  • Stomp-Heads
  • Bass Heads
  • Pedal Effects
  • Speaker Cabinets

AUX input: used to pair stomp-head with other devices that can send audio signal.

BASS: one of the tones from 4-point equalizer, that are at the end of human hearing range (low frequency).

BOOST: The BOOST function performs two features at the same time: it boosts a signal at the input of the preamp, giving extra compression and raising the volume. Desired volume level may be adjusted by tweaking the potentiometer. By then pressing the BOOST switch located on the top of the amp, two different volume levels previously set will be obtained. The BOOST MODE is quite beneficial as it heightens the guitar solo during a live performances.

Channel: a representation of audio signal communication in a storage device or mixing console, used as sound reinforcement.



Footswitch: switches used to activate features like BOOST or MUTE by just simply stepping on it.

GAIN: input volume controlled by potentiometer. This will affect the overall volume from device, and can cause distortion in tone.

Head: heads are just amplifiers without speakers. Stomp-heads are floor standing version of heads, controlled mostly by stepping on footswitches. It can work as well as preamp without connecting to speaker.


Impedance auto detection: device can automatically adjust to a speakers impedance.

line output: allows the connection of the amplifier to a mixer or an external power amp. LINE OUT signal simulates the sound of the 4x12 CELESTION Vintage 30 cabinet.

MASTER CHANNEL: output channel.

MIDDLE: one of the tones from 4-point equalizer, that are at the middle of human hearing range (middle frequency).

MID-RANGE switch: The MID-RANGE switch changes the range of frequency of the MIDDLE potentiometer. This option is very useful in the proper setting of the guitar’s sound in an overall band mix depending on the style of music played and type of guitar used.

MIX mode: channels are mixed and used simultaneously. The MIX-MODE option has been designed for musicians who love to experiment with sound which is the result of blending several channels simultaneously. In this mode, all controllers in every channel are operational and allow the player to freely mix signals from all channels simultaneously to obtain a desired texture of sound.

MTD (Master Tube Design): It is our own groundbreaking technology which allowed us to create powerfull guitar amplifiers in very compact shape. This technology uses all the significant features of tubes which determine the classic sound of guitar amps. We offer players a fully analog amplifier with extremely light weight, very compact dimensions and powerful sound. The sound characteristics and power of our MASTER TUBE based amplifiers are equal to the classic tube amps with the same power rating.

Power Output Selector: allows to set in STAGE MODE / STUDIO MODE.

PRESENCE: one of the tones from 4-point equalizer.

Serial effect loop: it has two connections, SEND and RETURN. The signal from amp is travelling from SEND, through f.e. effect pedals, and then back to RETURN and to the output of amp. You can stack effects by this method.

STAGE MODE: one of the options from power selector switch. STAGE MODE stands for more power (60W or 25W).

STUDIO MODE: one of the options from power selector switch. STUDIO MODE stands for less power (15W or 7W).

TREBLE: one of the tones from 4-point equalizer, that are at the highest end of human hearing range (high frequency).

BASS: one of the MLO equalizer tones - low frequency sound.

CHARACTER: a knob which changes balance of Solid State and Tube Pre-amp.

CLIP: power amp indicator.

DBS: system designed to increase low bottom while preserving very clear and dynamic sound, this also protects speakers against fluttering when very low frequencies are applied. DBS provides the natural sound of the instrument even in the lowest registers.

EFFECT LOOP: used to add some external effects (e.g. effect pedals) to audio output patch, so the wave will be enhanced.

EQUALIZER: this device operate on audio filters by strengthening (boost) or weakening (cut) the energy of specific frequency bands or "frequency ranges".

GAIN: input volume controlled by potentiometer. This will affect the overall volume from device, and can cause distortion in tone.

MIDDLE: one of the MLO equalizer tones - low frequency sound.

MLO EQ (Mid-level optimization equalizer): The "MLO" (Mid Level Optimization) is Taurus proprietary system allowing for an easy, intuitive and extremely comfortable optimization of the overall sound of the bass guitar.

The MLO system provides all new possibilities. It ensures most accurate proportion of medium frequencies in accordance of your manual settings of bass and trebles. This very intuitive and logical system supports musician's choice for most desirable sound.

In addition, the MLO equalizer ensures virtually no change in overall volume while changing the bass frequencies. Unlike most of the standard amps, adjusting bass frequency the musician notices change of the sound not the volume.

MUTE: simple button that turns off the sound until it's pressed.

PUNCH: increases sonic expression.

RMS (root mean square): RMS is equal to the value of the direct current that would produce the same average power dissipation in a resistive load

SMPS: an electronic circuit that converts power using switching devices that are turned on and off at high frequencies, and storage components such as inductors or capacitors to supply power when the switching device is in its non-conduction state.

Switching power supplies have high efficiency and are widely used in a variety of electronic equipment, including computers and other sensitive equipment requiring stable and efficient power supply.

TREBLE: one of the MLO equalizer tones - high frequency sound.

True V: This particular feature allows for sending your instriment's sound directly to the mixing board through the LINE-POST-EQ output. The sound sent to the mixing board has exact the same parameters as the sound you can hear through your speakers.

TUBE DRIVE: by using two potentiometers CHARACTER and GAIN, You will conjure sound which can be produced only by real tube amplifier: Warm murmur, tube compression, as well as VINTAGE DRIVE.

The CHARACTER knob is a balance of Solid State and Tube pre-amp. The GAIN is used to achieve compression and overdrive of the amp's tube section, which is identical to the real classic tube amplifiers.

Combo: Hybrid of bass amplifier and speaker cabinet combined in one.

Freq response: is the quantitative measure of the output spectrum of a system or device in response to a stimulus, and is used to characterize the dynamics of the system.

Hc: All "Hc" Series cabinets are covered with hybrid polyurethane coating. The coating is extremely resistant to any kind of mechanical damage which may occur during transportation as well as protects the cabinets against moisture. It is also very easy to clean . An additional advantage of the coating with the polyurethane elastomer is a sealing and reinforcement of the entire cabinet's structure, thus eliminating undesirable vibrations as well as increases the overall cabinet's lifespan.

Impedance: speaker impedance is the “resistance” a speaker offers to the current supplied by an amplifier. This impedance changes as the sound goes up and down in pitch (or frequency).

Mono: means that sound is emanating from one source, like for example playing on only one loudspeaker, when there's only one wave of sound created.

Sensitivity: easily defined as the speakers ability to effectively convert power into sound, and it's measured in decibels [dB]. The higher the sensitivity rating of a speaker, the louder it will play with a certain amount of wattage.

Stereo: means that sound is emanating from two or more sources. By connecting more than one speaker, sound is reproduced in two separated audio channels, giving sense of the direction of sound sources.

Tweeter switch:
