Manley Massive Passive Equalizer

The MASSIVE PASSIVE is a two channel, four band equalizer, with additional high pass and low pass filters. "Passive" refers to the tone shaping part of this clever new EQ design - not using any active circuitry, only metal film resistors, film capacitors and hand-wound inductors sculpt the sound.
Super-beefy, hugely-high-headroom Manley all-tube make-up gain amplifiers deliver your tunes into the next realm.
