The TRIBUTE volume control is an inductive control, which means that unlike "normal" volume controls (which use some sort of resistive element) an inductive element is used.
The main advantage of using an inductive element is the low DC resistance of the windings.
A standard resistive volume control is 10k, 50k or 100k. The Tribute inductive volume control has a DC resistance of only 33 ohms, which results in a more transparent and dynamic sound, especially at low volume settings.
The AC resistance can be calculated and is frequency dependent. The Tribute volume control has an AC resistance of about 20k at 20Hz and 1Mohm at 1kHz.
Most inductive volume controls are wound as transformers with primary and secondary windings.
In contrast, to reach the ultimate in dynamics, bandwidth and transparency, the Tribute volume control is wound as an autotransformer, which means that a single, tapped coil is used.
The pictures show that the volume control is a complete stereo control by mounting the coils on a 24 positions ELMA switch, also to keep connections as short as possible.

Mono controls are also available.
