Effect modules

The MRC-90-LOOP is built up of 7 (effect) modules. Each module can be regarded as a single unit.

CAB
The MRC-90-LOOP has a speaker simulation with 72 variations.
Adjust the overall volume with the “VOLUME” knob.
By combining the two CAB controls, you select the individual speaker models.

Sequence number	Speaker
OFF	No speaker simulation
A1-A9	Mshall 1960AV V30
B1-B5	Spring Pro Junior 1×10
B6-B9/C1-C2	Spring Champ 25 SE 1×12 against Wall

SPACE (DELAY/REVERB)
The MRC-90-LOOP has 9 DELAY or REVERB settings.

Effect	No	Name	Description
Reverb	1	HALL	Simulates a wide environment and thus long reverberation
	2	ROOM	Simulates a small room with relatively many soft reflections
	3	ECHO	Simulates an echo effect such as in the mountains
	4	TILE	Simulates very strong reflections, e.g. in the bathroom/laundry room
	5	DUCKING	Simulates reverb with NoiseGate. Only slight reverb when playing but strong reverb tail when stopping.
Delay	6	CLEAN	Original sound with delay effect
	7	DYNAMIC	Delay effect is lowered while playing. This prevents fast phrases from becoming muddy.
	8	TAPE	Simulates a tape echo
	9	REVERSE	Reverse Delay

MOD(CHORUS/PHASER)
The MRC-90-LOOP features a CHORUS and a PHASER effect. Both are analog effects that can be activated separately within the MOD effect.
CHORUS
The CHORUS effect in the MOD module can be deactivated/activated with the CHORUS toggle switch.
The DEPTH knob adjusts the range of the CHORUS effect.
The RATE knob affects the speed of the CHORUS effect.
LEVEL adjusts the output signal level of the effect.
PHASER
The PHASER effect in the MOD module can be deactivated/activated with the PHASER toggle switch.
The SPEED knob affects the speed of the PHASER effect.
LEVEL adjusts the output signal level of the effect.

DISTORTION

The MRC-90-LOOP features a british-style DISTORTION effect. Two different characteristics can be selected via the SPICE selector switch.
The GAIN control adjusts the amount of distortion.
TONE is used to adjust the tone of the DISTORTION effect.
LEVEL adjusts the output signal level of the effect.
OVERDRIVE
The MRC-90-LOOP has an analog OVERDRIVE, which is based on the famous original from Japan.
The GAIN control adjusts the amount of distortion.
TONE is responsible for the tone control of the OVERDRIVE effect.
LEVEL adjusts the output signal level of the effect.
BOOST
The MRC-90-LOOP has a module for BOOST and SOUND CONTROL. The analog effect can provide up to +15dB signal strength boost.
Use the toggle switch BOOST to activate the BOOST module.
The GAIN control adjusts the signal boost.
BASS and TREBLE are used to control the tone.
LEVEL adjusts the output signal level of the effect.
LOOPER
The MRC-90-LOOP has a LOOPER with 9 LOOP phrases with a maximum storage capacity of 10min. The basic functions of the LOOPER can all be operated by the foot switch (5).
The signal strength of the played LOOPER signal can be adjusted with the VOLUME knob.
When the VOLUME knob is lit in red, this indicates that there is already music data on the selected LOOP phrase.
The following actions apply when the LOOP phrase is empty:

Recording and playback

2	Double click on LOOP button	No LEDs	PAUSE
3	Hold the LOOP button for 2 seconds	No LEDs Volume control not lit	All data of the phrase deleted

Switching between LOOP phrases
The 9 separate LOOP phrases can each be operated as described above. To switch to the next LOOP phrase, press buttons 1+2 simultaneously for 2 seconds. To go backwards, press buttons 3+4 simultaneously for 2 seconds.

LIVE/PRESET mode

The MRC-90-LOOP has two different operating modes.
By briefly pressing the two buttons 2+3, you can switch between the two operating modes.
LIVE Mode
In LIVE mode, the MRC-90-LOOP acts like a pedalboard with 7 effects that can be used separately and combined as desired.
PRESET mode
In PRESET mode, different effect combinations can be stored in four memory locations.
Note: PRESET mode only stores the on/off state of the four effect modules (DELAY/REVERB + CHORUS/PHASER + DISTORTION + OVERDRIVE). Their individual effect parameters as well as the settings of LOOPER, CAB and BOOST are not stored.
With the help of the PRESET mode, fast and comfortable switching times can be realized, e.g. during performances or for recording sessions, even during individual songs.
Saving a Preset
Switch to LIVE mode.
Activate one or more effect modules that you want to use.
Press and hold one of the foot switches 1-4 until the respective LED starts flashing.
The preset is now stored. Four memory locations (A-D) are available.
Recalling a Preset
Switch to PRESET mode.
Tap the respective footswitch (1-4) whose previously stored PRESET you want to recall.

TUNER

The MRC-90-LOOP has a built-in pedal TUNER.
Press both footswitches 2+3 simultaneously for about 3 seconds to activate TUNER.
The output signal is muted and the display switches to TUNER mode.
Now play a single empty string. The tuning tone is now shown in the display. At the
top of the display, several LEDs indicate the tuning status.
Blue LED in the middle at the top of the display -> tuning tone reached
Red LEDs on the left side -> tuning pitch too low
Red LEDs on the right side -> tuning pitch too high
