Mesa/Boogie, hiss versus tone?

Andy	Mesa/Boogie, hiss versus tone? Hi In one of my Formula preamp's Lead channels there's a .001 uF disc-cap which comes from the grid of one if the tubes and runs directly to ground (don't have a schematic of the Formula). I know this is done to reduce hiss somewhat, but what i'd like to hear opinions about is,what effect does this have for the tone of the amp (dynamics maybe?) Since the Formula is a recording amp they could have chosen to sacrifice some tone for lesser noise. Should i get rid of these caps,or would it be neccesary to keep one in there? There's also one placed in the lead channel of the DC-2 just before V2A (I do have a schematic of this one). As far as i know most amps don't have this or placed! Let me know what you guy's think.
