At the end of the day, we all need to know that our cables are going to last a while and won’t die on us mid-gig. You just know it’s going to be good when PRS have put their name on it. Conversely you will rightly feel like a complete space cadet if you put "foreign intelligence services" on the threat model for a curtain retailer, and that keeps things a bit more rooted in the plausible (as opposed to the technically possible). I plugged in my daughters charger to my old sweeper by accident and fried the circuits in my old sweeper, so I bought one from Ebay, only to find the stupid woman had put in a charger that doesn’t belong to the carpet sweeper. Electric guitar cables contain smaller amounts of capacitance, which are measured in picofarads (pf); each one million-millionth of a farad. UF, or underground feeder cables, are common for running power to a shed or garage, and metal sheathed cables such as BX are common for outdoor use.4.
We’ve had good experiences gigging with these great value patch cables, and Ernie Ball even makes the Flat Patch Cable in white as well as the ubiquitous black. This is where ‘capacitance’ comes into play - capacitance is a buzzword you'll often hear around guitar cables, and for good reason. And this means it is more adversely affected by capacitance from a cable to create a filter on your sound - as capacitance and impedance increase, this filter comes into effect more. Active pickups contain a preamp that offsets any issues with impedance by converting it to low impedance, and it can drive a cable without any loss of high frequency. The output from most electronic audio devices is usually low impedance (around 150 ohms), but it can be much higher for passive guitar pickups. Despite a balanced cable being objectively better, unfortunately, as guitarists, we cannot use them with our setups due to the way our pickups work. Journeyperson electricians can work unsupervised provided that they work according to a master's direction. The work will be inspected by a designated authority at several stages before permission is obtained to energize the wiring from the local electric utility; the inspector may be an employee of the state or city, or an employee of an electrical supply utility.
When I was working on an (otherwise well run) government system it took ages to get permission to see the threat model. Of course, this isn’t a solution for every potential problem, but if you fear your cable is faulty, try it on a different amplifier or guitar and see if you can recreate the issue. Though black is available, funkier choices of Neon Pink and Orange will ensure you can see your guitar cable on low-lit stages, though we’re rather partial to the red, blue, and white design ourselves. The quality of your guitar or patch cable will definitely influence your tone. A decent quality audio cable should offer 40pf per foot with the highest quality offering around half that. They can also present issues when plugging into our amplifiers, as some amps won’t be compatible with the TRS-style connector on a balanced cable. They’re handily available everywhere too, so you won’t have to look too far if you decide you want one as a backup.
If you need custom lengths for your pedalboard, a solderless kit is an easy, accessible option that won’t require an electrician’s skills. What Level of Security Do You Need? Coming in a variety of size options, they’re perfect if you need to wire your pedalboard or expand your reach onstage. Guitar cables are unbalanced, which means they’re prone to interference. Numerous newspapers and news outlets in various countries, such as The Daily Telegraph in Britain, The Telegraph in India, De Telegraaf in the Netherlands, and the Jewish Telegraphic Agency in the US, were given names which include the word "telegraph" due to their having received news by means of electric telegraphy. This means that PRS instrument cables have low capacitance and fantastic noise rejection, so there’s no compromise in strength and tonal fidelity for the studio or the stage. A current as low as 30mA can cause ventricular fibrillation, so RCDs (residual current devices) that detect earth leakage faults are designed to trip and shut off power when a current of 30 mA flows (e.g. if you touch a power cable). Can guitar cables cause buzz? Whilst a bad cable certainly can cause a buzz, it wouldn’t necessarily be our first port of call when looking to get rid of a noise issue.
