Welcome to V13 KlangFormer

A software plug-in, matched with the frequency response of V13, that
offers a useful and high-graded selection of different colorations.


The WeissKlang V13 distinguishes itself through a linear frequency response which is very suitable for the post-processing.

In close collaboration with Sonimus we created a powerful plug-in

- the V13 KlangFormer.

It provides you 5 high-quality colorations, ranging from old tubes with beautiful harmonic distortions to modern transformers and warm ribbon microphones  


Unlock your V13 and get the best sounds, right at the palm of your hands. 

For the best experience we recommend preamplifiers with
a linear frequency response, which can be found in most audio interfaces.




Delivers a sweet and airy high frequency response, rich mids and lows, providing the iron sound of transformers.

The signal therefore sits perfectly in the mix. It’s magical on vocals and acoustic instruments.


Offers the famous mid-forward sound of the old days with strong mids, well-balanced lows and focused high frequencies, which had a significant impact on recordings of the 50s and 60s.


Sounds outstandingly musical with natural highs, tight mids and a warm low frequency response by merging the best acoustic properties of FETs and transformers.

This mode is excellent for a variety of sources.


Reproduces the warm sound of old triode tubes with silky highs and full lows. It also increases harmonic distortion and makes the signal larger than life.

For this versatile mode, there are countless applications.


Provides the characteristic sound of ribbon microphones with balanced mids and slightly deemphasized highs combined with a smooth low end response. It sounds great on vocals, but
also on guitars, horns and pianos.
