Second Supplemental Report
Working with a vendor, I ordered some cables made by the Dutch company, Grimm, their TPR model. These are actually balanced, stranded cables that can be wired unbalanced for guitar use, like the Van den Hul I used on much of the board. They're shielded quite well, though I'm not certain of their capacitance.
They're supposed to sound similar to the Van den Hul, which I've been happy with for years, so all should be well.
Poking around the internet, it seems that this Grimm cable was developed for Wisseloord Studio in Hilversum, The Netherlands (near Amsterdam).
I've worked at Wisseloord. It's one of the finest studios in the world, with the best, no-holds-barred equipment and rooms. At the time it was owned by Polygram.
So I went with the Grimm cables just because I had such a great time when I booked Wisseloord for sessions!
Turns out also that G&H is making some plugs with a thinner profile for pedalboards. I decided to go with those, even though they don't exactly match the larger plugs I'm using.
I'll switch the whole board over to these plugs as time goes on in the interest of saving a little space. For now, however, I want to see how well the cable works.
I'm replacing all of the Evidence Monorail cables that have to flex as the board's upper shelf is opened and closed. I figure that solid core cables aren't really optimal for repeated flexing. I'll keep a few that interconnect to gear on the lower shelf, since nothing has to flex there.
As stated, while I'm not going Full Simon on this board, it'll get tidied up even more when the new cables are installed.
