Effect sends and return in VST32!?

[Sen]

Hi guys,
I'm using VST 32 5.1. I use the fx sends as the inserting effects into the separate channels eats up a lot of cpu power. I send the channels to the effects, but have problem with the effected signal that's returning.
Ok, let me explain:
Let's say I send a rhythm guitar and a lead guitar to the same reverb. Lead guitar is panned to one side let's say, and rhythm to the other.
When I solo the lead guitar I can hear the 100% wet rhythm guitar sound coming into the lead guitar channel. Can these be separated and how??
thanks for all the help ...

cheers

Sounds to me like it's a mono reverb. You can send all the stereo signals in the world to it and you'll always get a mono return. Is this a plugin effect or an outboard FX unit? If it's am outboard unit, see if it has a mono/stereo switch. If it's a plugin, find another one like freeverb.
