So let's be clear.
1) If you simply play back your dry track thru the Reamp patch... your signal chain sounds clean? Yes? No?
2) If you engage record ready, the playback thru the Reamp patch gets fizzy? Is input echo engaged?
That doesn't seem like a gain stage problem... but it can be.
It seems like the issue is specific to your setup and the Lamba. Does it have any sort monitor capabilities?
The easiest thing to suspect is that your monitor routing is sending something extra down the line and blowing out the gain.
It's also possible that fizzy sound is simply digital coughing from the system because you are somehow hitting a performance threshold.
The first thing I learned while Reamping is that the line level gain coming out of my I/O hardware is smoking hot compared to a guitar pickups signal. That is of course to be expected... and that is exactly what the Reamp device is for.. but in any event, I find I have to back off the levels at both the I/O (I just turn down the track in SONAR) and on the actual Reamp device.
I don't think that anecdote helps... but it may keep you comfortable while you sort this out.
best regards,
