Wow, yeah, that's a lot of stuff in the signal chain.
Here's a big problem with what you described:
"
Mic> Vocal Effects rackmount> BlueTube Pre Amp> Compresser> Limiter > into input 1 on mixer> RCA L/R out to input on RCA L/R in on 8 Track recorder"
The mic always goes into the preamp first. The signal out of the mic is so weak that the effects unit can't do anything sensible with it at excpet make it sound (much) worse. Switch the pre and the effects around and see how it sounds.
I'm not sure what you're recording device has in the way of effects, but usually effects are added during mixing and NOT when you are recording. Unless I know EXACTLY how all the instruments are going to sound at the end and EXACTLY what effects I want on a track, I never record my tracks "wet" (with effects.)
Even if your recorder doesn't have its own effects, there is probably a way to use your mixer to add effects on the way to CD. Do you know if your mixer has any channel inserts or effects sends? That's what I would use- like this:
Mic->Preamp->(maybe a compressor OR limiter if you're worried about clipping->)8 track recorder.
8 track recorder hopefully has 8 outputs- 1 for each channel. So:
8 outs from recorder->8 inputs on mixer.
Reverb machine is set up on an effects bus so I can add a little reverb to the drums, a little more to the guitar solo, a little to the lead vocals, and a little more to the backing vocals. The vocal effects processor goes into the channel insert of the vocal track so you can adjust the affect until its perfect- if you use it all.
Tweak and fiddle with the knobs, buttons, and faders until its sounds right, then:
Mixer stereo output-> Cd burner.
If you have the hardware to do it that way you'll
a) have better sounding dry tracks
b) have more control with how much and what kind of effects you use, and
c) way more control over the overall sound of your song.
That's why its called a mixer.
Take care,
