The instrument produces bold, rich organ sounds and has a wide range of tonal variations (13). The Panthers 16', 8', 4' Stops and Mixture voice levels are adjustable. Each note spans over three octaves, there is bass extension into grey keys and separate volume control for bass octave(s).


Tone Decay adds percussive effect to Mixture voices. The Panther has powerful vibrato with speed and intensity control.


The Elka Panther is also available as part of the Retro Pack, a collection of Martinic's grooviest instruments and effects with a bundle discount.



Available as early as 1966, the Elka Panther was designed to have it all. Tweakable and versatile, families of sound would be activated using plastic switches – the on/off equivalent of pulling out stops on an organ. The switches controlled which family of sounds were activated, and were laid out horizontally in order of their pitch.
