In odu ion
Congratulations on your purchase of the Mission
VM-1 volume pedal. This product is designed to be
intuitive to setup and operate, and to provide many
years of trouble free service.
However, we recommend that you take a few
moments to read through this User Guide in order
to get the best possible experience with your new
pedal.
f tur
The VM-1 is a professional quality, all metal volume
pedal designed for use with guitars. The pedal uses
a 470K Ohm impedance potentiometer, that works
perfectly with most passive electric guitar pickups.
The VM-1 also features an isolated second output
for connecting to a tuner or similar device, and a
mute switch to permit silent tuning and noise free
guitar changes.
Pow
The VM-1 is a passive device and requires no
internal battery or external power source for volume
control and switching. If your VM-1 is fitted with
the optional LED indicator, an internal 9v battery
is required to power the LED only. If the battery is
removed, the pedal will still function, only the LED
will be disabled. Replace the battery by opening the
battery cover on the baseplate.
ConnE ions
The VM-1 uses a single ¼” TS phone jack marked
IN, and two ¼” TS phone jacks marked OUT 1 and
OUT 2 on the underside of the pedal. Connect your
guitar directly to the IN jack with a regular guitar
cable.
Since the VM-1 is a high impedance pedal, it
works best when used first in the signal chain and
connected directly to the guitar output. In general
it is not recommended to use the pedal after other
effects, particularly buffered effects, as this may
cause an uneven response. Connect OUT 1 to the
guitar amp or next pedal in your signal chain.
If you are using a guitar tuner, you can isolate it
from the signal chain by connecting it to OUT 2.
OUT 2 is only enabled when the pedal is in mute
mode. This avoids the tuner and additional cabling
loading the pickups and causing a loss of high
frequency sometimes referred to as ‘tone suck’.
mutE modE
Mute mode is engaged by pushing on the front of
the pedal to activate the switch under the rocker. In
mute mode, OUT 1 is disconnected so no signal will
pass to the amplifier. This is useful to completely
mute your signal when the instrument is not in use,
and allows switching of instruments on the input
without any clicks or pops. OUT 2 is engaged in
mute mode in order to allow silent tuning. Activating
the switch a second time will reconnect OUT 1 and
disconnect the tuner. If fitted, the optional LED will
light when in mute mode.
Adju mEnts
The tension of the rocker can be adjusted using the
tension adjustment screw on the rear of the pedal
between the rocker and the base. Use the hex key
provided to tighten the adjustment screw until the
pedal remains in place. It maybe necessary to adjust
this screw every once in a while to compensate for
use and environmental conditions such as very hot or
cold weather, when the pedal has been stored for a
long period, or after shipping. Replacement hex keys
are available from Mission Engineering. The tension
adjuster is not included if the optional spring load has
been fitted.
The switch sensitivity on the VM-1 can be adjusted
by lowering or raising the switch in the chassis.
Use spacers and washers provided to lower the
switch making it harder to press. Remove spacers
and washers to raise the switch making it easier
to press. When replacing the switch, be careful
not to over tighten the lock nut and damage the
switch.
