WR Goliath Tube Bass Emphasizer “DI”

The WR Goliath Tube Bass Emphasizer “DI” is an exciting new development for bass players wanting
the richer, enhanced tonality associated with tubes.

This unique and innovative design is based on a specialised and limited availability ECC86 NOS tube,
optimized to operate on 24 Volt DC, to create wonderful tone in a limited-edition, hand-built unit.

No bass pedal board should be without one!

Equally effective across the frequency range (20 Hz – 18 KHz), from low-level to LOUD, the quality of the
sound is consistently high, allowing the same amazing sound on stage as achieved in the studio.
Tone controls and switches allow creating unique sounds, thanks to the way they interact together.
The Goliath will not change the basic sound of your Bass Guitar(s) as other preamps often do.
The Goliath is equipped with a “DI-XLR” Output for galvanic isolation with a “Lehle LTDI-L transformer”.
The “DI” Output also works in "bypass mode" and even without connecting the power supply.
This unit is also wired for “true bypass” operation.

Description

• The WR Goliath Tube Emphasizer “DI” was created as a way of adding the warm harmonic

sounds associated with the use of tubes to set-ups using solid-state amplifiers: to ‘push-up’ the
sound.

• This unit is powered by a 12 Volt DC power supply and operate internally with 24 Volt – as

required by the tube. This special feature of this pre-amp ensures user safety because there is no
high voltage on interior or exterior components.

• The Goliath has been designed to give the best results: a great sound from a robust and easy to

use product. The construction methods and components used are selected only for their high
quality and the positive effects they contribute (paper in oil capacitors).

• The Goliath is not a mass-produced product. The components are carefully checked, and then

each unit is assembled individually, using point-to-point (hand soldered) connections.

• All these steps combine to create a limited edition, hand-built pre-amp of the highest quality

that will enhance the sound of any bass guitar setup.

Features

• The WR Goliath Tube Emphasizer “DI” allows you to get the warm harmonic sound of an

electron tube, combined with a little more compression and, if necessary, a higher output volume.

• The Goliath can also be used as standalone unit, for example as a direct plugin to a mixing table

or a recording unit etc. in this case be sure to use the symmetric “DI-XLR Output”

• The "GND/LIFT switch": move the ground button on "Lift" position to eliminate hum. If the

ground switch is on "Lift" position the built-in “Lehle” transformer ensures galvanic isolation
between the shielding of the Goliath and the earth conductor of the XLR cable attached. If this
setting generates hum, activating the ground switch may solve this. When the ground button is on
position "GND", the shielding of the DI and the earth conductor of the XLR cable are connected.

• The “Tone controls” Treble, Middle and Bass allow you to have a good overall sound control,

with a good basic Bass sound. The output sound is created by the combination of the settings of all
three controls: the frequencies affected by each control are changed somewhat by the settings of
the other controls. This allows more frequencies possibilities.
