Thx that would be great Dave.
btw I went upstairs and checked the DFP Box

Gavin was right the connectors are incompatible (I thought they are).
DFP = D-Sub Connector
MS = RJ-xx Connector
Then I had an idea (oh no)
I compared the potentiometers and they are identical in size etc.
MS FF poties made half of plastic but they are in a really good condition
DFP's are made of steel
Now I swapped both DFP poties with the MS FF and it worked,
but because of the size of the male and female RJ-xx Connectors the backside of the DFP pedal-box can't be closed anymore.
I tried many diff. positions and in the end I accidently ripped off a few of the little cables while closing the cover. Damn.
And no electric soldering iron in the house because the last time I performed handicraft work was when I created a read/write protect switch with red and green light-emitting diodes on my Amiga 500+ iirc
Oh well me and my late night ideas
