SWR WORKINGMAN’S 4004 Owner's Manual page 2

INTRODUCTION INTRODUCTION
Founded in 1984, SWR specializes in quality amplifers and speakers addressing the needs of the
professional 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
introduction of a series of products intended for the acoustic musician. SWR and its advisory board,
consisting 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
roadworthy 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.
SWR amplification is handmade and individually tested in the United States. 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.

The Workingman's 4004 comes enclosed in a sturdy, custom fitted rack, covered in midnight blue carpet
with stack lock corners. The rack case was designed specifically to house the Workingman's 4004
chassis and features a single open rack space (directly below the amplifier) for mounting the effect unit of
your choice. Most single rack space effect units or digital tuners on the market today will mount perfectly
into this space.
