Release the switch and the FX led will start blinking.

If you want to erase the footcontroller memory press the 

switch #5. To keep the memory press any of the #1 to #4 

switches. Please note that once the memory is erased it 

cannot be recovered.

Release the switch and the footcontroller will synchronise 

with the amplifi er.

The factory default is as follows:

FSW #1: Clean/Mid Shift

FSW #2: Crunch Mode

FSW #3: OD1 Mode

FSW #4: OD2 Mode

FSW #5: Master

FSW #6: Gate

Hints

Hint 1: It is possible to use different modes in the same 

channel with different volumes to avoid imbalance which 

can be especially interesting in the Clean channel. To do 

this simply create 2 presets in the footcontroller assigning 

MASTER 1 or MASTER 2 to any of the modes.

If  you  do  not  connect  any  effect  to  the  programmable 

SERIAL FX LOOP the RETURN LEVEL control can be used 

to act like an extra volume control in any of the channels.

Hint 2: To have a tuner output muting the amplifi er, connect 

the tuner to the FX send and select the Clean channel. Turn 

the RETURN LEVEL control to CUT and switch the FX loop 

on. Store this preset as described before and label it for 

example as ‘tuner’. Obviously in this confi guration it is not 

possible to connect any other effect to the loop. 

Hint  3:  To  use  a  different  preamplifi er  and  combine  it 

with the JVM channels, connect the external preamplifi er 

output to the Programmable Serial loop return and turn the 

RETURN LEVEL to desired external preamp level. Connect 

the external preamp input with a splitter to the amplifi ers 

input (it might be necessary to use an active splitter to keep 

a high impedance and/or an isolated one to avoid ground 

loops). Switching the effects loop ON and OFF will alternate 

between the external preamp and the JVM preamp.

Hint  4:  Notes  about  using  2  heads  simultaneously.  The 

suggested  procedure  is  connect  the  ‘master’  head 

PREAMP  OUT  to  the  ‘slave’  head  POWER  AMP  IN  and 

switch the POWER AMP INSERT to ACTIVE in the ‘slave’ 

amplifi er. 

In order to track the master volume settings in both heads 

(as  the  master  volume  circuitry  is  wired  after  the  loop)  it 

is  suggested  to  use  MIDI  control  with  both  amplifi ers 

programmed in the same way. Connect the MIDI IN of one 

of the amplifi ers to the MIDI THROUGH of the other and 

the pedalboard or MIDI equipment to the remaining MIDI 

IN.

The  JVM  range  features  a  fully  confi gurable 
footcontroller.  Connection  to  the  amplifi er 
requires  a  standard  mono  1/4"  jack  to  jack 
cable. Any guitar lead will work and practically 
there should be no limit in its length. 

When the front panel FOOTCONTROLLER / MIDI PROGRAM 

switch is off, the footcontroller operates in safe mode and 

executes the commands the moment the switch is pressed 

down. 

If  you  enter  the  FOOTCONTROLLER  PROGRAM  mode 

(LED red) you will be able to program the footcontroller but 

nevertheless the footcontroller and the amplifi er will remain 

fully operational with the only difference that the commands 

will  be  executed  when  releasing  the  footcontroller’s,  as 

opposed to the normal mode. 

Each  of  the  individual  footcontroller’s  has  2  modes  of 

operation: 

preset store and switch store

In 

preset  store  mode,  any  of  the  footcontroller’s  can  be 

confi gured to store the current amplifi er status. The current 

channel, master, FX and noise gate status will be stored and 

recalled when the respective footcontroller is pressed.

To store the current status simply:

Set the amplifi er to FOOTCONTROLLER PROGRAM mode 

(red light ON).

Press and hold the desired switch for about 3 seconds. 

The  FX  footcontroller  LED  will  fl icker  a  couple  of  times 

indicating that the preset has been stored. 

In 

switch  store  mode,  any  of  the  footcontroller’s  can  be 

confi gured  to  replicate  the  front  panel  switches  and  the 

amplifi er  will  react  exactly  in  the  same  way  as  when  you 

operate them on the front panel.

All  the  front  panel  switches  can  be  mapped  to  any  of  the 

footcontrolleres  without  any  limitation.  The  only  exception 

is  the  FOOTCONTROLLER  /  MIDI  PROGRAM  key  which 

cannot be assigned to the footcontroller. 

To  assign  any  of  the  front  panel  keys  (except 

FOOTCONTROLLER  /  MIDI  PROGRAM)  to  any  of  the 

footcontrolleres simply:

Set the amplifi er to FOOTCONTROLLER PROGRAM mode 

(red light ON).

Press and hold the desired footcontroller. 

While holding the footcontroller down, in less than 3 seconds, 

press the front panel switch you want to map. 

The  FX  footcontroller  LED  will  fl icker  a  couple  of  times 

indicating that the switch has been mapped. 

From now on the selected footcontroller will act exactly in the 

same way as if you press the related front panel switch. 

Keys and presets can be assigned as wished without limitation 

and in any order (again, except the FOOTCONTROLLER / 

MIDI  PROGRAM  key).  The  footcontroller  confi guration  is 

stored in the footcontroller itself, not in the amplifi er. Resetting 

the amplifi er will not affect the footcontroller confi guration as 

well.

The  footcontroller  can  be  hot-swapped  and  synchronises 

itself  with  the  amplifi er  after  connection.  However  it  is 

recommended  to  connect  the  footcontroller  lead  to  the 

footcontroller side fi rst and then connect it to the amplifi er. 

MIDI operation

Pressing the FOOTCONTROLLER / MIDI PROGRAM switch 

twice puts the amplifi er in MIDI waiting mode, the LED will 

fl ash until a valid MIDI program change command is received. 

On  reception  of  a  MIDI  program  change  command  the 

amplifi er stores the current status (C FX + Noise Gate 

+ Master Settings) in the MIDI program number received. It is 

possible to store up to 128 different MIDI presets. 

To  exit  this  status  without  waiting  for  incoming  MIDI  data 

press  the  FOOTCONTROLLER  /  MIDI  PROGRAM  switch 

again.

Note  about  MIDI  channels:  By  default  the  amplifi er  is 

confi gured to listen to MIDI channel #1 but it can be changed 

to listen to any of the 16 MIDI channels as follows:

Switch the amplifi er off (Power switch, not Standby).

Press and hold the FOOTCONTROLLER / MIDI PROGRAM 

switch.

Switch the amplifi er on (Power switch).

Release the FOOTCONTROLLER / MIDI PROGRAM switch, 

the LED will start to fl ash.

Send ANY MIDI command using your MIDI pedalboard or 

any other MIDI equipment.

The amplifi er will detect which channel came in and confi gure 

itself to listen to that MIDI channel only. From now on any 

MIDI preset you had previously stored will be activated only 

on  the  new  channel  regardless  of  what  channel  you  used 

before, this allows a fast reconfi guration should there be a 

MIDI confl ict with any other outboard equipment. 

If you want to exit the MIDI channel selection without any 

action  press  the  FOOTCONTROLLER  /  MIDI  PROGRAM 

switch while waiting for MIDI data.

Footcontroller Reset:

It is possible to reset the footcontroller to the factory default 

status. This is achieved as follows:

Unplug the footcontroller at any of the cable sides.

Press and hold the switch #6 (right switch).

Plug in the footcontroller cord.
