Seymour Duncan Invader Active Mount – Bridge – Black
The Invader is designed for relentlessly heavy tone. Its overwound coils, three large ceramic magnets, and expansive pole pieces push a thick low end while keeping note definition. It is best for players who want maximum output with a tight, aggressive edge for downtuned or downtuned-like tunings on a 7-string. The neck pickup in the Invader family is described as warm and smooth, providing contrast to the bridge’s brutal output.
Best for: players who need an ultra-high-output bridge pickup to drive heavy riffs and downtuned passages without losing string clarity. Good as a themed sound for drop tunings where crunch and sustain are crucial.
Limitations: As an active system, it consumes more battery management and can require careful installation to preserve balance with the neck pickup.
Wilkinson WOHB7 Classical Ceramic 7-String Humbucker
This 7-string neck/bridge pickup set uses ceramic magnets for a brighter, articulate character with stronger high-end presence. Its open-style humbucker design fits many 7-string electrics and is wax-potted to reduce microphonic feedback. It’s a practical choice for players seeking straightforward hot pickups with clean, defined highs and a strong midsection for rock and metal.
Best for: players who want a brighter, more open tone with firm note definition, especially in bridge and neck positions on modern 7-strings.
Caution: As a ceramic-based design, it may feel a tad brighter or more aggressive compared with Alnico-based options.
Myles Music Shop 4 String Soapbar Alnico 5 (DMM-4)
Although marketed for a 4-string bass, this Alnico 5 soapbar instrument shows the tonal flexibility of Alnico-based soapbars. The 9.5mm Alnico 5 rod magnet provides clarity and a strong fundamental. With 14.5K resistance and 7.1H inductance, it promises a robust, consistent output for versatile electric bass contexts or for experimenting with extended-range guitar setups. It is best for players seeking a punchy, articulate response with smooth mids.
Best for: players exploring Alnico warmth and clarity in soapbar formats, including non-standard guitar applications where a clean, powerful signal is desired.
Limitation: Confirm compatibility with guitar electronics and dimensions before installation, as it’s marketed more for bass parts than typical guitar soapbars.
Artec ASA90 Alnico 5 P90 Soapbar (Neck)
The ASA90 uses Alnico 5 magnets and a P90-inspired voice within a soapbar footprint. It’s designed for neck positions but can also be used in other open-humbucker configurations. Expect bright, present mids with strong articulation and better hum rejection than standard single-coil designs. The 48mm polepiece spacing fits many conventional soapbar routes.
Best for: players seeking a bright, punchy neck-tone with strong midrange and single-coil-like clarity in a soapbar format, suitable for blues, jazz, and rock tones.
Limitation: P90-inspired tone can introduce more hum than some humbucker formats if not well shielded in the guitar’s electronics.
Vintage P90 Soapbar 6.9K/7.2K (Neck/Bridge)
This pair delivers a traditional P90 voice in a soapbar format, with neck at 6.9K and bridge at 7.2K. It provides classic P90 texture—bright, punchy mids with a touch of rasp. The soapbar shape makes installation straightforward for late-era guitars that use P90-compatible cavities.
Best for: players chasing classic P90 textures across neck and bridge with balanced dual-resistance values, suitable for blues, rock, and vintage-inspired tones.
Limitation: P90-style tone can introduce hum in noisier environments if shielding is not optimized.
Vintage P90 Bridge Alnico 5 Soapbar
This bridge-oriented P90 soapbar mirrors the neck model’s tonal goals with a focus on higher-output bridge performance. It emphasizes the classic P90 bite and midrange presence while maintaining compatibility with standard guitar cavities designed for soapbars.
Best for: players who want a consistent P90 voice across neck and bridge to preserve midrange character with improved output in the bridge position.
Limitation: Bridge P90s may require careful height adjustment to balance with the neck pickup for even response.
Buying Guide: Key Considerations For 7-String Soapbar Pickups
- Magnet type: Alnico 5 delivers warm, musical highs and clear mids; ceramic magnets offer brighter, more aggressive tones with higher output. Choose based on whether you want vintage warmth or modern bite.
- Rough output and resistance: Higher resistance typically provides thicker tone and more sustain, especially on the bridge position. Check neck vs. bridge specs to balance the overall guitar sound.
- Single-coil vs humbucker behavior: Soapbar formats can be hum-canceling like humbuckers or retain single-coil brightness. Consider your noise environment and wiggle room for shielding.
- Compatibility: Ensure the pickup’s physical dimensions and mounting style fit your 7-string guitar’s cavity routing and wiring harness.
- Intended position: Bridge pickups generally push more aggressive lows and highs; neck pickups emphasize warmth and clarity. Some sets are designed specifically for neck/bridge coexistence.
- Active vs passive: Active systems (like the Invader) require battery power and can offer very high output with tight bass; passive sets preserve dynamic sensitivity and easier power management.
- Wiring options: Some pickups offer coil-splitting with four-conductor wiring, which can expand tonal options but adds installation complexity.
Frequently Asked Questions
- What is a soapbar pickup?
A soapbar pickup is a rectangular, shielded pickup that fits in standard guitar cavities and provides a balanced envelope of tone, often in humbucker-like configurations. - Are P90 soapbars suitable for 7-string guitars?
Yes, P90-style soapbars can fit many 7-string guitars, offering bright midrange and single-coil-like attack with hum-canceling designs in some models. - Which pickup is best for downtuned metal?
High-output bridge pickups with ceramic magnets or active designs, like certain Invader-style models, tend to sustain tight low-end and aggressive high-end, suitable for downtuned styles. - Do Alnico soapbars sound different from ceramic ones?
Yes. Alnico tends to be warmer with smoother highs, while ceramic magnets typically deliver brighter, more aggressive attack and higher output. - Can I mix neck and bridge pickup types?
Yes. Mixing Alnico and ceramic or different output levels can produce a diverse range of tones, but ensure proper balance and installation compatibility. - Is shielding important with soapbars?
Shielding helps reduce hum, especially with P90-inspired or single-coil-like voices, and improves overall noise performance in live settings.
