Guitar Amplifiers Tips

No comments

Guitar amplifiers fall into two categories. First, the combination (combo) amplifier is a single unit containing both the amplifier head and audio speakers. The amplifier head, commonly referred to as the ‘amp head’ houses electronic circuitry for the preamp, installed effects processing and power amplifier.

The second category of guitar amplifier is called an amplifier stack or ‘amp stack’, for short. The amplifier head is a separate unit and connects to the audio speakers via a series of cables. The amplifier head is conveniently placed on top of the audio speaker cabinet.

In regards to engineering designs, there are a range of options.

Solid State. These types of guitar amplifier were engineered to improve on their predecessor, the vacuum tube amplifier. Solid stage guitar amplifiers are considered superior to the original tube amplifier design, as least in engineering and technical terms. However, many do not agree. Solid state guitar amplifiers use higher frequencies compared to tube amplifiers, deliver more audio range and produce more power and wattage. Solid state amplifiers are generally easier to repair, lighter, less expensive.

Vacuum Tube Amplifiers, On The Other Hand, Are Considered By Many Musicians To Be The Superior Choice Simply Because Of The Perceived Analogue Audio Quality Guide. A sound reproduction that is termed rich and full. This analogue and human bias prevails among purist musicians despite tube amplifier limitations such as: lack of power, fragile and prone to tube failure, comparatively heavy and higher repair and servicing costs.

Hybrid Amplifiers are an attempt by some designers to capture and blend the qualities of both solid state and vacuum tube amplifiers.

Modeling amplifiers started to appear in the market in the late 1990s and incorporate microprocessors, digital signal processing and software. The objective of this engineering direction is to simulate the sound qualities of the analogue tube amplifier.

Bass Amps

With the help of the bass amp, a bass player is able to create much better sound and tonal clarity. The market is awash with many types of bass amps, out of which you need to pick the one suited for you as it is only with the bass amp that you can add punch to your guitar. Having the right Head and Cabinet setup is very essential to ensure the production of rich sound.

Good sound quality is possible only through the appropriate size of the bass speakers.
Just as the amplifier is important to the bass player, the speakers are equally important to the set up of the bass cabinet to yield suitable clarity in acoustics. You should choose the speaker dimensions depending upon the playing manner of the bass player and should not be under the impression that only speakers of higher magnitude can deliver crystal clear sound.

In fact, the smaller sized speakers perform quite well in dense situations. Speakers in the range of 12 inches to 15 inches dimensions have been known to produce consistent output and they are also quite versatile.

A richer musical experience can be obtained through the mid range size speakers, rather than the small 8 inch ones, as the tone comes across as too flat. It is a fallacy to think that speakers of higher magnitude like the 18 inch ones can provide you with a wholesome musical result, as very often they lack the clarity and punch that the mid range size speakers are able to provide. Utilizing a blend of speakers with diverse dimensions produces music which is more gratifying, as they are able to cater to the entire scope of frequencies.

By packing together varied sized speakers, each covering a set of frequencies, you are able to produce sound that is complete and pleasant to the ears. Since the enclosure is very important in the way it is designed, it needs to be adequately big to enable free airflow.

Protect the speaker cones.
Metal grids are normally used within the bass cabinets in order to screen the diaphragms of the cones of the speakers from any wear and tear due to extended usage. Besides the metal grid, the closed space holding the speakers must be equipped with metal borders and caps so that the enclosure is not split due to extended usage over time.
