March 1979 advert for a new amp in the Lab Series line up. The L3 was the smallest amp in the Lab Series range: a 60w combo with a single 12" speaker. It was also slimmed down in terms of controls. Whilst it had the basic volume, treble, bass, midrange and reverb of the other amps in the series, it lacked the midrange frequency and multifilter: arguably the most exciting features of the Lab Series amps.
There's nothing fancy about the new Lab Series L-3 amplifier. But the moment you flip the on-off switch, it delivers what you want from any amp – outstanding sound.
The L-3 puts out musical, high energy sound and keeps a cool, quiet head hour after hour. It's also loud. Loud enough to quiet any other amp its size – 60 watts of continuous average power. And if you say tubes sound better, you'd better hear the L-3.
Of course, an amp isn't good if it can't deliver where it counts – from one job to the next. The L-3 is ready to roll with solid wood sides that are finger-locked at the corners and twice as much speaker support than found in most amps. And its weight is surprisingly light for such sturdy construction. There's a lot more to the L-3 than meets the eye. Because this new Lab Series amp is a lot of sound for its size. And that's what you and your audience really want to hear. Try one at your nearest Lab Series dealer. The L-3. A little amp. A lot of Lab.
