Electro-Harmonix - XO Holy Stain
Righteous multi-effect possibilities emerge when Reverbs, Pitch Shifting and celestial Tremolo meld with pure analog Drive and Fuzz. The brilliance of the Stain lies in the dynamic interaction of its controls – create novel tonal metaphors. Stain the hearts of your fans!
The Distortion section of the Holy Stain
is made up of 4 controls: DIRT,
COLOR, TONE and
VOLUME. DIRT and COLOR are both
rotary switches while TONE and
VOLUME are rotary
The DIRT control allows you to change
the type of distortion from Clean to
Fuzz to Drive.
The Drive setting gives you a smooth
distortion. The Fuzz setting is a harder
compared to the Drive setting. Use the
Clean setting to bypass the distortion.
Please note: the
Clean setting is part of the distortion
circuit so you may still hear a little grit
when set to Clean.
The Holy Stain has two controls to
help tailor your distortion’s tone:
COLOR and TONE. The
COLOR switch subtly changes the
character of the distortion using three
Dark and Warm. Use the Bright setting
for a full frequency distortion. Choose
the Dark setting
to cut high frequencies for a smoother
distortion. The Warm setting is
somewhere in between
the other two giving a rounder
distortion. Please note: when DIRT is
set to Clean, the COLOR
switch has no effect on the tone except
that in Warm mode your sound may be
distorted, depending on the volume of
your pickups. The TONE knob is a
drastic tone control
that, when set to extremes, will allow
you to emphasize the highs or lows.
Set TONE to the
middle for a nice, even, full frequency
The VOLUME control sets the overall
output volume from the distortion
stage. The output of
the distortion stage is sent directly into
the input of the DSP.
ROOM and HALL REVERB
The two reverb settings are excellent
sounding, easy-to-use reverbs. The
between the Room and Hall reverbs is
the pre-delay time. The Hall setting
has a longer predelay
as compared to the Room. Pre-delay
is the delay time between playing a
hearing the onset of the reverb effect.
All four DSP functions allow you to
change their sound using the
AMOUNT knob. The
AMOUNT knob’s function changes
with each setting. For the two reverbs:
knob sets the reverb time or length of
reverb tail. As you turn the AMOUNT
the reverb time will increase.
The MIX knob sets the balance
between the output of the distortion
circuit and the output of
the DSP. When the MIX knob is set to
fully counter-clockwise you will hear
no DSP. When the MIX knob is set fully
clockwise you will hear the direct
output of the DSP
which may include the distortion that is
present at the DSP’s input.
Press the MODE Footswitch to cycle
through the 4 DSP modes.
In Pitch Shift mode, the Holy Stain will
change the pitch of the note you play
up to a 3rd and
down to a 4th. This means that when
the AMOUNT knob is set to the full
clockwise position, if
you play a C note on the guitar, the
Holy Stain will shift that note up to an
E. If the AMOUNT
knob is set to full counter-clockwise,
the Holy Stain will shift the C note
down to a G.
In Pitch Shift mode, the AMOUNT knob
sets the pitch shift amount. When
AMOUNT is set to
12 o’clock, you will hear practically no
pitch shift. As you turn the knob in the
direction, your notes will shift up. As
you turn AMOUNT counter-clockwise
your notes shift
down. The AMOUNT knob, in Pitch
Shift mode, is continuously variable
from – a 4th to + a
3rd. It does not change the pitch in
discrete steps. Set the AMOUNT knob
around 12 o’clock to double or thicken
your sound without changing the pitch.
The MIX knob controls the volume of
your original note versus the volume of
the pitch shifted
note. To hear an equal balance
between original and pitch shifted
notes, turn the MIX knob to
12 o’clock. To hear only the pitch
shifted notes, turn MIX to its fully
The Tremolo effect in the Holy Stain is
a simple tremolo effect with some
reverb thrown in.
As you turn the AMOUNT knob
clockwise, the rate of the tremolo effect
will quicken and the
amount of reverb will increase.
The MIX knob controls the depth of the
Tremolo effect. As you turn the MIX
you will hear more Tremolo. Turn the
MIX knob to its maximum setting for
