A 500 series EQ that delivers it all, control and electric tone, you won't believe what it can do for your music!

Ordering in pairs? We can usually ship sequentially numbered units!

The Electra, or Electrified Transient Equalizer, is a 4-band, multi-topology eq designed to precisely and musically redefine how the transients and harmonic energy of a sound interrelate, opening up completely new creative possibilities for how sounds interlock, move air, and impact the emotions. The tone of this box is quite literally electric, with a crackling but incredibly smooth and detailed midrange, tightly defined low end, and unmistakably analog high frequencies.

The heart of the Electra is two fully sweepable Proportional-Q bands tailored to allow for extreme pushes without sounding stressed or unnatural. The more you boost or cut, the narrower these filters get, which makes them gentle at low gain and powerful at high gain. Their adaptively musical shape allows you to add a tight 'thwack' to snares, brighten a vocal without sacrificing warmth, or even completely rebalance the elements within a drum loop as if you had faders for the various elements.

Rounding out the bottom is a fixed low shelf which pairs beautifully with the the continuously variable (25-400Hz) 12db/octave HPF. The HPF has just a touch of bite on the corner which makes it rewarding to clean up the mud; the shelf and HPF combined allow you to reshape, de-clutter, and tighten up even the most unruly low end.

Topping it all off is a sparkling, fully sweepable (3.4-20k) high shelf reminiscent of the coveted vintage mastering EQ’s of yore; it'll give life to the darkest, murkiest sound, and adds a smooth top end that plugins simply cannot replicate. Ribbons, overheads, vocals... anything that needs shimmer will love the treatment this filter gives.

The Electra is analog at its finest, and represents Kush's ongoing commitment to pushing the envelope and creating processors that fuel the creative and artistic aspects of mix engineering and music production.
