AMPLIFIER SPECIFICATION
Caiman 5 00 is a full tube head amplifier, hand crafted by qualified craftsman. This amp
weighs not even 15 kilos and still has 50 Watts of power. The design of the amp, solves the
permanent problem of every musician - the handling. It is not only light weigh tube amp, but also
it’s all integrated in a very compact housing.
With its soft and compressed sound, it is the ideal amp for all ranges from Blues to Metal,
offering the comfort a musician is used to and expects from an amp. In preamplifier the classic
sound meets the modern. The EL84M tubes, used in power stage, are very dynamic, warm and,
which is more important, very reliable.
The Caiman has two switchable channels: clean and overdrive. Clean channel additionally
allows to reach a little crunch (especially with turning Master Volume off). With overdrive channel
though, you get tones from crunch to high gain. This channel also has two independent gain knobs,
switchable using footswitch. For instance: you can then set the Gain 1 at lower values and the Gain
2 at higher. So, when you want to play a solo, only thing you need to do, is to switch Gain 2 using
footswitch, like you usually do, when you change the channels. This will rapidly increase the amount
of gain.
Preamplifier was designed to increase functionality of equalizer section. The regulation depth
of each band allows to set many different tone types, which makes the Caiman extremely versatile
amp.
Switching between channels is possible using front panel switch or footswitch, which is
included in the set. Both channels have bright switches.
The Caiman has 4, 8 and 16 ohm outputs, so it’s possible to connect every type of cabinet,
but we have designed a special cabinet for it – 212 Caiman, which is compact and light weight.
The combo version 5 01 uses legendary Celestion G12T-75 internal speaker.

1. Cha el selectio
Switch to change channels of the
amplifier. It works only when Jack is
unplugged from the Footswitch socket.
In position “up” the clean channel is
on, whereas, in position “down” the
distorted channel is on.
2. Footswitch
Socket to
connect a
footswitch, with
controlled
Channel
switching and
Gain selecting.
TRS Jack socket
(T – tip:1, R – ring: 2, S – sleeve: ),
where tip changes channels, ring -
changes masters, sleeve is ground. It
uses “stereo” cable, which can be also
replaced by “mono” cable, however
then, the Gain switch will not be active
and, in the amplifier, only
potentiometer Gain 2 will be active.
3. I put
Input jack socket to connect to the
guitar.
4. Clea Volume
Volume of the clean channel.
HINT: At a low setting of this
potentiometer, you get a clean sound.
When you boost the clean
potentiometer, you get sound that is
more saturated until some crunch is
achieved. When you turn the Master
down and boost the Clean, you obtain
more crunch. So you can get crunch on
both channels, which, at the same
time, differ in character and dynamics.
5. Bright
High frequency boost for the clean
channel.
6. Gai 1
Gain control for the distorted channel.
HINT: With a little value you can
obtain crunch effect or overdrive. By
adding gain, distortion is added until
reading high gain. For guitars with
Humbucker pick-ups and high output
signal, it is possible, that turning the
knob to the right, does not cause more
distortion. It only gives more noise of
the amplifier. It is designed that way,
because each guitar has a different
output signal level, and the value of
gain was set up that way, that in the
case of guitars with less signal, it is
also possible to get more distortion.
7. Gai 2
Second gain control for the distorted
channel which is only available when
the footswitch is used.
This is a duplicate of Gain 1. They
both can be set independently and
selected with the use of a footswitch.
HINT: This potentiometer can be used
to boost distortion, e.g. while soloing.
To achieve such effect, set Gain 2 knob
in such a way that after switching from
Gain 1, the more distortion is heard.
8. Drive Volume
Distorted channel volume. Proportions
between clean and distorted channel
can be set by this potentiometer.
9. Bright
High frequency boost for distorted
channel. Apart from high frequency
boost, the switch also changes
distortion character. It is possible that
using certain controls of equalizer or
gain, high frequency boost will be less
noticeable.

10. Bass
Adjusts the low-frequency tone for
both channels.
11. Middle
Adjusts the middle-frequency tone for
both channels.
12. Treble
Adjusts the high-frequency tone for
both channels.
HINT: Set all the potentiometers in a
12.00 o’clock position, then adjust
them individually to get the best
sound. Remember, that the
frequencies of each controller are
related to each other, the change of
one influences the others.
13. Master Volume
Master volume control.
HINT: Besides controlling the volume,
it influences saturation of the clean
channel. Therefore, when turned down
to a lower level, a crunch sound can be
obtained on the clean channel.
14. Lamp i dicator
When glowing, the amplifier in on.
HINT: There is a 12V bulb under the
cover, which can be unscrewed without
taking the chassis out. If the light
needs to be replaced, turn the amplifier
off, unscrew the metal nut, gently push
the bulb in and turn left at the same
time until the bulb comes free from the
holder.
15. Sta d By
In position “up” the amplifier is ready
to work. Changing it to positions “ON”
sends anode voltage to the tubes – in
these positions the amplifier plays.
HINT: You should keep the switch in
the “up” position if there are long
breaks between playing. You should
also wait about 1 min. between
switching the Standby to the “up”
position and turning the amplifier off.
16. Power
This switch turns the amplifier on and
off. The amplifier is off when the switch
is in position “up” – then the lamp - 24
is not illuminated.
The amplifier is on when the switch is
in position “ON” – the switch is
illuminated in red. In this position the
amplifier does not play, but tubes are
hot, and you can change channels.
HINT: Before turning the amplifier on,
always make sure that the Standby
switch is in position “up” – it will
extend the life span of the tubes. The
amplifier should be turned on in the
following way: first, turn on the Power
switch and wait about 1 minute. Next,
you can turn the Standby on.
Turning off the amplifier works the
other way around. First, turn the
Standby on, then wait about 1 minute,
afterward you can turn the Power off.
