The components used, low-noise conductive plastic controls with minimal channel tolerance, and low-
tolerance polypropylene capacitors, in conjunction with the latest optimized tube stage advance the
sound properties of the classic tone control to an unprecedented level. Precise adjustment allows for
tonal corrections in the bass or treble ranges. Corrections are equally helpful in old muffled and bass-
weak analog recordings and in new digital productions, which sometimes feature a distinct high
frequency tending towards sharpness. Here, corrections of 3 dB truly work wonders.

Control characteristics of the tone control
The control range encompasses the area between the red and blue graphs. The precisely adjustable
controls allow for settings in the 1 dB range based on the scale. One scale mark corresponds to +/-
3 dB.
