The Master Classic amp is based on a MTD Master Tube Design technology.
It is our own groundbreaking technology which permits us to create powerful guitar amplifiers in
very compact shapes. This technology uses all the significant features of tubes which determine
the warm, classic sound of guitar amps. We offer players an amplifier with extremely light weight,
very compact dimensions and powerful sound. The sound characteristics and power of the
amplifiers based on our MTD technology are equal to the classic tube amps with the same power
rating.
The guitarist has for his disposal two channels with separate GAIN and VOLUME adjustment. It
makes possible to use two different sound settings which are controlled by foot-switch. The
amplifier is equipped with a classic equalizer containing BASS, MIDDLE, TREBLE and
PRESENCE potentiometers, as well as sound changing switches BOOST, BASS-RANGE and
MID-RANGE. Those options allow for additional experimentation with the sound. In case of the
Master Classic four power options can be choose: 90W and 40W in STAGE mode and 20W and
12W in STUDIO mode. The Master Classic is designed to work with speakers of 4-8 and 16 ohm
impedance.

Signal with speaker simulation Signal with speaker simulation
Line output provides two signals: with and without speaker simulation.
You can use speaker simulation (with mono plug)
or both of them (with stereo plug).
Amplifier produces high volume levels. Staying in places of high volume levels could
cause permanent hearing loss.
Do not use the amplifier in humid and dusty places.
Do not operate the amplifier through the unearthed socket.
Do not leave the amplifier in the vicinity of children.
Do not use the amplifier with broken power outlet or improper power cord.
Do not install nor use the amplifier near any heat sources, in case of overheating the
amplifier turns off
In order to ensure proper air circulation, do not block any of the ventilation openings.
Never put any liquid containers near the amplifier.
In case of any objects or liquid access inside the amplifier, urgently switch the apparatus
off and unplug the power supply cord.
Protect the amplifier from any strikes.
ATTENTION: To reduce the risk of electrical shock, do not remove the back cover of the
amplifier. Inside parts can be repaired only by qualified service personnel.
WARNING: To prevent the risk of electrical shock do not expose this appliance to
moisture, rain or any liquid.
Do not cover the vent
holes!
