What is the difference between the neck and bridge pickups in this set?

The neck pickup (RA-350C) operates at 3.12 kHz with 4.25V single-string output, delivering brighter articulation, while the bridge pickup (RA-370C) sits at 2.33 kHz with 4.0V output for tighter lows and focused punch. Both maintain the same 3.1 kΩ impedance and low noise floor, ensuring balanced responsiveness across the full seven-string range.

How long does the battery last, and can I run higher voltage?

A single 9V battery provides approximately 715 hours of playing time. The active circuit supports up to 27V DC maximum, so you can run stacked batteries for extended headroom and sustain if desired—the circuit will adapt automatically.

Is this set suitable for blues or jazz playing?

No. The Super 77-7 is voiced for metal, djent, progressive, and extended-range styles. Its high output, tight low end, and active noise floor are optimized for high-gain clarity; it is not designed for blues or jazz applications.

What is included in the set, and do I need any additional wiring?

The set includes both pickups, two 25K volume potentiometers, two 25K tone potentiometers, a battery bus, and a stereo output jack with solderless plug-and-play connectivity. No soldering is required for installation.

What noise floor does this pickup set maintain?

The neck pickup achieves -98 dB at 60 Hz and the bridge pickup -96 dB, providing ultra-low noise for clean signal integrity even at extreme gain levels.

Do I pay sales tax on this order?

We collect sales tax only on orders shipped to California. Orders shipped to any other US state are charged $0 sales tax at checkout when you buy direct from our website. On this item that is roughly $16 less out the door than the same listed price at a national retailer or on a marketplace. Marketplaces such as eBay, Reverb and Amazon collect sales tax in nearly every state as marketplace facilitators no matter who the seller is, so the same item at the same price costs less bought direct. Free US shipping and 30-day returns are included. Some states ask buyers to self-report use tax on out-of-state purchases.

EMG Super 77-7 Retro Active Humbucker Pickup Set in Black

The EMG Super 77-7 delivers articulate, responsive active tone with the retro aesthetic of open-coil design. Built for seven-string players, this set pairs a neck-positioned RA-350C with a bridge-positioned RA-370C, engineered to balance clarity and punch across your instrument. The solderless plug-and-play connectivity and included potentiometers make upgrading existing hardware straightforward—no soldering required.

Tone & Output Characteristics

The neck pickup operates at a 3.12 kHz resonant frequency with 4.25V single-string output and 8.0V maximum strum output, while the bridge pickup sits lower at 2.33 kHz with 4.0V and 8.0V respective outputs. Both pickups employ ceramic magnets and maintain 3.1 kΩ output impedance, with noise floors of -98 dB (neck) and -96 dB (bridge) for clean signal integrity across high-gain applications and live settings.

Electronics & Power

The active circuit draws 350 µA at 9V, yielding approximately 715 hours of battery life per charge cycle—enough longevity for serious touring. Maximum supply voltage reaches 27V DC, permitting either single 9V or stacked multi-battery configurations for extended headroom and sustain on stage.
