Tefi Vintage Lab BUBOP! User manual

TEFI Vintage Lab is pleased to welcome you to our family. We hope
you enjoy using our new BuBoP! Buffer/Booster. 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!
BuBoP! - Buffer, Booster and Presence!

BuBoP! was conceived by merging three features very often needed
by musicians: Buffer (the quiet Joe Buffer) and Booster (the angry
Don Booster) combinable with Presence (the fat Bill Presence). This
handyman stompbox can be placed anywhere in the effects chain: e.g.
before an overdrive pedal to get more saturation, before a fuzz box to
radically change its sound behavior to get a lot of “angrier” distortion.
You can also place BuBoP! at the end of the chain to get the level boost
required for solos or simply to give get overall sound equalization.
It’s also useful to adapt the correct load instrument impedance to a
old vintage amplier or effects with low input impedance levels, or
else before low input impedance mixers and PC soundcards. Thanks
to its wideband response, covering the whole audio spectrum, BuBoP!
can also be used with a bass guitar, electric piano or any instrument
needing a preamplier and/or equalization that can be activated with
the Presence switch. The original “clip guard” LED blinks when the
input signal is too high: this is an useful alert to establish whether the
amp is saturating or not. With a blinking LED the BuBoP! gain stage
saturates and can produce overdrive tones.

CONNECTION AND USE
• Connection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 battery
compartment located between the two footswitches. Be careful not to da-
mage 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 right side (5.5mm connector
with 2.1mm pole type). Do not reverse polarity! (external positive, inter-
nal 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
Buffer or Booster modes are selected by pressing the footswitch located on the
right side of the pedal faceplate. The Presence function is activated by the “P”
toggle switch and is operative only when the Booster section is enabled.
BUFFER: is a unity gain amplier (input and output levels are the same)
used to adapt the high load impedance required from a guitar or passive bass
to mid-low input impedance devices. A buffer must always be placed before
most mixers, audio adapters or vintage equipment, to avoid input attenuation
and a degraded instrument response (lack of mid-high frequencies). For the
same reasons, it can placed before a long instrument cable to null the parasitic
cable capacity effect. Buffer section uses discrete components and is class-A
operating.
BOOSTER: this section increases the signal level without causing distortion.
Placing BuBoP! before an overdrive effect increases sustain and compression.
It can also be placed before a fuzz box to signicantly change its sound obtai-
ning schizophrenic distortions. However, it can also be placed after the effects
chain to increase the overall output level, e.g. during solos. Its wideband re-
sponse will not affect the instrument or previous effects chain response. The
“Level” knob sets the Booster gain from 0dB to +18dB.
PRESENCE: this section is activated by the “P” toggle switch and only works
when the Booster is enabled (turning to Buffer mode disables Presence).
There are two knobs for this mode:
increases a large portion of mid-high frequencies to obtain more instrument•
Presence without unpleasant “scratchy” effects. Hi Boost MAX (knob HI-
Boost full CW, knob LO-Boost full CCW)): +20dB @10kHz, turnover +3dB
@700Hz.
increases low frequencies to reinforce instrument response. LO Boost MAX•
(knob LO-Boost full CW, knob HI-Boost full CCW): +17dB @55Hz, turnover
+3dB @950Hz.
