FREQUENCY COMPENSATED LINE
OUTPUT: LEFT
Line Out for the preamp's left frequency
compensated signal (1/4" unbalanced jack;
related to ground).
This signal can be patched directly to a mixing
console or a recording device. Ensure you use a
shielded cable for this signal circuit.
INSTRUMENT OUTPUT; TO GUITAR AMP
This is a frequency-compensated preamp signal
output. You can patch a cable directly from this
output to the input of a combo or head. Ensure
you use a shielded cable equipped with 1/4"
plugs.
The difference between the two MONO
outputs (29) and the INSTRUMENT out (30) is
that the Instrument output signal is filtered
when the preamp is active. A common problem
when you are routing a preamped signal to a
combo connected in series is that the combo´s
voicing section causes high-end distortion. This
filtered circuit is designed to prevent this
nuisance from rearing its ugly head, which is
why the INSTRUMENT output is the one you
want to use when you are routing the signal to
the instrument input of a combo or head. The
MONO output (29) can be used to patch the
signal directly to a mono poweramp (for
instance to the effects return of a combo or
head).
30
24
LINE OUTPUT: RIGHT
Line Out for the preamp's right channel (1/4"
unbalanced jack; related to ground).
This signal can be routed to a poweramp
or a FX device via a shielded cable.
25
LINE OUTPUT: LEFT
Line Out for the preamp's left channel (1/4"
unbalanced jack; related to ground).
This signal can be routed to a poweramp or a
FX device via a shielded cable.
26
LINE LEVEL
This control feature determines the level of
the LINE outputs (22), (23), (24) and (25). The
output signal can be amplified to 15 dB if
required.
27
FX LOOP RETURN: RIGHT
Signal input right stereo channel for the FX
Loop. Connect this input to a signal
processor’sright output/send jack via a shielded
cable with 1/4" plugs.
28
FX LOOP RETURN: LEFT
Signal input left stereo channel for the FX Loop.
Connect this input to a signal processor’s left
output/send jack via a shielded cable with 1/4"
plugs.
29
MONO OUTPUT; FX LOOP SEND
Output for patching the preamp signal to a
poweramp input or the input of a another
preamp or signal processor/FX device.
Ensure you use a shielded cable for this signal
circuit.
When the preamp is active, the MONO output
(29) and the INSTRUMENT output (30) provide
a signal that is very similar to that of a guitar´s
pickups, and at much the same level. You can
use the two volume knobs to dial in the desired
level very precisely. Although this might seem
pretty mundane, this feature is essential when
you´re using the bypass circuit. Usually, you
want to establish the same conditions for the
sound shaping device following the Tube Toner
in your setup (e.g. to ensure the signal you are
sending to an effects device or the next preamp
in serial setup has the same level).
INPUT
Unbalanced 1/4" (main) input jack.

TIP Stereo FX loop:
You can connect a signal processor between
the MONO OUTPUT (29) and the FX LOOP
RETURN jacks (27) and (28) or directly between
the LINE OUTPUTS (24) and (25) and a stereo
poweramp's inputs. There is a substantial
difference between these two applications:
When you connect the Processor to the FX
LOOP, the send signal is identical to the guitar
signal when the Tube Toner is in Bypass mode
and the preamp signal when the preamp is
active. The send level only is influenced by the
settings of the volume controls in this case.
The level of the master output signal routed to
the LINE outputs can be increased via the
LINE LEVEL (26) pot.
However, when you connect the Processor
between the LINE outputs and the poweramp,
the input (Send) signal to the FX device can be
increased via the LINE LEVEL (26) pot and you
have two Send signals (left, right) available.
This option is recommended for low impedance
(0 dB) FX devices that are not equipped with a
variable input.
If you chose to use this option, you should
ensure that the output signal of the effects
device has a level sufficient (preferably variable)
to drive the power amp. For another
conceivable option, you could patch an effects
device or stomp box/pedal between the
INSTRUMENT (30) output and the input of a
combo.
