I've been searching for cable with 4 or 6, tip sleeve 1/4" conductors.... ( shielded )  maybe 12' to 18' in length. This is for a pedal board to amp run. I did a few searches and didn't find anything useful. Seems there's got to be clean way to run cabling to an amp stack besides separate cables and tie wraps. You know space age technology - turn of century etc.

Have you tried the Sweetwater cable finder:

Try searching for 4, 6 and 8 core multicore snake cable. I can certainly find 4 and 8 way easily in the UK/Europe so it probably can be obtained anywhere. 6 way is harder to find because it's not a "standard" configuration. You may need to solder on your own jack plugs though, multicore is generally intended for balanced use with XLR or TRS plugs. To use it as a basic core and braid cable just connect the braid to the plug sleeve as usual and both cores to the tip.

Thanks for the info. 
I did finally find a few options designed just for this purpose . In case anyone else is looking for something similar.
