INTRODUCTION
Founded in 1984, SWR specializes in quality amplifiers and speakers addressing the needs of the pro-
fessional and semi-professional bassist. Widely known as the makers of the finest bass systems in the
world, SWR has recently gained popularity among instrumentalists of all types, stemming from the intro-
duction of a series of products intended for the acoustic musician. SWR and its advisory board, consist-
ing of some of the world's finest musicians, have constantly strived to identify the changing needs of
musicians everywhere, and to respond with new and useful designs, each one unique unto itself.
Numerous requests from our customers to produce a line of products that would incorporate accurate
sound, high reliability, quality components, hand-made craftsmanship, and an overall low price, resulted
in the development of the Workingman's Series of amplification from SWR.
The precision electronic section featured in the Workingman's Series of amplifiers is entirely hand-built,
employing a variety of technologies selected for their sound quality and practical usefulness in a road-
worthy and studio-ready amplifier, including an all-discrete initial gain stage in the preamplifier section
and discrete solid-state design in the power amplifier. Regardless of its lower price, the Workingman's
Series offers no compromises of the essential SWR design and construction philosophy. Corners are not
cut from a more elaborate model: rather, each product's design parameters are conceived from the
ground up and the best available components are selected for each application. Once again, with sound,
reliability and price consciousness in mind.
The tone-shaping section of all Workingman's Series amplifiers, including the Aural Enhancer (found in
all SWR Preamps and Integrated Amplifiers) and the Tone Controls, will not impose a character on your
sound. They will instead make the interface between your instrument and the speaker system (two of
the largest factors in your final tone) a simple matter requiring minimal effort. The center frequencies of
the Tone Controls were chosen for their musical effect on most basses.
Everyone at SWR sincerely hopes that you are satisfied with your recent purchase, as we are extremely
proud of the quality and attention that goes into each and every SWR product. We truly hope that your
purchase of an SWR helps bring out the best in your playing and adds to your enjoyment of music.
