Re: Invader or JB
Blink182 used an invader for everything apart from the last album.
Greenday used a JB for everything apart form the last album. (i think)
I use an invader and my bandmate uses a JB, both very cool pickups but also VERY different sounding. The invader has huge amounts of meaty bass, a really big sound, its as thick as they come, i love it, but many others find it overkill, in certain woods like a thick mahogany body its not suited, but in a squire it should be fine. The JB is probably more versatile, and also cleans up quite nicely, its no-where near as thick as the invader, but has similar output.
Both pickups are great and would be well suited to your music, i'd get the one which you think is more liek the sound you want, and use the 21 day exchange to get the other one if you are not 100% satisfied.
BTW, there is VERY little flaming on this forum, and there are a fair few people who do appreciate blink and greenday here, and also some that have produced great guitars from squiers, so i wouldnt worry about asking questions.
