Bjorn's Description

The History

A reverb effect simulates a mild reverberation that is created when a sound is reflected in space. Every sound the is emitted for any instrument instrument accompanies reverberation in space before reaching human ears.

The PRUSSIAN BLUE REVERB creates an ideal and genuine reverberation. Acoustically, the most prestigious music venues are designed with the perfect reverberation in mind. Technologically, creators may use plates, springs and digital reverb in order to pursue the ideal reverberation.

This reverb pedal is different from other effect pedals that cloned historical simulations and reverberation styles. I wanted to create a reverb effect that would be wanted by guitar and bass players.

The Design

What I didn't want to do was create an overbearing and powerful spring reverb or a reverb tone produced as a deluding effect at an higher octave. I wanted to pursue the ideal reverb tone but also wanted to highlight the instrument. The custom program is recorded on a 24-bit digital chip. Its dry signal is analog, which is not converted to digital.

Ideal reverb tones for guitarists and bassists are neither spring, hall, nor room. I've created a mixture of all their strengths and brought them to the forefront. To put in more relative terms, it’s closer to the hall tone than to spring but not as bright as hall reverb. See what I mean?

By randomly modulating the decay time of reverb signals, it creates the effectsby which sounds spread in the space while remaining mono. This random modulation is programmed to imitate the string vibration property of guitars and basses. This is a property unique to the PRUSSIAN BLUE REVERB, different from the conventional reverb algorithm that creates layers of individually recorded reverberation. It is natural and solid but not too plain, and is most similar to "the" reverb tone players constantly seek.

The Reverb

The PRUSSIAN BLUE REVERB has the dynamic range that is five times larger than a general spring reverb. It is filtered to prevent it from having too much tremble or saturation. A broad dynamic range is essential to create an open spatial property.

At the same time, decay control was added to prevent reverberation from interfering with rhythm. The decay control designed by BJF does not simply adjust the overall reverb length. The decay time can be set from 2ms to 2s. In simpler terms, choose between a soft reverberation or a long-lasting reverberation. This decay control combined with the natural reverb is similar to studio-grade reverb thanks to the technology present in this pedal.

The PRUSSIAN BLUE REVERB’s early reflection is set to be short. Thanks to the short duration between the guitar/bass attack to the reverb startup and the overwhelmingly natural reverb tone, unnatural reverb is simply not present in the final outputted sound. The PRUSSIAN BLUE REVERB allows you to mute a dry signal with the Kill Dry switch. While it is a common function among rackmount reverbs, it is also effective when it’s connected to a parallel effects loop on some guitar amps and mixers. If you connect the PRUSSIAN BLUE REVERB with the Kill Dry on to the main signal chain, you can use it to create slow volume effects by setting the early reflection to short. It is important to note that it takes several seconds from the time the power is turned on until the digital chip inside is stabilized and starts running. The tone may become unstable during this period, so please maintain the bypass for several seconds after connecting an adapter.

This pedal is designed for guitars and basses. It is not only suitable for electric guitars and basses but also for acoustic guitars and basses as well.

PBR provides the best sound when it’s connected after distortion effects and before tremolo effects.

When developing reverb effects, I always put the guitarists' vision first, not mine. For this reason, I chose a balanced reverb tone and added more precise decay control that will not interfere with the rhythm.

I was confident but when I actually heard the tone of the PRUSSIAN BLUE REVERB made, I was speechless. It's as though the sound travels in an unlimited space which gives you endless creative opportunities. ou can say that there is unlimited space expanding in this small pedal.

Might be the Goldilocks blanket
Color: 04 - Sage Green, Size: Throw (50" X 60"), Color: 04 - Sage Green, Size: Throw (50" X 60")
Everybody loves these blankets. Couch throw or super comforting blanket on top of bed covers. My wife selected the first. Now we own 4 or 5. Wife, son, couch, gifts to niece and father. Easy to wash; comes out new again. Doesn't feel cheap or low quality textile like. Feels great light-medium weight! Not too hot. Not too thin or light. Just might be the goldilocks blanket.

Great buy, soft, fluffy, great colors, warm, fun!
Color: Purple, Size: Queen(90"x90")
This is a very very soft queen blanket, just what I wanted. The dark purple color is what I wanted as well. As I put it on the bed the 1st time I noticed a lot of "fluff" in the air & on the sheets. So I washed it just to a)get the extra "fluff" off and b) to get the bubble effect more fluffy. It came vacuum packed and wasn't as fluffed up as I'd hoped. So, It washed beautifully and I put it in the dryer with 4 wool balls & scent drops I'd also ordered from Amazon. I used this instead of a softener sheet because I read that the wool balls make laundry softer, static free and smelling fresh & in the case of this typeblanket or throw, fluffier. The blanket came out of the dryer perfect! Much softer, much fluffier - you could really notice the bubbles - and there wasn't much lint in the lint catcher, but it was enough to stop it from shedding little fluffy bits! I have this blanket on my bed now. It's warm, lightweight, and the bubbles and color make me smile when I look at it. Very happy with purchase!

Small and so cute
This blanket is so cute and perfect for adding a cozy touch to any space! The color is a rich, warm brown that looks great with my other decor. It’s small, but that’s what makes it perfect as an accent piece—it looks amazing draped over a chair or folded on a shelf. The material feels soft and high-quality. It didn’t have any weird smell after opening it. I would say it should be used more for decoration than everyday use. It adds just the right amount of texture without being bulky or taking up too much space. Works perfect as a drape over side of bed, chair, or blanket ladder. For the price, I think it’s a great find. It’s stylish, simple, and really ties the room together. If you’re looking for an affordable way to elevate your decor, this is it!

Cheap material
Color: Ivory, Size: Throw(50"x60")
Does not look like product pictures. Different design and texture. Kept anyway because I chose more for color. After washing a couple of times, these blankets appear VERY worn. They're thinner than preferred and don't wear well. A cheap product for a cheap price. The color was as expected though.
