On those songs, I believe it's 2 tracks of guitars per side, 4 total. Some songs have 2 tracks per side, others just single tracked per side.
For the singer's voice, there is only compression and a hint of reverb. I used the Rvox compressor and Trueverb plug ins for his tracks and nothing more. I think the biggest part of getting that nice OD type sound is the double tracking we did on the vox. I had him go through each song twice at a minimum and blended each take. Usually I'd have him keep the structure the same but vary his screams to add thickness. In some parts of songs, for some extra emphasis, he'd go complete opposites on the tracks - say, one high pitched scream and another really low. Blended together, we dug it.
There is usually another "back up" vocal going as well at different parts but not all the time. I don't think we used them too much on these 2 songs, but here and there you can pick them out. For the backup vocal tracks, I used the Rvox compressor plugin and the Waves pitch shift plug, can't remember the name, I have 2. I used one of those and shifted the vox down about 5%. On 1 or maybe 2 of our songs, I also used an Ozone preset called "bad phone" or something like that. But, that effect is not on either of the Myspace songs.
In all, we did 5 full band tracks and 3 instrumental "mood" pieces to break up the EP and give it cohesiveness. I wrote 2 of the pieces and our bass player wrote a 3rd. Within those, I wrote some orchestral parts and played them on a synth to add some eerie moods - strings, operatic voices and such so all 3 pieces are in the same key and have the same thematic elements. I'm probably most proud of those, lol. I'm not a keyboard player much, so I had to track each "Instrument" from the synth individually as I wrote the "orchestration", but I think they came out great. I need to post one of those. As far as something that pushed my limits, I'd say those pieces were the hardest for me to do aside from the recording. They were just so different from what we do as a band. I'm excited to get this EP out, so far the reaction has been really good.
