Notes: Stereo spring reverberation for highest standards

Stereo and more
Our DSR-3, Dual Spring Reverb, was developed to deliver stereophonic spring reverberation for professional users. Furthermore, we couldn't resist adding creative potential to the unit by including additional operating modes for parallel and serial use.

Matched Pairs
Just like in our valve-based ReTubeVerb, the classic VSR 3.2 and the adventurous Retroverb Lancet, DSR-3 relies on the exceptional sound quality of AccuBell springs (formerly Accutronics). To ensure perfect stereo sound, the springs of DSR-3 are manually checked, selected and matched with great care.

Each channel offers a two band equalizer with BASS and TREBLE controls being carefully matched to the specific frequency range of the springs. Hereby, the effect can be adjusted to your specific needs easily and with great flexibility.

High-level-communication
Besides 6.3mm in- and outputs in jack-format (TS), DSR-3 additionally offers balanced XLR- in- and outputs. Output balancing is carried out by custom-designed transformers with excellent sonic characteristics. As a benefit, DSR-3 becomes a first-class DI-box this way.

Productivity and creativity
Both spring channels can be combined in three operating modes or used independently:

STEREO processes stereophonic audio sources. To ensure perfect matching of the settings, the first SPRING REVERB channel controls all parameters being sonically relevant.
DUAL MONO processes two independent sound sources. Each channel acts independently as if it was a single unit.
SERIAL for experimental spring reverberation effects. The reverberated signal of channel one is routed into the second channel, making long reverb tails possible.

DSR-3 is assembled with loving care in our electroacoustic manufactory in Erlbach, Germany - the so called Vogtland. Using VERMONA's DSR-3 allows creating highest quality lush and full reverberation effects with depth and vintage charm of days gone by.

Notes: Gorgeous analogue goodness in this all-rounder, featuring overdrive, filter, envelope, LFO and a nice retro spring reverb among others processing options. Tons of character.

Supplier's notes:
Today's digital effects and plug-ins can create almost perfect room simulations. However, when it comes to characteristic and charismatic reverb, analogue effect-processors are yet to beat. The reverberating sound of a spring is so lively and unique that its sound is almost impossible to recreate in the digital domain. In addition to this, Retroverb Lancet is not just a spring reverberation system - it is an analogue multi-effects-processor. It offers overdrive, filtering, VCA, envelope and LFO to manipulate the spring sound and create different sounds like auto-wah, tremolo, distortion, delay, gater and of course reverb.

The typical spring reverb sound is generated by a Belton/Accutronics type 4 spring tank with 3 individual springs. It can be placed pre or post the VCF/VCA section and equalized by the Tone parameter.

The Crash function generates the popular thunder effect that occurs when kicking an amplifier with spring tank. You don't have to kick Retroverb Lancet you simply can achieve this effect by pressing the Crash button. It also can be triggered by a Gate voltage.

The multimode filter works as lowpass or highpass with a slope of 24 dB per octave or as bandpass with 12 dB per octave. It is followed by a voltage controlled amplifier. The filter and amplifier can be modulated individually by different sources.

The Retroverb Lancet offers 3 internal modulationGorgeous analogue goodness

Envelope follower: the envelope follower converts the amplitude characteristic of the audio input signal into a control voltage.
Envelope generator: the envelope generator can be triggered by the input signal itself, a second audio signal or a gate voltage. Depending on the trigger source it works as Attack-Decay or as Attack-Sustain-Release envelope.
LFO: the LFO offers saw up and saw down, square, sine as well as sample&hold. Additionally it can use the envelope generators settings as waveform. It can oscillate freely or reset by different trigger sources.

The Retroverb Lancet also offers a CV/Pedal input which can be feed by external control voltages or can be used with expression pedals.

Notes: Although spring reverbs have been built for more then five decades they are still highly desired because of their individualism and sound quality. They can almost be seen as standard for guitar amplifiers and can be found in a great number of studios around the world, as they are also a perfect choice for vocals, organs and synthesizers.

Once again VERMONA presents a tube spring reverb of it's own class and once again the name is "ReTubeVerb". Some details have been improved and there are also strongly requested features like balanced in- and outputs as well as the possibility to get it in a rack system.

Uncompromising Tube Technology:
The ReTubeVerb is build upon classical tube circuitry - you will not find a single semi-conductor in its signal flow. This uncompromising realization needs some efforts but the result justifies the concept! What you'll get is the warm and slightly compressed tube sound without interferences and unpleasant coloration.

Spring Tank:
The deep and voluminously reverb effect comes out of a high quality six-spring reverb tank (three double-springs) made by the spring reverb pioneer ACCUTRONICS.

Equalizer:
We've chosen three very usable frequencies which makes it easy to form the reverb effect as you like without much efforts.

Balanced In- and Output:
Beside the unbalanced instrumental- / line in- and outputs we've implemented a transformer-balanced input and output as well. It's not that kind of feature that's integrated just to have it, but with great attention towards sound quality. The audio transformers are made upon our specifications to perfectly fit for their purpose.

True Bypass:
There's a true bypass as well as the EFFECT STOP function. The latter allows refining the input signal by the tube preamp without reverberation.

The ReTubeVerb relies on traditional technology but also makes spring reverberation a cutting edge topic.

Notes: Finally the VSR 3.2 is here! It is the enhanced successor of the Vermona VSR-3 - Vintage Spring Reverb.

Most of the features, like the AccuBell spring tank (type 9), the TONE control as well as in and output stages are equal.

What has been improved is the way EFFECT STOP is working. Compared to its predecessor VSR 3.2 offers the possibility to determine where EFFECT STOP cuts the signal path: PRE or POST the spring tank. In the new PRE mode the input of the spring tank is cut from the signal path, so the reverb's decay isn't abruptly stopped when pressing EFFECT STOP and still can fade out.

The VSR 3.2 is suitable for all kinds of input signals like synthesizer, organs, guitars, vocals etc. It's available as of now from stock. It is already listed in our latest price list from 2015-05-01.

*UK 3-pin power adapter included.
