The channels
The amplifier has 2 separate channels, each with its own "GAIN" and "VOLUME" controls.
Furthermore, each channel has its own tone control and additional settings for the sound.
The channels can either be switched on the unit using the "CHANNEL" switch or with a
footswitch ("FOOTSWITCH" socket on the back).
Note:
The channels are switched via high-quality relays. A sophisticated, digitally controlled muting circuit with field effect
transistors prevents cracking when switching. The field effect transistors used here are used for only a fraction of a
second of the torque and have absolutely no influence on the signal processing and thus on the sound of the
amplifier.
“GAIN” + “VOLUME channel controls 1
Channel 1 has its own "GAIN" control and is thus able to produce clean and crunchy to relatively
strongly distorted sounds. For a clean sound, the "VOLUME" control should be set between "5-
6" and the "GAIN" control should be used as volume control. With this channel, sounds with
crystal clear trebles can be produced. The further the GAIN control is turned down and the
VOLUME control up, the cleaner the sound.
For distorted to heavily distorted sounds, the GAIN control is used for the distortion level and the
VOLUME control for the volume.
Note for the "blue note" with built-in tweeter:
For channel 1, the tweeter (using the "TWEETER" switch on the rear of the amplifier) can be switched on or off.
When operating channel 2, the tweeter is automatically switched off. By removing a solder bridge on the main
board (only to be carried out by qualified personnel), the tweeter also remains on in channel 2 and can then be
switched on or off in both channels via the rear switch.
“GAIN”, “TONE/DRIVE” + “VOLUME” channel 2
Channel 2 is intended for slightly distorted, crunchy to heavily distorted and sustain-rich sounds.
It has a "TONE / DRIVE" control, with which it is possible to massively influence the type of
distortion. The more it is turned up, the softer and warmer the distortion. At the same time the
gain increases and thus the sustain. Thus it is possible to produce sustain-rich, fat lead sounds
with the "TONE / DRIVE" control turned up. With a correspondingly low GAIN control, however,
slightly distorted, bluesy sounds can also be achieved. The reverse setting ("TONE/DRIVE") in the
"0" direction produces crunchy to hard but still harmonic distortions.
Both "GAIN" + "TONE/DRIVE" controls control the amount and sustain of the distortion, with
"TONE/DRIVE" affecting the sound character.
The "VOLUME" control adjusts the volume for this channel.
Note:
When the controls are turned up very high ("GAIN", "TONE/DRIVE", "BASS", "MID", "TREBLE" + "VOLUME"), it can
cause strong noise.
However, these settings do not correspond to a sensible operating state and do not indicate a defect. Please note:
In the development of this amplifier, great importance was attached to versatility in addition to good sound. Among
other things, this includes the fact that the power amp can be overdriven with undistorted, or slightly distorted
preamp ("GAIN" control low, "VOLUME" control high), or a very high-grade clean sound ("TONE" -switch up, "DEEP"
switch up "TREBLE" control up, "GAIN" control low, "VOLUME" control up).
With such practical settings, the noise described above will not occur.
