Ignite Amps PTEq-X

Ignite Amps, a company born from the desire of two musicians to simply build what they need and avoid “pre-packaged” products, has released PTEq-X, a digital emulation of the classic Pultec PEQ1A, MEQ-5, and HLF-3C passive equalizers. PTEq-X has been developed to have all the characteristics of the original hardware, plus some circuit improvements and additional features to increase its versatility. Every single component on the signal path of the real analog circuits has been modeled to match the original sound, keeping an eye on CPU performance and real-time playability. Best of all? Ignite Amps PTEq-X is available now, for free. It requires OS X 10.6 or later and an AU or VST plugin host.
