Tefi Vintage Lab Smilin’ Ghost User manual

TEFI Vintage Lab is pleased to welcome you to our family. We hope
you enjoy using our new dynamic Tremolo/Percussion Repeater The
Smilin’ Ghost. Feel free to get in touch for any suggestions or clari-
cations as to how you might best use the effect. Play music and enjoy
using our products!
The Smilin’ Ghost
The Smilin’ Ghost is a versatile Tremolo and Percussion Repeater ef-
fect with a special dynamic control. Completely analog, it is equipped
with an opto-coupler (OCR), selected on our own specications, dri-
ven by our special wide range LFO. Thanks to a band frequency re-
sponse, The Smilin’ Ghost will not affect or change the original sound
of any instrument. Achievable effects range from a classic sweet Tre-
molo, with an LFO wave selectable, to the Percussion Repeat, an ef-
fect conceived during the 60s in electronic organs to emulate the fast
Pizzicato of a Mandolin, but denitely useful for any kind of electric
instrument.
A special proprietary circuit, called T.R.F.I. (Touch Response Fade In)
allows proportional dynamic control of the effect, depending on the
dynamics used by the musician during the playing of a melody line or
a rhythmic pattern.
T.R.F.I also solves the frequent problem that can occur when the Tre-
molo is activated where the attack melody is “eaten” when the OCR
closes. Combined with an electric piano, the T.R.F.I. function allows
you to discover previously unexplored musical territory.

CONNECTION AND USE
• Connectingtoinstrumentandamplier/gear: connect your instrument
(or gear effects chain) to the Input jack on the pedal’s right side with a
6.3mm Jack instrument cable. Connect the output jack on the pedal’s left
side to an amplier (or to the next effects in your chain) with a 6.3mm Jack
instrument cable.
• ExternalSpeedControl: connect with a stereo 6.3mm Jack to an expres-
sion pedal potentiometer congured, 50 kOhm or 100 kOhm internal poten-
tiometer. Other potentiometer resistance values (minimum resistance va-
lue >= 10 kOhm) will not damage the effect, but the pedal expression “feel”
is not optimized.
• T.R.F.I. remote On/Off: connect to a bi-stable or momentary pedal
switchasrequired.
• Battery: to access the battery compartment, remove the four screws on
the bottom cover. Connect the 9V battery (6LF22 type) to the battery clip
connector. Do not reverse the polarity! Insert the battery into the battery
compartment located between the two footswitches. Be careful not to dama-
ge the wires and/or the battery clip. To preserve battery life, disconnect the
instrument cable from the pedal Input jack when the pedal is not in use.
• Powersupply: connect a 9V stabilized external power supply adapter to the
pedal’s power connector located on the upper-right side (5.5mm connector
with 2.1mm pole type). Do not reverse polarity! (external positive, internal
negative). In the presence of reversed polarity the pedal will not power up;
no damage will be caused below 25V reversed polarity.
CONTROLSANDFUNCTIONS
Tremolo or Percussion Repeat mode is selected by pressing the footswitch lo-
cated on the right side of the pedal faceplate. The active function is displayed
by the related blinking led.
SPEED knob: controls the LFO speed modulation in Tremolo or Percussion
Repeat mode. The frequency range of the LFO can be adjusted from 0.7Hz to
15Hz. You can also control the modulation speed by connecting an external
expression pedal via a 6.3mm stereo Jack cable. When an expression pedal is
in use, the Speed knob is disabled.
BLEND knob: controls the balance between the direct (dry) and effected
(wet) signal.
SENSknob:this knob controls the T.R.F.I. threshold depending on the instru-
ment’s instantaneous signal level. Enable T.R.F.I. via the toggle switch or a
remote switch pedal, set the Blend knob to the middle position or more CW and
initially set Sens knob all CCW. While playing a note or chord, slowly rotate the
Sens knob until the modulation stops: the Blue LED will light up, indicating
that T.R.F.I. is working. At this point you can newly set the Sens knob to obtain
the desired delayed releasing of T.R.F.I. and consequently the effect’s return,
based on playing dynamics. Playing louder will stop the modulation, while
playing more softly will cause the modulation to gradually return.
Toggleswitch“T.R.F.I”: enables the T.R.F.I. effect. When activated, a slight
luminescence is noticeable on the LED at the center of the faceplate between
the T.R.F.I. knob and the toggle switch.
Toggleswitch“Waveform”: in Tremolo mode, this command selects the en-
velope waveform, either sine or square.
Toggle switch “Percussion Lenght”: selects the decay envelope of Percus-
sion, regardless of the speed of the LFO. Set to “Short” to obtain quick decay
percussion, set the “Long” position to get a longer decay envelope, similar to
the renowned Percussion Repeat effect installed in many old Farsa Organs.
Percussion Repeat in combination with T.R.F.I. also works well with an electric
piano.
