Tefi Vintage Lab GEGÈ User manual

Te Vintage Lab is pleased to welcome you to our family. We hope you
enjoy using our new Gegè germanium fuzz. 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!
Gegè - Germanium fuzz
The oldest distortion effect of them all is revisited by TEFI Vintage
Lab in an original concept that merges NOS germanium transistors,
essential for their sonic characteristics, in a new design to get a wide
variety of modern and dynamic fuzzy sounds. From light dynamic
growl to angry uncontrollable distortion.
Despite being one of the simpliest TEFI designs, a year and half was
spent in research and development to get original sonic results, whe-
ther using Single Coil or Humbucker tted guitars.
We suggest placing Gegè as a rst pedal in an effects chain, or after
other True-Bypass equipped pedals only, because its typical sonic
characteristic is linked to direct interaction between the guitar’s pi-
ckup and Gegè’s non-linear amplitude variable low input impedance.
Interposing buffered pedals between a guitar and the Gegè Fuzz will
not damage it in any way, but its original sound will be considerably
altered.
Caution! Do not connect Gegè Fuzz in a common ground multiple output power supply
(daisy chain)!
The Gegè’s internal circuit uses PNP germanium transistors and, unlike to the more commonly
used negative ground pedals, the circuit’s ground is connected to the positive terminal (“posi-
tive ground”). If you connect Gegè to a common negative pole ground multiple output power
supply (daisy chain), the positive ground of Gegè shorts to the negative ground of the power
supply, causing malfunction and possible damage.
You must use a 9V stabilized battery, a stand-alone or a galvanic insulated ground multiple ou-
tput stabilized power supply only.
TEFI Vintage Lab is not responsible for damage or malfunction due to power connection mista-
kes, or by using inappropriate power supply sources that do not respect the specications and
warning stated above.

TECHNICAL SPECIFICATIONS
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.
• 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 enclo-
sure compartment located under the footswitch. Be careful not to damage
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operating: connect a 9V stabilized external power supply
adapter to the pedal’s power connector located on the right side (5.5mm
connector with 2.1mm pole type). Do not reverse polarity! (external posi-
tive, internal negative). In the presence of reversed polarity the pedal will
not power up; no damage will be caused below 25V reversed polarity.
CAUTION! Do not connect Gegè Fuzz in a common ground multi-
ple output power supply!
CONTROLS AND FUNCTIONS
GAIN: controls the amount of gain and fuzz distortion. It is a wide range con-
trol that allows ne calibration of overall distortion, whether using Single Coil
or Humbucker pickups.
VOLUME: controls the post-distortion output level and can considerably ex-
ceed the signal bypass level to achieve Solo boost.
TONE: controls highs to get either a warmer or brighter sounds.
Toggle switch Natural/Broken Speaker:• In “Natural” position Gegè de-
livers a “Classic” easy-to-use Fuzz effect. In “Broken Speaker” position it
gives a very dirty and “grating” sound that resembles a damaged speaker
cone or a Bass/Baritone Sax-like tone, useful also for Garage/Beat style.
Toggle switch Fuzzy/Fatty:• controls the amount of the bass tones. In
“Fuzzy” mode it gives a bright sound, while in “Fatty” mode it provides
more mid-bass amount giving a very fat sound.
Dynamickiller:• Gegè has an internal dip-switch command, located betwe-
en the two germanium transistors. With Diynamic Killer function you can
choose the amount of distortion compression in the presence of a very
strong input signal. In the “Off” position it provides heavy compression,
with large attack signals; set to “On” to get more dynamics. The Dynamic
Killer has more effect on guitars equipped with high-output Humbucker pi-
ckups and it has low/no inuence on Single Coil pickups. We recommend ca-
reful adjustment of the dip-switch, with a small screwdriver. Disconnect the
power supply and the Input jack before carrying out any modications.
