George Dennis The Blue BASSIC TUBE 120 Reference And Owner's Manual

BASSIC TUBE™ 120 and BASSIC TUBE™ 200 bass amplifiers
Congratulations on your purchase of a George Dennis Blue Line Amplifier. All our amps have been subjected
to all necessary mandatory tests required by both American and European norms and have passed in all
areas.
George Dennis is proud to introduce on the world market two brand new models of all – tube bass
amplifiers, this time using the standard E 34 L (120 W RMS ) and a hand – made, high precision KT88
( 200 W RMS ) tubes.
Bassic Tube 120 – 120 W and Bassic Tube 200.
Both models feature identical control configuration. Extra emphasis is being placed on offering the player a
full range of tonal choices, consequently resulting in accommodation of all playing styles while in the same
time highlighting the outstanding attributes of each individual instrument used. To meet the highest
standards in terms of both the best quality of a bass amp and highest expectations of accomplished
players, our amps are being made of the very best components available. There is no signal distortion even if
you turn both the Gain and Master Juice controls all the way to maximum. Alternately, when you play the
amp quietly you can still feel its hidden potential while retaining unaltered tonal properties. The footswitch
FSB 2 switches both the entire MIDDLE section and WARM function ON or OFF. At the peak the Bassic
Tube 120 will deliver as much as 230 W and the Bassic Tube 200 as much as 300 W. Tube amps are
generally much more dynamic than the transistor ones, hence the impression of more power. Both of these
amps boast beautifully warm and clear sound and differ only by incorporation of different power units, power
tubes and transformers. However, the preamps in both models are tuned in identical way.
Our philosophy as a prime source of guidance during development and construction of this bass
amp, broken down to four main objectives.
1. Obtain the desired sound when using any type or make of an electric bass guitar.
2. Attain high sound level without jeopardizing dynamic properties.
3. Create sufficient power, dynamics and sound color in reserve, especially in the bass and sub bass
frequencies.
4. Enable the player to use the control configuration creatively, maximizing his/her chance of arriving at
that personal sound.
Bassic Tube™ 120 – 3x12AX7 a 4x E 34 L, 120 W RMS, parallel stereo FX Loop, direct out, output for
tuner and pre amp out.
Bassic Tube™ 200 – 3x 12AX7 a 4x KT-88 (hand made), 200 W RMS, parallel stereo FX loop, direct out,
output for tuner and pre amp out.

Operating your amp.

Operating the Bassic Tube is very simple. You have one channel. Gain – signal intensity in the preamp and
Master Juice ( slang for Master Volume ) – power gain in the power end. Furthermore, you have the pot
HEAT which is actually gain number two and enables you to emphasize the sound core as well as control
elements of tonal coloring, described in the layout of the front and back panel. Do not overlook the + 6 dB
switch, which enables you to boost the sound level at a flick of a finger.
