Thanks for the welcomes!
Yes, the seller recommended new pickups. I'm sure it helps to know what kind of music I play as well. I would say the seven-string allows me to play harmony / melody combinations, which I feel is my current weakness. I want to play things with larger scales, and branch into interpretation of classical music. I'm also heavily into Mushroomhead, and I was getting bored of downtuning my six-strings to BEADGB.
I think perhaps the Universe is excessive for my second 7-string, you're right. I'm going to take a stab at guessing that it requires a lot of getting used to (wider neck, more ranges available to you) so I need to break it in a little. That was another of the questions I had; is it almost like learning a new instrument?
