Ok, I have a small mixer with a mic preamp. It only has one send and one return. I have a nanoCompressor and a nanoVerb. What path should the audio signal follow for the Mic? I have a synth going through the mixer also and I don't want any effects on it or on the mixers's main outs, just the vocals. So, can I chain the compressor and reverb using the mixers send and pump it back through the return? Is that a big no no? If I can, should it be compressor then reverb or the other way around? Of course I can just try it all out, but befeore I do I thought I'd ask 
Thanks in advance!
