No need to be an insider to understand the effect of reverb, come into an empty room, clap your hands and the sound produced by your hands will reach your ears in different ways. The delay is very short because the sound spreads relatively quickly so the delay will not be noticeable (
This type of reverb comes from an acoustic phenomenon, the sound emitted by a speaker will be broadcast according to a cone of propagation. Basically if you are in front of the speaker, you receive everything right in the teeth but at the same time, the sound spreads around the speaker so you will receive this data with a really short delay following a few rebounds on the walls. The bounces that can be seen on this drawing.
At the input of the system, we want to transform an electric guitar signal to a mechanical disturbance propagated in the spring by creating a mechanic oscillation.
In order to achieve this, we will use what is called a transducer. It is on the electronic side a coil that captures and stores the electric guitar signal and on the mechanical side, a system that will disrupt the magnetic field so that the springs will begin to move.
And this lamination goes around the magnets to which the springs are attached. This disturbance will create a magnetic field, oscillating with a waveform really close our electric field. This oscillating magnetic field will then provoque a movement of the magnet of the springs and then this is how your springs finally move according to your guitar playing.
This is the same phenomena but on the opposite way! The springs oscillate to your guitar waveform and also has bounces thanks to rebounds on each side of the tank. Then the magnetic field of the lamination is disturbed because of the oscillation of the magnetic and this will create an electric signal on the output coil.
As the spring will diffuse the different waves, it will at the same time receive input disturbances from our transducer, while the output signal will bounce on its fasteners. The different signals will mix and create a very atypical sound. Each system therefore has its own characteristics that depend on the materials used, the stiffness of the springs and their size.
Your guitar will first enter the tube to get some gain and probably correct some frequencies. Taking in consideration that the 12AT7 has an output impedance of about 20kOhms when its triodes are in parallel, as on this schematic. (to be confirmed by those who work with tubes more than me)
Therefore, the output signal of the tube will not be adapted to enter the spring tank, it will need to use a transformer to go from 20 kOhms to 8 Ohms.
You get it, the signal that enters into the tank is over-vitaminized! Due to its low impedance, the current is very important. He got every good characteristics to be able to go through the transducers in the perfect way and drives perfectly your springs.
On the other side, the output side of the spring tank is not that lucky, we have to recover a weak signal because of the mechanical and transducers lost. So we apply our beautiful layers of make up to give it a second youth.
But do not worry, the solution is very simple! Leave the input close from the 60 cycle and put the output at the opposite side. Or, stick your spring tank into your speaker cabinet and run a cable from your amp to your cable. You can use at maximum a 20m mini-jack to RCA cable. In addition, we are working on a video or an article filled with tips and tutorials to show you how to connect your tank safely ?
That heavy reverb may be consistent with some of Peter Green's recordings but I was instantly brought back to listening to B.B. King's late 60s live recordings - No fear of reverb there and sounds are not at all clean!: Night Life
This might be a stupid thing to ask so forgive me - you tried any of the Reverb effect presets? I always go to presets when I'm having trouble dialing stuff in. "Spring Fan," I assume, is set up to get a fendery-spring reverb. I usually either start there or with "Surf" or "Large Spring" based on the sound I'm going for, and tweak from there to taste.
The thing is it is dead simple to get great reverb sounds out of a Fender or similar amp. Even stand-alone Fender tube reverb units only have three controlls: dwell, mixer and tone. I guess it is nice to have greater control over the reverb sound but having so many parameters also makes it more difficult to dial in.
Of all the reverb types, spring has been the hardest to emulate well digitally. That's not to say people haven't done it. Source Audio's True Spring and Wampler's Faux Spring reverbs are examples. I was futzing with the spring in the KPA last night and got some cool tones, but then again I wasn't trying to emulate any existing sound.
Interested to hear other takes on this conundrum.
A spring reverb is built into a lot of classic guitar amplifiers and is consequently often used for guitars. But you wouldn't do it justice to think a reverb of this type was limited to guitars only. It can add a lot of personality and character to a vocal track, a snare drum, percussion, an electric organ or just about anything. It's very much a sound of its own and it will help set your mix apart from the rest.
We included a few settings so you can choose which spring reverb character you're after. The number of springs and their tension highly affects the sound and feel, so it's up to you to determine what your track needs. There are also tube-driven Bass and Treble controls to further affect the sound.
Ever dropped your plugged in amp by mistake? If you want that explosive boom you'll get from shaking a true spring reverb (making the springs bounce and slam into each other), you can have that too (without smacking your computer).
The RO-SPR is an authentically modeled vintage spring reverb thatadds character and just the right amount of psychedelic flair toyour productions. Experience the iconic sound of Hendrix & co.with its 6 spring types, a three-band EQ, as well as spring lengthand mode control.
It was the year 1939, when Laurens Hammond applied for the firstpatent of an innovative, synthetic reverberation unit, that wasabout to revolutionize the sound of recorded music. With a simpletransducer at one end of a metal spring, and a pickup at the other.
Mr. Hammond further implemented his idea of a mechanical,spring-based hall processor, that found its way into the legendaryHammond organs (from 1960), as well as into standalone hardwareunits like the Accusonics Type 4 SR. Leo Fender made the conceptfamous, with his introduction of the 1963 Fender Vibroverb.
The Spring Reverb is one of the most used hardware reverbs instudio history, but unlike bulky plate reverbs that could easilycost thousands of dollars, and weighed around 600 pounds each,most spring reverbs are more space- and cost-efficient.
We have implemented a versatile signal routing system that allowsfor mono and stereo processing as well as an M2S mode, whichcreates width from mono/stereo sources. In stereo mode, theleft/right signal is sent to independent springs, whereas in M2S mode,the mono signal is sent to non-identical springs to create bespoke width.
In order to further tame the very specific spectral behavior ofthe spring, we have added a 3-band EQ to this plug-in. As springstend to be naturally low-end heavy, with less mids or high-end,this can be equalized in the EQ section.
MR Spring Reverberation System is based on convolution technology together with digital signal processing resulting in a vintage sounding dynamic reverberation effect.
The IR samples has been carefully captured from the very same vintage spring reverb unit from which the inspiration for this device came from.
Spring reverbs work by feeding the input signal, typically from an effects/aux send, to a transducer that 'excites' one or more of the springs. The signal travels down the spring and is picked up by another transducer at the other end, then sent to the output and on to the effects return. But it's not quite as simple as that, as the signal also 'bounces' back along the spring, colliding with other signals on their way down and causing complex pseudo-reflections. We perceive this as a reverb effect, and the more springs a unit has, the more diffuse the reverb effect is.
A more elaborate solution is to run the effects/aux send that is feeding the GBS via a limiter set pretty hard, so that the signal never reaches the level that will cause the springs to become unstable. Many more expensive spring reverbs had just such a facility built in.
Unfortunately these things take up space, but I've had good results. I used to love the spring reverb in my mixing board, before it stopped working. Erm, yeah, that's another downside. Maybe it's best to stick with software solutions.
On the other hand, there is space (no pun) for further experiments in order to get good "real" reverbs. Imagine how the reverb might sound if you stand in a room and clap your hands, and then try to synthesize this reverb tail with some synthesizer. I guess you will need filtered noise and an envelope with short attack and long decay, but really, listen to real rooms and try.
hey fader 8 I just saw on that link above (not the noise vault) that they have impulses of the UAD 1 spring reverbs. anyway you could compare those to the actual UAD card and let us know how accurate they seem to be. I am very curious about how close the IRs in space designer compare to real thing (although I am blown away by all the Lexicon and Kurzwell Irs I've heard so far) Never heard the real thing tho.
