Vintage Tube Amplifiers and Custom-Designed Transformers set the soundstage. True Passive Equalization creates Bountiful and Musical Equalization curves. The new RETRO 2A3 is designed as an ultra High-Fidelity Program Equalizer whose sonic benefits go beyond the equalization process. Accurate to the industry-standard Pultec EQ performance, the RETRO 2A3 adds HF boost frequencies in several new sweet spots. Carefully implemented HF boost circuits capture the signature sound of the original passive equalizers. Use these settings to make individual tracks fit in place. Make a vocal shine and add distinct presence. There are many satisfying applications, most notably the stereo mix buss.

"The Retro 2A3 has become my new ‘go to’ on kick. Clean and open but big with lots of character. Everything Retro makes is just quality tone.”
Joe Chiccarelli

“It took me a little while to really get to know the EQ and what it is capable of and the results are beautiful - I am out of my mind in love with my 2A3 on the mix buss.”
Paul Leary
Producer & Musician
"The 2A3 eq is just stunning. I have been loving taking one side and sending it into the other side; creamy, juicy and sweet on the bass. The combo side of the Sta-Level and the 2A3 on bass is unbeatable. Retro Instruments has created an instant winner."
