This 1980 advert for the Lab Series amplifier range was published in Guitar Player in 1980, and is made up of quotes by Gary Cooper (who proffered the title), Alan Holdsworth, and Whitesnake's Bernie Marsden.
Alan Holdsworth: My curiosity about amplifiers is unlimited. Having tried Lab Series, I now use a pair of L5 combos as part of my stage set up; they're DEMONS!
They deliver a really good clean sound and the tone controls are very flexible. They can also handle a very strong single notes sound, which in the past I found to be very elusive.
Bernie Marsden: I've had transistor amps before, but I've never thought of using one on stage until the Lab Series came along. I must admit I was really surprised; they changed my preconceived idea of a transistor amp. What is different about them is that all those controls - every one of them actually does something. Most amps you see have got seven or eight knobs, but the only ones that actually work are volume and treble. But with these, the frequency, mid range, multi filter – they're a piece of work really!
