I bought my only wireless unit in 1989. It was analog. You could turn it up and it could boost an amp, which was kind of cool. It actually had a sound of its own, which, depending on the guitar and amp, could be a good thing or a bad thing.
About a decade later I graduated from sniffing bicycle seats to corks, so I became a purist and went back to using a cable.
True story: Two-Rock sent me a solid-core cable to try out, and it was so stiff that it couldn't actually be uncoiled. It was more like a giant Slinky than a guitar cable.
They didn't offer it for very long. It was great sounding - like, no high frequency signal loss - but it was impossible to use in the studio or live.
Of course, for a cork sniffer such as myself, it was perfect for that very reason.
And no one wanted to steal it. It would have been hard to steal something that only coiled up as small as a bicycle wheel.
One of my session guys liked it, so I gave it to him.
"I'll bet you never went back to using a wireless again because of your affinity for sniffing corks, right?"
"I never went back to using a wireless again because I couldn't find my wireless unit when I realized this business of having a cable to trip over was pretty stupid. But I kept forgetting to replace it for the past 25 years. Now that I look at the price of the top units - which of course I must have because corks must be sniffed - I just keep using cables in the studio because I'd rather buy dumb stuff like microphones and instruments."
"You realize you're out of your mind."
"So what. I have dementia as an excuse."
