Is there anyone here who remembers how to do the mod to the 400 series that involves something really simple like cutting a resistor leg and then running a wire from one spot to another?  If sort of took the in-line switching capabilities away, but it was supposed to improve the sound.

The thread is obviously gone now, but it is something I'm still interested in trying.

any help with this? I too am very interested!

I acquired a console with that mod already in place. Initially, I was so confused by the console's routing when I first acquired it due to the in-line features basically missing.  Huh
That was a big reason as to why I became interested in the console in the first place...

I eventually decided to completely retrace all of the mods that were performed to the desk in order to really understand where the issue/non-issue was.

I since reverted a bucket of 8 chan's back by undoing some of the mods in the desk. I might have a schematic I can scan that details the mods

Hello Martin.

I would be interested to see any diagram you have.  I remember reading the description of this mod, but couldn't really get my head round it.
