EVE-AT4 is a 3-band equalizer with an additional high-pass and low-pass filter. Designed as a tribute to the EQ section of the Neve* 1084, which was created as the successor to the legendary Neve* 1073. 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. Both the AT1 and AT4 were designed with simplicity and clarity in mind, allowing for straightforward usage and immediate productivity. Although they share certain tonal characteristics, the EVE-AT1 and EVE-AT4 reveal their differences in the details. The EVE-AT4 is the stronger ‘character’ equalizer, while the EVE-AT1 is suitable as a ‘go-to’ equalizer for a wide range of instruments and musical applications.
