Hello everybody. As usual I apologize for my bad English.
 
I recorded about two days a vocalist in a band and I do not like the result of the mix of his voice.
 
Have I hit a few details such as pitch and also some lapses of time, however, he has a very high, sharp and clean for the style that recorded music gets weird voice.
 
I would like to give an effect of drive in his voice and I've tried to let some half-saturated vocal strip and put a modulator, but honestly did not like the result.
 
Was wondering what plugin you show me so I can put a drive in the vocal effect without spoiling or dull the original voice.
 
Since now, thank you all.

I haven't done this in your specific situation yet, but generally speaking you can achieve more transparent drive fx by using parallel processing, meaning you have a "clean" or unaffected version of the sound running alongside the version with drive. You could do this easily by cloning the track, taking both faders down by about 6dB as a starting point, and putting your plugin of choice on one of them. Run the combination through a bus if you need to further process the vocals as a single sound source.

Some plugins offer parallel processing right from the plugin. E.g. the affordable but excellent Klanghelm SDRR is very well suited for fx like these.

Try a final limiter on the track like an L2 if you want more push on the vox.

...parallel processing, meaning you have a "clean" or unaffected version of the sound running alongside the version with drive. You could do this easily by cloning the track...

The conventional way to do parallel processing is to put a post fader send on the track to a bus on which the plugin resides. Set the plugin 100% wet, and control the FX level with the send level.

I personally prefer the two track approach as I find it a little easier to balance the two, plus it leaves me a more logical overview of buses and tracks.
 
For drums I use your version, usually cloning the bus or setting up a separate bus with a different mix, but there it makes more sense because you get the two buses (regular and processed) next to each other.
 

I find adding a little overdrive/saturation to the high frequencies helps.
 
I either use the VX-64 EQ, adding saturation only to the high frequency band, or the Saturation Knob, with "Keep High" selected.
 
Plus, using the PC76 followed by the Ca2a always gets nice results.
