I've been trying to figure out these bass sounds but I'm stuck.

Here's the first one:

To me it sounds like a sine bass mixed with a real one.

Here's the other:

This one sounds like a real bass with tons of reverb.

 

Nice songs. I had never heard of them before but you could find some info looking up studio sessions like this one for Thrice on youtube there are a couple studio vids.

 

The 1st one sounds like just a synth to me, no guitar. But I have a pedal that makes my bass guitar sound like a synth, so Wwho knows except the engineer, producer and artist. The 2nd one sounds like a real bass with reverb played high up the neck or chimes until about 3.20. That sounds like a synth, but again, hard to say. So many ways to process a synth to make it asound like a guitar--and so many ways to process a guitar and make it sound like a synth.

 

Thanks, I saw that vid. Unfortunately doesn't go too deep into the production.

In the 2nd track, the bass lines after 3:20 just sound like a real bass to me. The attack makes me lean that way. But, it could very well be a synth.

 

From Wikidpedia. Possibly search each engineer and might be some tips?
