Bring the holy grail of tube equalization into your studio. Hand-built in Chile with obsessive attention to detail, the Stam Audio SA-EQP1 (also referenced as the EQPM-1A series) is a no-compromise replica of the legendary Pultec EQP-1A, but with a massive bonus: it also includes the coveted mid-band section of the Pultec MEQ-5.

Whether you are looking to do the famous "Pultec low-end trick" on a kick drum, add silky 10kHz+ air to a lead vocal, or carve out muddy lower-mids with the MEQ-5 section, this unit delivers that larger-than-life, finished record sound. Simply running audio through its tubes and transformers without turning a single EQ knob adds an incredible 3D depth and analog weight to your tracks.

Why This Equalizer Stands Out Unlike budget clones that cut corners on the most important components, Stam utilizes an authentic three-transformer configuration (input, interstage, and output) to perfectly capture the massive low-end and smooth highs of the vintage units. Additionally, the fusion of the EQP-1A and MEQ-5 circuits into a single 2U chassis makes this an absolute powerhouse for both tracking and mixing.

Key Features

• Two Classic EQs in One: Features the full high/low boost and cut functionality of the EQP-1A, seamlessly integrated with the crucial mid-band cut/boost section of the MEQ-5.
• Premium Iron: Equipped with premium custom Sowter UK and/or custom US-made transformers (depending on exact batch), ensuring absolute historical accuracy in frequency response and analog coloration.
• High-End Inductors & Caps: Built with authentic Carnhill and/or Cinemag inductors, alongside premium Vishay/WIMA capacitors to guarantee those sweet, musical EQ curves.
• All-Tube Makeup Gain: Fully discrete Class-A circuit utilizing 12AX7 and 12AU7 tubes for the audio path, plus a 6X4 tube rectifier in the power supply to provide authentic vintage "sag" and harmonics.
• The Famous "Low-End Trick": Allows you to boost and cut the same low frequency simultaneously, creating a tight, massive bottom end that sits perfectly in a mix without getting muddy.

Condition: Very good because of typical rack rash. Included: Stam Audio Equalizer Unit, Standard IEC Power Cable.
