If you have the Voicelive already then you dont need another preamp: the VL mic Preamp is a burr-brown based affair which I understand is the same as the TC Gold channel: Top notch in other words. Hence the line outs. You could send to (for example) Midas FOH line ins from it if you wished and not lose anything in the translation. Been there.

At the end of the day, K.I.S.S really works best onstage. Imho a simple distortion pedal is best bang for buck, assuming you can trust your vocalist to remember to switch it on and off. Keep it simple and modest and feedback wont be an issue, but anything involving exaggerated EQs will get you into trouble down the road.

Hope it helps.
