Re: Need help with invader....
The one that's designed for the neck is going to sound a lot better, trust me. Pickup sets (i.e., Invader bridge/Invader neck, 59 bridge/59 neck, etc.) are calibrated to adjust for the different amplitudes (width/distance) of the string vibration close to the bridge vs. close to the neck.
A string's vibration pattern is much more narrow close to the bridge, meaning there is less energy there to fluctuate the magnetic field, meaning it creates a weaker signal. So bridge pickups are wound "hotter" (more turns of copper wire coil) to compensate for this weaker signal (and to add midrange and bass) and effectively amplify it so its output will balance better with that of the neck pickup.
Hence, the Invader bridge (16.8k) is wound much hotter than the Invader neck (7.2k). There are SOME bridge models of some of Seymour's pickups that can conceivably work well in the neck position, like the Alnico 2 Pro bridge (7.85k vs. 7.6k neck), Jazz bridge (7.9k vs. 7.72k neck) and even the Seth Lover (8.1k vs. 7.2k neck). This is because they are all around the 8k mark and below, which is a good rule of thumb where neck pickups should be in terms of DC resistance.
Because the string over the neck position has that wider amplitude of vibration, you get a LOT more bass frequencies out of your neck pickup, which is why neck pickups sound round and fat. So if you put a super-bass-heavy pickup like the Invader bridge model in the neck position, you will regret it. Not only will it sound super-mega-muddy, it will be MUCH louder than ANY pickup -- including another identical Invader bridge model -- in the bridge position.
Your friend probably put his neck model Invader in the bridge position, which would explain why it sound so "bright".
