User Manual

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 knob
clockwise you will hear more Tremolo. Turn the MIX knob to its maximum setting for
maximum Tremolo.
- CONTROLS -
DIRT Switch – Switches between CLEAN, FUZZ and DRIVE. Use this switch to change
the type of distortion. Set it to CLEAN to bypass the distortion.
COLOR Switch – Switches between BRIGHT, DARK and WARM. Use this switch to
make subtle changes to the character of your distortion. Please note: when DIRT is
set to CLEAN, the WARM setting of the COLOR switch may produce some distortion.
TONE Knob – Use this control to drastically change the sound of your distortion. As
you turn the TONE knob counter-clockwise from its middle position, the bass
response will increase and treble will decrease. As you turn the TONE knob clockwise
from the middle, the treble response will increase and bass will decrease. Turn TONE
to the middle position to obtain an even frequency response.
VOLUME Knob – Sets the output level of the distortion stage. As you turn the
VOLUME knob clockwise, the volume will increase.
AMOUNT Knob – Controls the DSP parameters. The function of this knob changes
for each DSP setting:
DSP Function AMOUNT Parameter
Room Reverb Reverb Time
Hall Reverb Reverb Time
Pitch Shift Pitch Shift Amount: - 4th to + 3rd
Tremolo Tremolo Rate
MIX Knob – This control sets the balance between the output of the distortion and
the output of the DSP. The counter-clockwise position will yield 100% distortion. The
clockwise position will yield 100% DSP. When the DSP is in Pitch Shift mode, set the
MIX knob to 12 o’clock to hear an equal balance of your original note and the pitch
shifted note. In Tremolo mode, the MIX knob acts like a Depth control for the
Tremolo effect. The more you turn MIX clockwise the more tremolo you will hear.
STATUS LED and BYPASS FOOTSWITCH – The BYPASS Footswitch toggles the Holy
Stain between Effect and True Bypass modes. When the STATUS LED is lit, the Holy
Stain effect is active, when the STATUS LED is off, the Holy Stain is in True Bypass
mode.
MODE FOOTSWITCH and LEDs – The MODE Footswitch cycles through the 4 DSP
effects in the following order: Room Reverb, Hall Reverb, Pitch Shift, Tremolo, Room
Reverb, etc. When you first apply power to the Holy Stain, it will start in the Room
Reverb setting and the ROOM REVERB LED will be lit. If you then press and release
the MODE Footswitch, the Holy Stain will switch to Hall Reverb and the HALL REVERB
LED will light. Continue to press and release the MODE Footswitch to cycle through
the rest of the DSP effects.
INPUT Jack – This ¼” jack is the audio input to the Holy Stain. The input impedance
presented at this jack is 100kΩ.
OUTPUT Jack – This ¼” jack is the audio output from the Holy Stain. The output
impedance at this jack is 570Ω.
EXP. PEDAL Jack – This ¼” input accepts an Expression Pedal with TRS connection.
The Expression Pedal takes over the AMOUNT knob so that you can modulate the
DSP effects with your foot. To obtain the full range of the AMOUNT knob with the
Expression Pedal, set AMOUNT to 12 o’clock. To change the range of the Expression
Pedal, try different settings for the AMOUNT knob. Some acceptable Expression
Pedals include: Boss FV-500L, Alesis F2, Roland EV7, Moog Music EP2, Roland EV5
and M-Audio EX-P.
9V Power Jack – Plug the output of the Holy Stain’s supplied AC Adapter into this jack
located at the top of the Holy Stain. The Holy Stain requires 9VDC at 100mA with a
center negative plug. The Holy Stain accepts Boss style AC Adapters.
- WARNINGS -
To achieve its incredible distortion, the Holy Stain has a very high maximum gain.
This requires that both the pickups and cables be well shielded and properly
grounded to avoid excessive hum and stray oscillations when the FUZZ and DRIVE
settings are used.
