Description

Edit description

Step into the realm of high-end audio manipulation with the Manley Massive Passive Stereo Tube EQ. This two-channel, four-band equalizer is more than just an EQ, it's an artistic tool that helps shape your sound with natural, organic methods. The passive design uses only metal film resistors, film capacitors, and hand-wound inductors to sculpt your sound, much like a Pultec EQ on hyper-steroids.

The Manley Massive Passive is not just a device for tweaking frequencies, it's a creative instrument, built for artists with artistic goals. This EQ is designed for both the most radical EQ needs for tracking and the subtlest shadings for vocals and mastering. With twice as much EQ and half the coloration, Massive Passive delivers incredible high frequency boosts without sibilance problems and an unbelievable fatness without mud. This is EQ creativity at its best, with a few quirks and idiosyncrasies that will spark your audio adventure.

A Rock Box That Loves To Dance

It's not surprising that in this day and age of digital daw's and fancy gui's the need for a piece of kit with character is mandatory. The MP is such a box where if you put anything through it's circuit without even twisting the eq it already sounds good. I used it on vintage drummachines like the 909 and 606. Even a Linndrum that I had on loan. Of course it brings more to the table and gives you loads of oopf, transients and smoothness, but what would you expect from a company where the head honcho (EveAnna Manley) is a bike riding baddass. This eq is the one I'd call if I ever got caught in a bar fight and wanted to make sure I needed to survive it..

One of the best EQs on the market.

One of the best EQs on the market. Warm, analog, precise, with lo-cut and hi-cut filters. Solid made. Good servicable. I use it a lot in recordings, like vocal recording, but it´s also main part when I create my and the systematic sounds sample libraries. In the final process it's also then part in the mastering, especially for the buttom and top end. Also everytime when somethings sounding too clean or too digital.
