Bjorn's Description

The History
A reverb effect simulates a mild reverberation that is created when asound is reflected in space. Every sound the is emitted for anyinstrument instrument accompanies reverberation in space beforereaching human ears.

The Prussian Blue Reverb creates an ideal and genuine reverberation.Acoustically, the most prestigious music venues are designed withthe perfect reverberation in mind. Technologically, creators mayuse plates, springs and digital reverb in order to pursue the idealreverberation.

This reverb pedal is different from other effect pedals that clonedhistorical simulations and reverberation styles. I wanted tocreate 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 springreverb or a reverb tone produced as a deluding effect at an higheroctave. I wanted to pursue the ideal reverb tone but also wantedto highlight the instrument. The custom program is recorded ona 24-bit digital chip. Its dry signal is analog, which isnot 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 andbrought 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 hallreverb. See what I mean?

By randomly modulating the decay time of reverb signals, it creates theeffectsby which sounds spread in the space while remaining mono. Thisrandom modulation is programmed to imitate the string vibrationproperty of guitars and basses. This is a property unique to thePrussian Blue Reverb, different from the conventional reverb algorithmthat creates layers of individually recorded reverberation. It isnatural 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 timeslarger than a general spring reverb. It is filtered to prevent it fromhaving too much tremble or saturation. A broad dynamic range isessential to create an open spatial property.

At the same time, decay control was added to prevent reverberation frominterfering with rhythm. The decay control designed by BJF does notsimply adjust the overall reverb length. The decay time can beset from 2ms to 2s. In simpler terms, choose between a softreverberation or a long-lasting reverberation. This decay controlcombined with the natural reverb is similar to studio-grade reverbthanks to the technology present in this pedal.
​
The Prussian Blue Reverb’s early reflection is set to be short. Thanksto the short duration between the guitar/bass attack to the reverbstartup and the overwhelmingly natural reverb tone, unnatural reverb issimply not present in the final outputted sound. The PrussianBlue Reverb allows you to mute a dry signal with the Kill Dry switch.While it is a common function among rackmount reverbs, it is alsoeffective when it’s connected to a parallel effects loop on some guitaramps and mixers. If you connect the Prussian Blue Reverb withthe Kill Dry on to the main signal chain, you can use it to create slowvolume effects by setting the early reflection to short. It isimportant to note that it takes several seconds from the time thepower is turned on until the digital chip inside is stabilized andstarts running. The tone may become unstable during this period, soplease maintain the bypass for several seconds after connecting anadapter.

This pedal is designed for guitars and basses. It is notonly suitable for electric guitars and basses but also for acousticguitars and basses as well.

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

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

I was confident but when I actually heard the tone of the Prussian BlueReverb made, I was speechless. It's as though the sound travels in anunlimited space which gives you endless creative opportunities.ou can say that there is unlimited space expanding in thissmall pedal.
