Bass: Bottom end voicing control for both channels.
Middle: Mid-range voicing control for both channels.
Treble: Upper range voicing control for both channels.
Leaddrive: Gain for the Lead channel, controls the amount of preamp overdrive
in the Lead mode.
CAUTION: Extremely high gain and volume levels in the Lead mode can produce
strong feedback. Avoid feedback squeals, they lead to hearing loss and
damaged speakers!
Reverb: Reverb control, adjusts the portion of the reverb signal and increases
reverb intensity when you rotate it clockwise.
Preamp sound switches:
Gain Boost: Bass and Gain boost of the input stage.
Mid Boost: Boosts the mid frequencies at 500 Hz.
Bright: Alters the EQ by boosting the upper treble range.
Bypass: Defeats the EQ (Bass, Middle, Treble).
Clean/Lead: Channel selector switch for Clean and Lead; This feature can also be
switched via the footswitch jack "Clean/Lead" located at the rear panel: the
channel selector switch is deactivated once a footswitch is connected to the
footswitch jack.
The red LED beside this switch indicates Lead channel activ.
Poweramp controls:
Clean Volume: Master volume control for the Clean channel (located post FX loop). Use
this control to adjust the ratio between the Clean and the Lead Volume.
Lead Volume: Master volume control for the Lead channel (located post FX loop). Use this
control to adjust the ratio between the Lead and the Clean Volume.

Fuse: External mains fuse. For values refer to "technical data".
NOTE: The value must correspond to the available current.
CAUTION: Ensure replacement fuses bear identical ratings!
Voltage selector: This selector must be set to the correct value that corresponds to
the available current, e.g. 120 Volts in the U.S., 220 Volts in
Germany, etc.
CAUTION: Before you power the amp up, ensure the voltage value set at the
voltage selector corresponds to the available current.
Footswitch: 1/4" jack for connecting a footswitch; it executes
channel selection between Clean and Lead.
Send: Signal output for the FX Loop. Connect this output to a signal
processor’s input/return jack via a shielded cable with 1/4" plugs.
Return: Signal input for the FX Loop. Connect this input to a signal
processor’s output/send jack via a shielded cable with 1/4" plugs.
8 Ohms: 8 ohms speaker output jack, the internal 8 ohms speaker
is connected to this jack. You can connect an external 8 ohms
speaker cabinet instead of the internal speaker.
NOTE: Never operate the amplifier without a sufficient load, otherwise
you may damage or destroy the power amp! Ensure your
cabinet’s specifications match the respective output’s specs.
Technical Data:
rated power: approx. 30 Watts at 8 ohms.
Tubes: V1 (Input tube): ECC 83 / 12AX7, FQ selected;
V2, V3: ECC 83 / 12AX7, selected;
V4: ECC 83 / 12AX7, standard;
V5, V6: EL34 matched set.
fused external: at 230 Volts: 1,25 A
at 100 and 120 Volt: 2,5 A
fused internal: 2 x 1,6 A;
plate fuse: 0,5 A;
CAUTION: Replace fuses only against same type and rating!

Protect the amp from mechanical knocks (tubes!).
Let the amp cool down before you transport it (approx. 10 minutes).
Tubes need about 20 seconds to warm up after you switch the power on,
and furtheron a few minutes before they reach their full power capability.
Avoid storing the amp in damp or dusty rooms, they are hard on jacks,
switches and potentiometers.
Make sure air can circulate at the rear side and the top of the amp
to allow for adequate cooling (increases component life).
Never operate the amp without an adequate load.
Replace tubes with select replacement tubes (special selection criteria)
to avoid microfonic properties, undesireable noise and unbalanced performance.
