1
The Channels of the Edition Blue™ DFX
The Edition Blue™ DFX is equipped with two channels, Clean and
Lead. Its innovative circuit design, which simulates the important
sound-forming elements of tube amps using semiconductor technique,
gives both channels the dynamics needed by a discerning guitarist for
his/her musical expression. The sensitive preamp of the Edition Blue™
DFX not only produces harmonious overdrive but also a significant
dynamic response to the style of playing.
1.1 The Clean channel
Depending of the preamp control settings, the amp can produce a
variety of contemporary and „vintage“ Clean sounds.
1.2 Volume
Determines the Clean channel‘s Volume. Depending on the type of
pick-ups, the amp will begin to clip somewhere around the 12 o‘clock
setting. If desired, the Clean channel can produce a lot of crunch.
1.3 Channel Select
This Channel Selector switch activates either the Clean or Lead channel.
The Lead channel is active when the button is pressed.
1.4 The Lead channel
Classical, open rock sounds – direct and dynamic. In particular the
effective sound-shaping tool facilitates a large spectrum of Lead sounds.
1.5 Lead Gain
Controls the amount of distortion in the Lead channel.
1.6 Lead Master
Determines the Lead channel Volume Level in relation to the Clean
channel Volume Level.
1.7 Bass, Mid, Treble
The sound control works for both channels. Mid and Treble controls
influence each other (as is also standard and desired on tube amp
models): if you boost the treble, it causes a central lowering and vice
versa. This characteristic enables the greatest possible variety of sound
nuances.
1.8 Master
Controls the Master Volume of the Edition Blue™ DFX inclusive of the
effects. The Line Out signal remains unaffected by this control.

The Effects of the Edition Blue DFX
The Edition Blue DFX is equipped with two independent „signal
processors“. Signal processor 1: modulation effects and Delay, Signal
processor 2: digital spring reverb. Both signal processors can be used
at the same time and are independently adjustable. The settings work
for both the Clean and the Lead channel.
2.1 Preset Adjust
The first effect section of the Edition Blue™ DFX offers you the two
most important modulation effects, Chorus und Flanger, as well as
Delay. They are behind each other on the Preset Adjust control. In the
first section, the Chorus is active; in the second section, the Flanger
is active and in the third section, the Delay. Within a section, you
can change the character of the effects with this potentiometer. The
parameters are selected in such a way that it creates good quality
sounds which Lead quickly and simply to the desired effect. Through
clockwise rotation, the speed (rate) of the modulation effect changes.
Dependent on the rate, the modulations depth is automatically
regulated in such a way that in every control position the best possible
sound effects are always heard. With Delay, the Delay (time) and the
number of repetitions (Feedback) change at the same time. The mixing
ration between „dry“ signal and the effects can be infinitely variedly
regulated with FX Level.
2.2 Chorus
With slow adjustments, the Chorus sounds deep and rich, which
works best for floating ballads. Thanks to the automatic effect depth
adjustment, quicker Chorus adjustments don‘t „scream“.
2.3 Flanger
The slow Flanger settings give an intense sweeping effect, while with
rapid adjustments you can produce current rock and pop effects.
2.4 Delay
With the Delay control, the time to the next repetition can be varied
infinitively from 80 ms to 1400 ms. Feedback is automatically adjusted.
Short Delays with little feedback are best suited for „rockabilly“ sounds,
intermediary Delays are perfect for typical „U2“ sounds, while long
times are good for playing the canon-like „Queen“ licks.
2.5 FX Level
This control determines „how many“ Chorus/Flanger/Delays should
be mixed with the sound. At the left control the signal is „dry“, effect
section one more or less switched off. At the right control, a mixing
ratio of 1:1 exists. The FX Level control works independently of the
Reverb control.
Only for Edition 30 and 60 DFX: the FX section can be switched on and
off with the Footswitch. As with the FX Level control, Reverb works
independently. See also 3.3 Footswitch.
