Hi guys. I'm not really familiar with Spectors but from what I've read so far in this board, they're of exceptional value. I play all kinds of rock music..rock n roll, punk, alternative, grunge, etc. and I like to have a deep and thumpy tone. I was wondering between the Spector NS2000/4 and Spector Rex4, which is the more suitable. Secondly, what are the B strings like for the Rex5 and the NS2000/5? Any help will be very much appreciated. Cheers guys.
