Hey guys, I am new to the site so I guess this is my hello message! 
I have played 6 string electric guitar for 5 years, and I have now decided to try out bass. I have been practicing for the past little bit on my girlfriends crap-bass
and I have decided it is time to buy a new one.
My main style will be metal (not death metal or down tuned at all), but this will not be the only thing I will do. I want to venture into other styles and techniques (slap bass for instance) a well. So here I am, with no knowledge of which brands make good bass guitars. I have been searching all over for reviews, but reviews arn't cutting it. Each guitar seems like it is "great". So now I need some opinions.
I'll get right to it. I have been looking at ESP/LTD basses mostly. I like the look, and the "reviews" say the sound is decent. I plan on getting a 4 string bass.
I have been looking at the following:
F-154DX [Invalid or Expired Link Removed]
B-154DX [Invalid or Expired Link Removed]
Now both of those bass don't have active pickups, and I prefer an active sound so I am not too sure. I haven't had the chance to play these yet. A thin neck is also preferred.
I know there are ESP/LTD haters and lovers here (I did some searches), so if you like them, give me a reason why those would be good bass guitars for the price. If you hate it, give me another brand and link (please) to a guitar that would be better for the price. Please keep it under 550CND (around 450USD).
Thanks a lot guys!
*EDIT* And for an amp, I was looking at either the Fender Rumble 100 or 60. Those good? I played through one before just wondering if they are good for the money.
