Klark-Teknik DN-50 Dual Reverberation System Spring Reverb

Made in the late 70, Klark-Teknik DN-50 is a dual-channel analog spring reverberation system.

At the core of the unit are 6 springs that produce a vintage-flavoured reverberation great for guitars, vocals and much more.

The controls are quite advanced and make this unit very versatile. Each channel has an input and output trim, dry/wet mixer and a two band shelf EQ.
