Product details

The EVE-AT4 is a tribute to the EQ section of the Neve 1084, which was created as the successor to the legendary Neve 1073. The EVE-AT4 was designed with simplicity and clarity in mind, allowing for straightforward usage and immediate productivity. Although the EVE-AT4 possesses fewer bands, a smaller frequency selection palette, and less Q bandwidth selection options as compared to the EVE-AT1, its strength lies in its unique filter implementation, producing an idiosyncratic frequency response not present on the EVE-AT1. The result is a particular tonal character; the sound and tonal shape of its original incarnation is a hallmark of many classic recordings from the 70s. Best for sweetening up low frequencies, although mid and high frequencies can benefit as well.

“The AT4 is the more characterful, its strengths being broad 'brushstroke' usage - adding sheen to acoustic guitars and vocals, for example - and general bass boosting.” 9/10, Performance & Value Award. Computer Music Magazine.
