What's the difference between the EMG 81-7H and passive 7-string pickups?

The 81-7H is an active pickup powered by a 9V battery, delivering consistent 1.75V peak output and low noise (-91 dBV) without losing clarity on extended lower strings. Passive pickups rely on string vibration alone and typically produce lower output and more noise, especially on a crowded seven-string mix. Active circuits also provide the aggressive upper-mid presence and controlled low-end that define modern metal tone.

Do I need to solder this pickup to my guitar?

No. The EMG 81-7H uses EMG's solderless wiring system and includes volume and tone potentiometers, output jack, battery clip, and all necessary cables. You connect the pre-wired components via push-connectors and mount the battery clip inside the guitar body.

How long does the 9V battery last?

The battery provides approximately 1500 hours of playable life when paired with another pickup in your guitar. Current draw is minimal at just 80 microamps, so the battery lasts weeks to months depending on how often you play.

Is this pickup suitable for both bridge and neck positions?

The 81-7H is optimized for bridge-position installation but can also work in the neck position. Many players use it in the bridge for maximum aggression and output, where its articulate character and upper-mid peak shine on leads and rhythm work.

What genres does the EMG 81-7H work best for?

This pickup is engineered for metal, djent, progressive, and high-gain applications where string definition and output consistency are critical. Its aggressive upper-mid presence and controlled low-end make it less suited to jazz, blues, and folk styles that rely on warmth and sustain.

Do I pay sales tax on this order?

EMG 81-7H Long Shaft 7-String Active Humbucker Pickup in Black

The EMG 81-7H is a high-output active humbucker engineered for seven-string instruments, delivering focused, articulate response across extended lower ranges. This ceramic-magnet design pairs aggressive upper-mid presence with controlled low-end, making it ideal for bridge-position recording and tracking in extended-range guitars. The solderless wiring system and included potentiometers streamline installation for studios ready to swap in a proven workhorse that captures definition across all seven strings.

Tone & Recording Clarity

The 81-7H produces a peak output of 1.75V with 1.25V RMS, cutting through the mix with minimal noise at -91 dBV. Its 2.25 kHz resonant frequency emphasizes clarity and articulation, ideal for modern metal and high-gain tracking where string definition and separation matter on all seven strings—ensuring each voice sits clearly in the session without muddiness.

Power & Installation

This active pickup runs on a single 9V battery with approximately 1500 hours of battery life when paired with another pickup, and draws just 80 microamps at 9V for efficient, stable power during long recording sessions. The solderless installation system includes volume and tone potentiometers, output jack, battery clip, and all necessary cables—no soldering required for a clean retrofit into your tracking rig.
