Manufacturer Description:

The DSR-3 - dual spring reverb - is a professional spring reverberation
unit for use with stereophonic sound sources. Besides this function, the
unit offers additional parallel and serial operational modes for
advanced and creative applications.

As in our valve based model ReTubeVerb, the classic VSR-3 and the
creative Retroverb Lancet, the DSR-3 relies on finest quality
reverberation springs manufactured by AccuBell (formerly Accutronics).
To assure perfect stereo sound, the springs were carefully selected and

Each channel offers two band equalization with BASS and TREBLE control
being matched to the specific frequency spectrum of the springs. By
this, the effect can easily be adapted to your personal sound

The DSR-3 offers TS in- and output jacks as well as balanced XLR in- and
outputs. Balancing the outputs is carried out by specially designed and
manufactured output transformers with excellent sound characteristics.
This also qualifies the unit to be used as a first class DI box.

The three operational modes allow both SPRING REVERB channels to be used in interaction or independently:

STEREO for the use with stereophonic sound sources. For perfect
channel matching, the first SPRING REVERB channel's physical controls
are used to define both channels settings.

DUAL MONO for use with two independent sound sources. Each DSR–3 channel works as an independent unit.

SERIAL for experimental reverberation effects. Here, the first
SPRING REVERB channel is fed into the second channel. This allows
creation of long lasting reverberation tails.

The DSR-3 is carefully assembled by hand in our electro acoustic manufactory in Erlbach, Germany.

The VERMONA DSR-3 allows creating full, deep and rich reverberation
effects at highest quality breathing the charm of former days.
