Have you tried a new battery? A Rat with a weak battery tends to compress the initial attack down to almost nothing at high gain settings.  
Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.

New batt, same problem.  
Light pick attack is ok but med to  
heavy attack causes cutting out especially  
on the low strings.  
Backing guitar vol to 7-8 makes the  
problem disappear.

Sounds like you're overloading the input of your rat. Do you have any pedals in front of it? or do you have a built in preamp in your guitar? Real hot or active pickups? A booster or anything?

If all else fails, it could be the op-amp. I've never seen this problem with a RAT before, but I've had an MXR pedals do the same thing. It's a long shot though!

I use guitar-rat-hiwatt100.  
Dimarzio super-distortion is in one  
guitar which probably pushes the rat,  
but my other guitar is an old gibson with  
soapbars. Same results.  
I'll try to track down another op-amp.  
Can i try a different type?  
Where's a schematic?  
Thanks all.

There's two different revisions; pcrat.gif and pcratb.gif  
Hope this helps.
