Compressor Bypass – Turning the Compressor control OFF will disengage
the compressor.
Enhance Control – Called the “Magic Knob” by some, this complex
control simultaneously boosts the very low bass, upper middle, and high
frequencies while putting a dip in the lower middle frequencies.
It is flat when set to its minimum level (fully counterclockwise).
Tone Control Section
These three controls and two switches allow you to boost or cut the tone at
the desired frequency. The spacing allows the controls to interact smoothly
and musically. From left to right, the controls and switches are:
Bass – This traditional shelving tone control provides 15 dB of boost or cut
at approx. 30Hz. The control is flat in the 12:00 position.
Tone Bypass Control – Located between the Bass and Mid tone controls. A
great tool for recording, this bypasses the tone section only and does not
effect the Dynamic Boost or the compressor.
Midrange Control – This covers the center portion of the sound envelope
and can be critical to getting your sound right. The body of the Bass Guitar
sound is in the Midrange.
Mid Shift Control – Located between the Midrange and Treble tone
controls. This switch shifts the Midrange control from low mid (550Hz),
which is good for general playing and recording, to the high mid position
(2.2KHz) for Rock and more aggressive tones.
Treble – This traditional shelving-type tone control provides 15 db of boost
or cut at approximately 11KHz. The control is flat at the 12: 00 position.
Dynamic Boost – Immediately to the right of the Treble control you will
find two switches labeled Bass and Treble. These engage the Dynamic
Boost. This feature allows the extreme lows and highs to be adjusted to the
ear’s relative loudness curve (Fletcher-Munson curve). This ensures the bass
will sound full and solid, even at very low playing levels.

Using the WT405 Without Speakers -This amplifier is designed to be used
safely with headphones only, without the loud speaker plugged in. No harm
will result from using the amplifier in this fashion. This allows the use of the
unit for practice with headphones and as a preamplifier with other
amplifiers. Like we said earlier, neighbors and room mates really love this,
which qualifies it as another Really Neat Thing.
MAINTENANCE
Your Eden amplifier has been designed to require minimal routine
maintenance. Attention to the following areas will ensure optimum
performance of your amplifier. We’re serious. Don’t blow this off, OK?
Contact Point Cleaning – One of the weakest links in most bass
amplification systems are the solderless connection points where
instruments, speaker cabinets, effects, and other devices are connected to the
amplifier. (The most vulnerable of these types of connection is the jack on
your instrument). In addition to contamination from airborne pollutants,
these points are frequently assaulted by connectors that have picked up
debris from dirty stages, cases, etc.
This contamination can result in poor contact as well as poor tone, and we
all know that bad tone is a Very Bad Thing. These points should be cleaned
regularly with a cotton swab soaked in denatured alcohol or a commercially
available de-oxidant. Frequent cleaning of the plugs on your cords is also
recommended.
Dust Removal – You should periodically inspect the ventilation openings
on the top and sides of the unit to ensure that they have not become blocked
by accumulated dust. Vacuum the openings to remove any dust buildup.
Dust bunnies are definitely not cool.
CLIMATE AND TRANSPORTATION
Routine temperature extremes (such as cold garages) will not harm your
WT405. You should, however, allow the system to adjust to room
temperature before playing it at loud volumes. If your cabinet is going to be
bounced around severely during transportation, it is best to avoid loading it
with the speaker cones facing down, as this puts added stress on the screws
that secure the speakers in the cabinet.
