Update.
I received the pickup last week, though I have been out of town at that time, so I installed it yesterday and tried it a couple of minutes ago.
Overall the pickup is middy as hell, though the bass is very tight and strong too. Highs are more icepicky than I imagined, but in the end it complements the guitar well.
I will have to give it a couple of weeks to try it out righteous - with the band situation etc etc.
On the first "hearing" - I find mids too strong, maybe a bit too hard to dial out - since they carry alot of highmid content too - so while having "heaviness" to the sound, it never gets muddy. A plus on that one though! I'm already loving the "icepicky" highs, since now finally my high strings sound tight and pronounced, and switching from the previously installed pickup - I found no problems with dynamics, they are still there. As with the previous bridge pickup - I prefer the pickup as close to strings possible (at least on the bass side). Output of the Supermassive 90 is not hot, maybe a bit hotter than the sock Seymour, and as it is now - is in perfect balance with the neck Seymour - volume wise.
Conclusion:
The guitar sounds grittier now, a bit fatter, much clearer and pronounced, but still sounds like the instrument I know and play for years.
Packaging is great! STICKER!!! Nice touch - I love stickers, and also thanks for the glass, errr... cup coaster? :lol:
I'll probably stick with it since it's certainly not a downgrade from the Seymour, and I like to support small independent guitar/effect/etc businesses!
Punk! :band5:
Thanks,
