Available for download, the Softube Tube-Tech MK II EQ Collection bundles together two plug-ins, each modeled on classic Tube-Tech equalizers and each sporting sonic and graphic improvements over their corresponding original versions. Both of the hardware inspirations for these plug-ins were themselves modeled on hallowed Pultec equalizers. The software EQs have been housed in a single plug-in for your convenience.
First you're given the PE 1C, a passive, tube-driven equalizer suitable for many different sources such as drums, bass, guitars, and vocals. The EQ features a low-frequency section made up of two low-shelf filters that can be combined to attenuate and boost at the same time, resulting in unique filter curves and resonances. The high-frequency section has a peak and a shelving filter working in parallel, which can help you secure a smooth top end that doesn't become overbearing.
Next you have the ME 1B, a three-band mid-range EQ based on Tube-Tech's recreation of the Pultec MEQ-5 equalizer. The hardware ME 1B is tube-based equalizer designed to accompany the PE 1C while providing control over the frequencies that the PE 1C cannot adjust.
The ME 1B provides a low-frequency boost a large-range (200 Hz to 1 kHz) a sweepable cut (200 Hz to 7 kHz), and a high-midrange frequency boost (1.5 to 5 kHz). The mid section never boosts, but always attenuates the selected frequency. The low and high bands always boost their corresponding frequencies.
On their own, both modules are suitable tools for tonal shaping. Taken together, they comprise a versatile and full-featured equalizer. These plug-ins are available for Mac and Windows platforms, and include the legacy MK I versions.
