Frequently asked questions
Which is better for djent and metal?
Both are engineered for metal and djent. The Rails deliver pure aggressive output without batteries; the MortalCoil offers the same metal voice plus two alternatives if you want to explore other tones without switching pickups.
Do I need to modify my guitar for either set?
The Rails fit standard 7-string cavities without modification. The MortalCoil is advertised as drop-in compatible with existing active setups and includes installation hardware, but your guitar must already have routing for active electronics.
What's the main tone difference?
The Rails use Alnico 8 magnets in a passive design for tight, controlled midrange articulation. The MortalCoil uses high-density copper coils with an active preamp that adapts across three voices while rejecting noise—offering more tonal range from one set.
Which requires more maintenance?
The passive Rails require no battery changes or circuit maintenance. The MortalCoil uses active circuitry and a battery, so it demands periodic battery replacement during heavy use.
