The sound is very smooth with a big, but well defined, low-end. The output level control allows to change the characteristic of Fredenstein F609 500-Series Tube Preamp and to run the first stages all the way up to distortion. As all Fredenstein products, Fredenstein F609 500-Series Tube Preamp is designed by a German-American team and manufactured in Taiwan.
