Hi all,
I have pretty much completed tweaking the ruby tuby. The latest schematic is here:

Listen to the dirty clip 2. This was recorded from the amp straight into a PS04 from ZOOM (direct in, no mic). The sound is much bigger when coming from a speaker!
For anybody interested, one could simply take the opamp and tube portion of the ruby tuby and make a distortion pedal out of it.
All comments and suggestions are greatly appreciated!
Cheers,
Stephane.
