FX Loop
The FX Loop can be used in serial or parallel mode (Pic. 1) 30. In serial
mode, the signal passes completely through the FX unit. In parallel mode,
the FX signal is mixed with the direct signal. Modulation effects, equal-
izers and compressors must be used in series in order to function properly.
Of course, the sound quality depends on the quality of the effects unit(s)
themselves.
There are some FX units, like Delays, with which you can control the ratio
of the effect level and the dry level yourself. These effects should then only
provide the pure effect sound, and be used in PARALLEL 30. This way,
AMP1
™
’s analogue tube sound will not be interrupted at any point,
resulting in optimal sound quality.
You can switch between serial and parallel modes by using the CUSTOM
CONTROL
™
30.
FX Loop Level
On AMP1
™
’s underside you will find a recess with a small pressure switch,
which enables you to switch the sensitivity between -10dB (for foot pedals)
and +4dB (for studio FX).
FX SEND 15
Effects Loop between the preamp and power amp. Connect the input of
your FX unit to this port.
FX RETURN 16
Connect the output of your FX unit to this port.
The FX Loop can be activated ort deactivated (bypass) via REMOTE1
™
or
MIDI1
™
.
Tip:
The FX Loop can be switched on and off, and presets can be saved, via
REMOTE1
™
or MIDI in. This way, you can activate the desired channel and
the FX Loop simultaneously.
If you are using a MIDI-enabled FX unit, you can change your effects pro-
gram via MIDI at the same time. For example, you can save a CLEAN sound
with chorus and reverb as a preset, or a dry, CLASSIC rhythm sound without
any FX, or a MODERN solo sound with delay, and each can be directly
recalled with one simple tap of the foot switch.

with a volume pedal
If you place an analogue volume pedal between SEND and RETURN, you can
use it to conveniently control AMP1
™
’s overall volume without changing the
basic sound. This is a very handy feature, especially when playing live onstage
(Pic 3.).
AMP1
™
with additional audio sources
A second instrument or audio source (for example an MP3 player) can be
connected to the RETURN port in parallel mode (Pic 4.).
AMP1
™
as a preamp
The Send port can also be used as a Line Out. Here you could, for example,
connect another power amp.
AMP1
™
as a power amp
The Return port also doubles as a Line In. Here, you can connect a preamp.
The input sensitivity can be switched from 200mV to 1 Volt by using the FX
Loop level switch on the bottom.
The power amp behaves like a tube amp, because the signal passes through
the tube. If using REMOTE1
™
, you can also use the PowerSoak function.
AMP1
™
as a boutique distortion pedal
You can go directly into a guitar amp from the SEND port. It is advisable to
set the amp to clean. You should also reduce AMP1TM’s Treble and Over-
drive volume, because the SEND signal has a very high output level (Pic 2.)
So you don’t overdrive the input, the FX Loop level on the underside of
AMP1
™
should be set to -10dB.
