Music gear is not only expensive to buy but also expensive to maintain. A full maintaince job can lead to the restoration of the gear. The first step in music gear repair lies in identifying the area of discrepancy. If you are not aware of the area you can land up in trouble by probably spoiling the gear.
Music gear is sensitive to even slight changes in the weather. It is always advisable to keep the gear in a protective environment. When not in use try to keep it wrapped inside a box with moisture absorbents. If the humidity or the moisture content in the air affects the gear, the sound quality may start distorting or sometimes even disturbing the entire signal flow.
Various gears are found faulty due to various reasons. Thus, it is necessary to know the reason for the fault. While repairing keep a note of the power related issue. Repairs and upgrades to the power supply and attention to power and ground distribution can reduce power-related noise without significantly altering desirable sonic characteristics.
For music gear like keyboards and synthesizers, the musician can face problems like low-output after sometime or power failure. But with an instrument like a guitar whether acoustic or electric repairing can really be a long task. However, the trick lies in identifying the area that needs repair.
If you are dealing with a guitar you can start with the guitar neck. That is because the guitar neck over time will warp because of the constant string tension. If your guitar has become harder to fret it may be a sign the neck needs adjustment. To check for warping remove the guitar strings from the bridge, not the tuning keys, this way you can put them back on without restringing. To be sure take a yardstick and lay it edgewise across the neck. It should lie evenly across the frets. If not, then the neck needs adjustment. To adjust your guitar neck you need to tighten the truss rod by turning the nut clockwise. However, do not over tighten it as you can break the neck. After all, we are trying to avoid costly repairs not create them.
Secondly, you will often hear a "buzz" in your guitar caused by loose frets. To check for loose frets press the ends of each fret with the tip of your finger to check for movement. To repair loose frets, first determine which end is loose. Place your guitar on its side and hold down the loose fret. Use one drop of super glue or similar product and let it run down between the fret and the fingerboard holding the fret down while it dries. Again, this is not a hard procedure but if you are careless you will cause more damage than what you had to begin with. Be very careful while performing this adjustment. If you raise the string height too much you may change the intonation of your gear. If the string is to low it will cause a fret buzz.

Sound Effects For Your Use In Music Production
To Produce or create a different range of sound effects for use with your music prodiction I will begin by explaining the different types of controls that are in most commonly used in filters and EQ effects
Cutoff frequency/Cutoff point:
The designated frequency of a filter after which the sound is not allowed to pass. In a high-pass filter, a high cutoff frequency will be excessively trebly and bright, as no low frequencies will be present. In a low-pass filter, a low cutoff frequency may be too muted and dark, as no high frequencies or overtones will be present
Attenuation
This will reduce or silence the desired frequency
Bandwidth/Q/Resonance/Emphasis/Peak
Bandwidth/Q/Resonance/Emphasis/Peak. The filter effects the range of frequencies on the desired side of the cutoff point and measured in Hertz, so it relates to frequency. Although if it was measured in octaves It would be more efficient
The usage of the terms 'bandwidth' and 'Q' are most commonly used to relate to recording purposes. 'Bandwidth' is the most useful, because it tells you about the overall sound control. Q is short for 'Quality' or, 'figure of Quality'
Resonance increases the frequencies around the cutoff point and is regularly used in synthesis. It is also used to put the filter into self-oscillation, which is not usually done with a recording.
To control the sound effect, you need to learn about the different EQ types. Here are the EQ types you will encounter.
The 5 different EQ types are:
Fixed EQ. This is usually a single control Like Bass or Treble. Mixers Could have Low (bass) and High (treble) EQ controls. The cutoff frequency here is fixed and you control the amount of cut or boost.
Graphic EQ. The frequency ranges are fixed divided into a series of bands to make cut and boost individually. Each row of sliders control a specific frequency band. They are common on hi fi systems. It also stands alone studio devices and can be found in software. Nevertheless, you can technically divide the spectrum into any number of bands, typical divisions on hardware units are 15 and 31 covering two-thirds and one-third of an octave ranges respectively.
Parametric EQ. With parametric EQ you change the frequency of the bands. It has typically three or four bands, each with three controls - cutoff frequency, bandwidth and level, allowing you to use specific frequencies within a very tight range.
Paragraphic EQ. This is a kind of super-parametic EQ. It blurs the line between graphic and parametric. It offers several bands like a graphic, but with user-definable frequency bands like a parametric; However, as this can become quite complex, they also tend to have highly-graphic interfaces to watch exactly what frequencies are being affected.
Sweeping/Semi-parametric EQ. This is the middle between a fixed EQ and a full parametric EQ - while the bandwidth is fixed, you can control the centre frequency (the cutoff point). It's common to many mixers. Normally, you can find fixed Low and High EQ with a sweepable mid range control.
