Acustica Audio has announced a limited sale on two of its audio effect plugins.

Ruby 2 is an official endorsement and a faithful representation of the D.W. Fearn highly sought-after vacuum tube equalizer VT-5.

The original hardware equalizer uses passive LC circuitry with class-A triode vacuum tube stages for the input and output. The input transformer is made by Jensen. The output stage utilizes the same custom Jensen transformer used on the VT-1/VT-2 mic preamps.

For a limited time you can add Ruby to your setup for just 79 EUR (regular 235 EUR).

The Lemon delay features 40 delay and tape emulations, allowing you to discover the astoundingly organic sound of the best machines ever manufactured.

Its 40 programs are able to faithfully reproduce the behavior and sound of many different hardware delay machines, both vintage and modern. A clever feedback scheme (offering different types of filters for each emulation) and an adjustable drive control gives you the possibility to use Lemon as an effective tape/overdrive simulator as well.

Until February 21st, Lemon is on sale for only 49 EUR (regular 129 EUR).

Both plugins come in VST, AU and AAX formats for Windows and Mac.
