Ugh, these "vs." threads...
Fact: Paul wrote a huge chunk, if not all of AEnima and Justin pretty much just recorded what you hear on Aenima. Some lines sound like his style, some don't.
I'm sure that if Paul had stuck around (he left because he wanted to do other things and the rest of Tool weren't cool with that at the time) the music would be the same.
I honestly don't think you can compare the two guys cause Paul's best playing is only on one album, Undertow. With Justin we have three... kind of an unfair match up, if you ask me.
However if you take the best playing from both bassists, Undertow with Paul and 10k Days with Justin. I think these guy's have pretty similar styles of writing/playing. Hell, Justins tone on 10K Days is very much like Pauls on Undertows, and I'm sure JC got some inspiration from Paul's playing on Undertow and some of Opiate.
Check out Justin's playing on Peaches "Giving Birth to a Stone" to hear him pre-Tool, playing his Stingray.
I don't prefer either players playing.to each others. Tone, though...
Paul had
THE pissed off bass tone. Can't possibly sound any meaner without adding a distortion of some sort. On top of that, it's clear.
As far as tone goes, I prefer Pauls. I LOVE Justins though, I jsut like Pauls rawness.
And to Chris2112, Justin doesn't have effects on all the time and his Wal is never bogged down by them...
He actually has a "clean" tone 90% of the time. He runs the dual channel dirty/clean thing all the time so the distorted channel (via Pro Co Rat and Boss EQ) really doesn't count as an effect.
