priced and provides hours of entertainment and comfort for my dog. Overall Impression Overall, the Multipet INTERNATIONAL 843140 Lambchop Plush Squeak Toy Mini is a fantastic toy for small pets. Its adorable design, engaging squeaker, and durable construction make it a worthwhile purchase. My dog loves it, and it has quickly become a staple in her toy collection. I highly recommend this toy to anyone looking for a cute and fun squeak toy for their small pet.

Great, but a little big…
Style: Lambchop, Size: 10"
Super soft and cute, I got this for my toy Cavapoo puppy. The different textures are perfect. It is a little bigger than I was expecting, and will probably be about the same size as my puppy when I get her, but I’m sure she’ll love it. I don’t know how safe it will be yet since I’ve yet to be able to watch her play with it, but I don’t see anywhere that could have loose strings for her to choke on, so I’d say it’s pretty safe. Overall a perfect toy for dogs, with a squeaker and nice textures for the dog to chew on.

Great value for the price
Style: White, Size: 24" Jumbo
I have gotten smaller versions of this Lamb chop, my dog has loved them all the same but this one is great. It's big enough for him to carry around and it lasts a lot longer since he likes to tear them up fast.
