overview

As its name indicates it, the Fuzz Ultra is to be classified in the family of Fuzz.

The Fuzz effect describes the sound obtained by the clipping of the
signal which presents a wave of square shape. A sensible choice of
components gives to this Fuzz a particular, at the same time vintage
and modern, texture.

The Fuzz has a high gain.

It has a volume control, a tone control and a drive control. It also has a
Gate control that eliminates noise. Gate setting provides various effects
such as staccato or pumping.

A three position switch allows you to select the appropriate timbre on
the guitar in use. Fuzz also has a Fat mode and a Ultra mode that bring
big bass making its use with a bass guitar particularly interesting.

Like all Labo ★ K Effects pedals, the Fuzz Ultra is True By Pass. It

means that when the effect is not active, the device is completely disconnected
from the path of the signal and thus adds none résistive load in this one (The
accumulation of résistives loads on the path of the signal eventually decreases
the power and the brightness of the sound)

controls

I – THE POTENTIOMETERS

1. Volume

This control adjusts the output level of the Ultra Fuzz.
The normal volume range goes from zero to maximum unless the gate
is in action.

2. Tone

The tone control acts on the frequency range of the Fuzz.

3. Drive

This setting controls the rate of signal clipping.

4. Gate

This setting is the originality of the Fuzz Ultra. It offers a wide variety
of effects ranging from the Gate effect (mute in the absence of signal)
to the Pumping (compressor pumping style) over the staccato (mute
after the attack). When this setting is active, the volume control can no
longer mute. The start of the gate control allows to play on the signal
spectrum while increasing the gain of the Fuzz Ultra

II – THE SWITCHES

1. Timbre selector

Timbre selector with three positions Deep, Warm and Bright allows to
match the Fuzz Ultra and the type of microphone of the used guitar. It
also allows you to have multiple colors Fuzz.

2. Mode selector

Mode selector with three positions Fuzz, Fat and Ultra allows to have
three tone bandwidths.

! Fuzz mode works in the treble-mid band of traditional Fuzz.
! Fat mode boosts the bass giving more body to Fuzz.
! Ultra Mode provides big bass sounds making the use of the Fuzz

Ultra with a bass guitar very interesting.

Power supply

Labo ★ K Effects pedals are powered by 9V DC battery or external
power adapter using the « Boss ™ » standard (negative (-) in the
center, positive (+) outside.

The pedal can be supplied in several ways:

! 9V internal battery.
! AC Power adapter.
! AC Power adapter from another Labo ★ K Effects via « Power-

Link » cord.

! 9V battery from another Labo ★ K Effects pedal via « Power-

Link » cord.

Notes :

The power consumption of the Fuzz Ultra is 4mA what gives internal
battery a comfortable lifetime.
When the input jack is not pressed, the internal battery is
disconnected.
Change of the internal battery is done by unscrewing the four screws
on the bottom of the box.

power-link system

The Power-Link system of Labo ★ K Effects allows an external power
supply to power several Labo ★ K Effects pedals via the cable supplied
with each pedal by creating a daisy chain.

Using the Power-Link system of Labo ★ K Effects it is even possible to
power a Labo ★ K Effects pedal (or any other pedal using tne same
power standard) with the internal battery of a Labo ★ K Effects pedal.

The amperage of the power supply used must be higher than the total
consumption of pedals you want to feed simultaneously.

To respect the sense of connection, the Power-Link system uses 2
different connectors.

Lumberg connector J21 for the input.

Lumberg connector J25 for the output.

advices

To keep the integrity of the sound, use good quality mono Jack cords
exclusively.
To extend the life of the battery, remove the connector of the input
jack when not using the device.
Replace the battery when the light shines only weakly or not at all
during the use.
If an external adapter is exclusively used, it is recommended to
remove the internal battery.

Fuzz Ultra and wha-wha

Fuzz Ultra can be positioned either before or after a wha-wha pedal.
However Fuzz Ultra positioned before the wha-wha widens the sound
spectre of the wha-wha.

2.
If the sound does not comes out either in by pass mode, nor in effect
mode, go directly to the stage 4

STAGE 2

No audio ouput when the device is switched on :

! Verify that the output volume is not in zero position.
! · If the light shines correctly go to the stage 4.

STAGE 3

If the light shines weakly or not at all and the sound is weak and very
distorted:

! Change the battery or verify the connection of the power cable.
