can you hear me now...
another idea, it seems your actually in the Tracking phase...overdubbing, you mentioned.
if this is the case why not just record a few takes of the Feedback Distortion guitarist and then unplug it,
then sit back and listen thru the monitors & see if the take was good.
at a normal level.
if no good re-Track.
a really nice lesson that BMWerks gave me was not to
confuse Mixing stage with Tracking.
Instead of what i was doing panning and Eqing while tracking,
i now concentrate to get the best performance and sound going in.
It really helped me & prevented alot of song burn out.
Its like you get it on tape/hd... fresh... if you get a decent Mono, your setting yourself up in a good way.
then later i ruin it with poor mixing skills!!
