On this aspect of the guitar cable to amp, many people have different opinions, today I will give you some basic knowledge to popularize some guitar cable misconceptions
First, how to define a guitar cable. When it comes to guitar cables we have to talk about pickups first, there are many different types of pickups that work. In the use of musical instruments pickup is a kind of microphone, to be precise, is the paste type radio microphone. So from this perspective, the guitar cable as a carrier of the sound signal transmission, is a kind of audio signal cable, that is, with a shielded audio signal cable can be used as a guitar cable, and there are some video signal cable can also be used as a guitar cable. So, in fact, what type of guitar cable used, what structure of the line base is not important, the important thing is whether there is to give you the desired tone. Like I often say a joke, if I give my guitar to wear a shoelace to let the tone improve, I will use the shoelace.
Again, good shielding and low bottom noise are the basic requirements as guitar cables. If a guitar wire shielding is not good, as long as a plug inevitable bottom noise up, even if 10 3 meters, but also can not be used. So those with good wire shielding, low noise as a selling point propaganda itself is misleading.
On the other hand, the guitar as an unbalanced signal output instrument is not only a single-core coaxial signal cable as the cable base, on the contrary, high-end models of guitar cables around the world use a two-core balanced signal cable as the cable base. The main purpose is to connect the negative pole through a shield with one of the signal core, and the other end of the shield will be cut off and wrapped, only the front of the type of negative core connected to the negative pole of this end of the method, so that the shield in shielding the external signal interference generated by excess capacitance will not consume too much of its own signal transmission in the high frequency, so that the tone is more transparent, so that the welding method is called the single grounding method. Of course, the use of a single grounding method of guitar cable are directional, only in the direction of connecting the guitar house effects or speakers. Specifically, the unshielded end of the guitar, with a shielded end of the effects or speakers.
Also second, about the sound coloring. Many friends will be the sound coloring and signal loss into a conversation, which is inaccurate. Sound coloring mainly refers to the rendering of the frequency band and frequency band, the main parameters are reflected in the capacitive resistance value; and signal loss is commonly known as eating tone, which is mainly reflected in the impedance value. Then the tone dyes high and low at the same time have a positive and negative impact on the tone, so in the use of different equipment and effects module, in different tone building stages need different degrees of tone dyes. The correct view of tone dyes, the reasonable use of tone dyes will make our tone more expressive.
Finally, I'd like to address the issue of bottom noise. In our guitar tone system, the bottom noise is too large 95% of the reason has nothing to do with the connection line. The first big possibility of the bottom noise, is the power and signal line spacing is too small, because the power supply for the strong, signal line for the weak, the distance between the strong and weak power is too much will produce too much bottom noise. The second major reason, the wall plug ground wire is not connected, in this case, the bottom noise is especially large, so when you encounter such a problem, it is best to ask a professional electrician to reconnect the ground wire. The third major reason, the interference of external current on the power line. Especially the impact of wireless signal transmission equipment is the largest, so it is recommended that the use of professional 3 or more than 3 filtered power supply, can effectively reduce external interference generated by the bottom noise too much. The fourth major reason, effects, box head parameters are not set properly. I've seen many friends play distorted tones, distortion look great, while the compression is also open, plus the instrument itself tone also screwed to the head. Not to mention that the tone is not paste, on the above parameters set, the bottom noise can not be small. So find out exactly where the cause of the excessive noise is, you can effectively solve the problem and avoid the waste caused by changing the line when the bottom noise is large, after all, the line is innocent. Also want to remind, as long as the tube speaker, as long as the overload and distortion, there will definitely be bottom noise, bottom noise itself is part of the composition of the guitar tone. What we need to do is to improve the signal-to-noise ratio, not to eliminate the bottom noise, because eliminating the bottom noise is to eliminate your tone.
To sum up, building the right perception of the wire, all based on the objective facts that we can hear. It will allow us to gradually have better control over the construction of the tone, and the tendency of the tone. I hope the above content can provide some help for hobby guitar friends, personal opinion, for reference only.
