My buddy is always buying big spools of this low capacitance, shielded 2 conductor cable and I trade him pickups and stuff for smaller spools. Its meant for Pro Video purposes, but has great audio specs for transmitting high impedance, low voltage signals like, say, a guitar signal. Its very light cable and has a tendency to tangle and is easy to break. I typically do not use one of these coming out of my guitar for that reason, but all my patches from tuner-out to amplifier input are this stuff with whatever jacks I have laying around. I usually do L ends. I like them for amp ins.
Apart from the awesome treble response, dynamics and signal-to-noise I make these cables myself because I can cut each one to be precisely the length I need. The cable pictured is meant to daisy chain 2 ac30s together (for when I want to get an old school 2 amp sound bridging 2 different pres). Plus its cheaper than purchasing cables. They're free really. I get the wire in exchange for stuff I'm not using anyway and I tend to use jacks I have laying around from cheap broken cables I am always scooping up when guys discard them. "You're just throwing that cable away? I'll take it!"
I have made so many custom cables over the past 30 years, I don't how many I have made. This includes 1/4" TS patch cables, guitar cables, pin-tip modular cables, 10 foot and longer twin RCA cables using high grade mic cable, speaker cables from two foot to fifty foot long, video cables, a custom 4-pin to pin-tip keyboard interface cable for my modular system, 4-outlet power cables, DC power cables for multiple modular cabinets, not to mention custom cabling for clients.
