ntroduction to the guitar sound on some of the basics in order to make everyone able to quickly grasp the practical use of this knowledge, we assume that you are now just beginning to use a guitar amp for beginners, never touched the face of this equipment, how should you do to bring up the satisfying sound of it?

The first step: Use with shielding the signal line (microphone cable) to connect the guitar output and input of the speaker, if you are using a wire inferior quality or too thin shielding layer is susceptible to external electromagnetic signal interference. Individual practice-type guitar amp generally only has one input channel (1ch), a little better this channel will be divided into high-gain and low-gain two interfaces. Generally, the cable plugged into an outlet on a high gain it. There are two more channels for speakers, you can plug in a guitar signal line on the channel you have the desired effect, such as if you want to make the speaker produces a reverb effect, put the plug in the Reverb signal line interface .

Step two: Turn the power switch on the speaker. Although this is the general electrical knowledge, but the guitar sound and ordinary household appliances is not exactly the same, especially when you use the speaker is when a tube amp, turn on the power switch, the tube to go through a "warm-up" process in order to work, which is decided by the tube works, and if the power is turned on immediately after playing a number of multi-pipe will advance aging. Press down the power switch for 10 seconds later, and then open the ST-BY switch can work normally. If you are using transistors or integrated circuits for digital guitar amp, you do not need to warm-up, so there is no ST-BY general this switch up.

Step 3: If you use this speaker is never touched before, you need to first determine what this speaker sound characteristics. You need to adjust the tone (EQ) for each knob (generally 3: HIGH, MID, LOW, respectively, to control high-frequency, intermediate frequency, low frequency) transferred to the "5" position (middle). If you are the speaker tone circuit with gain (not a simple attenuation circuit), then you should put each knob is screwed into the 12 o'clock position, neither of the circuit amplifies the signal of each band, nor decay.

Step Four: The majority of guitar amp has two or more of the level gain control knobs, even the most expensive personal practice model is no exception. Both knobs are called Gain and Volume, also called a Volume and MasterVolume's. As the name suggests, Gain control is mainly used to put a lot of initial input signal, which produce a special class of first-class tone distortion circuits; while Volume is used to control the release of the final volume of the speaker size. You can adjust the Gain very large to get enough distortion, while Volume may not need much, the key depends on the site of PA situation. In this step adjustments, you still need to Gain transferred to the "5" position, while Volume is watching how did you hear the volume. If you feel the distortion is not enough, you can slowly increase the big Gain tune, but this time the sound emitted by the speaker will also increase sharply (because the total amplification becomes large), so it is necessary to Volume little knob. In short, the purpose of this step is to adjust production to sell their satisfaction with the speaker distortion (distortion sound with the use of effects obtained with distinction), but also must pay attention to the balance between the final volume and distortion.

Step Five: After the completion of the previous step speaker distortion commissioning work, we come back to the use of the tone circuit distortion sounds fine-school low-frequency correction. Most of the speakers have a high frequency (HIGH), low frequency (MID) and low (LOW) to adjust the tone of these three bands perform a function. Tone processing is a very complicated and trivial, many recording engineers often need to take several years to tuning method for comparing various instruments through touch, guitar speaker adjustment, although not so troublesome, but it is also very expensive time. Therefore, in order to make your ears satisfied and we certainly do not begrudge the time and keep trying, sometimes you obviously adjust the high frequency (HIGH), and changes in the sense of hearing, but in the low-frequency (MID). Some models are also equipped with a guitar amp Presence regulation UHF part (existence) knob, and make clearer high frequency "BrightSwitch" switch. However, if you abuse the two controllers, will be very easy to make sound become "lean", but also may bring annoying noise. So, when generally only rely on HIGH, MID and LOW three controllers can not recall a satisfactory tone as a "last resort" to use. Step Six: After above this some "frustrating", in order to make a sound with a certain sense of space, we can adjust the reverb sound controller (Reverb). In general, the more advanced guitar amp, the additional parameters of the more abundant variety of adjustments, but the greater difficulty adjusting. For example, like RolandVGA-7 as a high-tech guitar amp, or even to simulate a variety of models and different pickups guitar sounds through an internal digital circuits computing (DSP). If you sound now emanating from the speakers still not satisfied, you can return to the third step earlier, according to several points we noted it again. Sometimes, however, limited to the time and quality of the speakers you have, you should do some appropriate compromise, after all, a few hundred dollars of speakers and sound you hear on the album million speakers emitted certainly can not ratio.
