Mercury EQ-P2

Design & Build Quality

Mercury EQ-P2

This unit screams vintage elegance. Its design stays true to the original Pultec vibe, featuring a sturdy metal chassis and classic knobs that are both smooth to operate and incredibly tactile. The Mercury EQ-P2 is handcrafted with meticulous attention to detail, ensuring durability and top-notch performance. Plus, the all-tube circuitry adds a warm glow — literally and figuratively — to your studio.

Tube-Tech HLT-20

In contrast, the HLT-20 blends retro aesthetics with a modern twist. Its bold blue faceplate is iconic, and the layout is intuitive for quick adjustments. While it’s built like a tank, the HLT-20 is slightly lighter and more compact than the Mercury, making it a tad more rack-friendly if space is tight.

Verdict: If you’re after timeless charm, the Mercury EQ-P2 takes the crown. But for practicality and modern aesthetics, the HLT-20 edges ahead.

Sound Quality & Tone

Mercury EQ-P2

The Mercury EQ-P2 is a master at delivering that lush, buttery sound audiophiles crave. Its broad EQ curves are incredibly musical, making it perfect for sweetening tracks without harshness. Whether you’re adding air to vocals or giving a bassline some heft, the EQ-P2 excels. However, its vintage-inspired design means it’s not as precise as modern EQs.

Tube-Tech HLT-20

On the flip side, the HLT-20 offers more surgical precision. Its tilt filter is a game-changer for balancing frequency spectrums, and the shelving EQs are exceptionally clean. While it doesn’t have the same “vintage mojo” as the Mercury, it’s versatile enough to handle everything from subtle tweaks to bold tonal shifts.

Verdict: The Mercury EQ-P2 wins for warmth and musicality, while the HLT-20 shines in precision and flexibility.
