Thanks fellows!
Beep - I do have a Squier bass here, equipped w/ flat wounds, so I could technically record a proper bass track. I was just so focused on wrapping up everything as quickly as possible that I did not bother.
You know, the funny thing is that the guitar that works best for the kind of stuff is the good old Epiphone Les Paul Standard. I do have a Traditional, with "better" pick ups (or at least, they have better definition) but the Standard has a certain type of mids that just fit the bill better than anything else.
I've been wanting a Gretsch for the longest time, but in the absence of it, I now know that that LP is the best tool I have at my disposition.
The Gibson SG has even "better" pick ups, and that guitar just cuts through a mix like nothing else, but I couldn't lay proper foundation for this type of track with it. So it was LP Standard for the most part, overdubbed w/ the SG for some more clarity.
The Riviera (ES-type) was actually only used as an afterthought, for the big Em drenched in reverb because I needed the Bigsby to do that cliché type of thing.
The real reason behind this is that I needed to cover up for the other guitars in the chorus which were cut a bit short before the second verse. And I was so focused on finishing the cut that I didn't want to re-track - I envisioned it as an engineer who's left with the tracks as is and needs to make something out of it. So I plugged the Riviera and recorded that one chord.
It's kind of cheesy so I thought it was okay for it to really stand out rather than try to blend in.
Julien - Yeah, I guess eventually I would need a big old Fender, at least for this type of stuff. But that's only part of what I do - trust me, the Marshall will get plenty of use here. We also want to do something that's more metal oriented, and I have my own other projects.
