The construction of an electric guitar involves a lot of materials which affect all the characteristics of the guitar. Every part of an electric guitar influences the stability and performance, in relation to price, versatility or styles. I do not intend to go into technicalities, the idea is that we can all understand what the issue is, which electric guitar is the most suitable one for what we want to play.
The first thing is to think that for a difference of 50 or 60 dollars, we can have a poorly constructed guitar, which can have unsolvable problems and prevent us from playing well. Sometimes for those 50 dollars, you could go from having a good one or a ‘toy’ guitar from a beginner pack to having a guitar from reliable brands like Yamaha.
For example a bridge of low quality, if it is Floyd Rose, it can become impossible to touch without constantly losing the tuning. This happens a lot in electric guitars that reach up to 800 dollars for example. The bridges can lose tuning with a simple bending. And changing the bridge of a low-end guitar is not worth it, so it is better to choose well.
If your budget is less than 600-700 dollars, you better go for an electric guitar with the fixed bridge to save you possible headaches. A soft brand, or an electric guitar of 300 dollars usually saves from one place or another. If you have Floyd Rose, which tends to make your guitar expensive, and ‘decent’ pads, be sure that the wood will be bad along with a few other things.
The famous and reliable brands usually have sufficient quality controls to make the neck poorly adjusted, and can be adjusted at home. Do not expect wonders, the mid and low ranges usually do not bring good factory settings.
If the guitar is low range, it is always advisable to change electronics, potentiometers, etc. And, if it does not come shrouded, and the electric guitar generates a lot of noise despite having quality, it is advisable to do so. A shield can be made at home, or any handyman who dares with it can do it.
The wood is really important. You will not find wood of the highest quality for 200 or 300 dollars, but if you are looking for a guitar with Floyd Rose, You can be sure that the wood will be really bad, and the neck will generate constant problems and, for many changes you make, your instrument will remain low-end.
In case you have bad wood, do not plan to make a change in the future. Your electric guitar will continue to be a low level, precisely because of those extra caprices that make it more expensive. However, an instrument with good woods, although a priori is low or medium-low, can become a good guitar with a shield and new electronics. If the wood is really remarkable, an original Floyd Rose bridge can be a good option.
