For example, here's what I'm talking about:
So, as an example (not a Marshall, I know) this: http://www.c3amps.com/Photos/SLOBuildLo ... roPots.jpg" onclick="window.open(this.href);return false;Do not solder the ground buss to the back of the pots. Instead, lift the grounded legs of the Midrange pot, Presence pot and both Volume pots, then run the buss wire through those, ground all input jack and preamp grounds on the same solder joint on the ground buss (right at the grounded leg of one of the volume pots is most convenient for this), then run 1 wire from that solder joint to the (-) terminal of the preamp filter cap and ground the (-) of the preamp filter cap to a chassis ground lug fastened by one of its clamp mounting screws. Everything else can be grounded the way they show to in the instructions.
Or this: http://i255.photobucket.com/albums/hh15 ... C00469.jpg" onclick="window.open(this.href);return false;
Not this: http://www.cpamps.com/images/000_0618.JPG" onclick="window.open(this.href);return false;
My main question is what's the result of doing it either way? Less noise? Are there any potential issues if one doesn't solder the bus to the back of every pot?
