Sorry chaps!
I did not mean to imply that I have found the answer to the meaning of life WRT cables!
No, the capacitance of the hot core to screen is decided by the cable type and construction as always but I meant to make it clear that the LOWEST capacitance is given by using just one core.
I have a 100mtr drum of (very poor quality) mic cable handy and the capacitances come out thus..
Core to core 160 puff per mtr
Red core to screen 260ppmtr
white core to screen 321ppmtr
red with Wt to scrn 263ppmtr
r+w to screen 527ppmtr
This is very small diameter cable and bigger, ~6mm mic cable would have lower capacitances. The cheap stuff is however quite good enough for semi-static patch leads in a home studio!
BTW I measured the capacitances of the whole drum with a Fluke 83 DMM and divided by 100!

Like to say to Mr Dammned!
If you have a lot of plugs to fit buy a tube of silicone grease. Makes the screwing a lot easier (shut up at the back there!!)
I "acquired" a tube some 5 years ago and have made up 100s of cables since and I still have some left!

Smart! That's an excellent plan. Cheers
LOL
Theres not getting away from the fact that Neutrik demand a huge amount of pedal board real estate. For every 6 pedals they will take up about a pedals worth of space. Switchcraft pancake jacks take up far less room, but for maximum space Lava cable jacks and cable cant be bettered IMO.
Do you have a link to the lava stuff? I suspect it'd be more than I want to pay, but I might as well take a look anyway to see what the options are. Currently I'm considering the hicon ones, since kabl and thomann offer them (as ready-made cables) at a reasonable price.

TBH I dont understand why anyone would use soldered cables for a pedal board, the convenience, space saving and reliability of the Lava cables is a no brainer to me. I had terrible trouble with George L cables but the Lava stuff has been ultra reliable.

Both were... Er... Greasy. Worked a treat Thanks for the tip!
Thanks
"Pete Cornish uses Belkin 8412 for all his interconnects. It's relatively cheap but outstanding cable "
I can find little hard data on 8412 except that its capacitance is given as 33puff per FOOT* which is of course some 99pp mtr and a tad over the suggested limit for low "suck"!
However, that capacitance figure is not qualified as to core (which?) to screen or core to core and as we have seen, that matters a lot.
Personally I would not sweat the cap' value. I would think most amps could make up the loss with tone pots? OR! Buy or make a buffer!
I know there are purists out there that get twitchy with the very thought of "silicon" but a well designed op-amp buffer really is transparent. There are now better FET chips than the venerable TL07X series, ones that will swing closer to the supply rail if you insist on only 9volts. I would personally go for 12.
*Beware if checking cable capacitances. In addition to knowing what the measurement applies to the figures can look good until you realize it is Yanky specc' and puffs per foot. Here capacitances are usually given in pp mtr.
Same goes for resistance. X Ohms per 100ft is NOT the same as 100mtrs! (or indeed 100 yards)
Not that cable resistance really ever bothers us. (Oh! And be careful who sees Vaseline in you workshop/gig bag!)
