Overview: The popularity of finger playing in recent years has made many guitar lovers obsessed with her. When we look at the performance of some masters, we will find that they use electric box piano. In fact, the use of electric box piano is very wide. When you participate in a performance, the sound of the acoustic guitar is very small, and when the audience is large, most people will not hear you play. And the electric box piano can solve this problem. And the electric box piano can also be connected to the effect device to produce a variety of timbre effects. Today, I will talk with you about the process of modifying the box violin. First, prepare some materials and tools: paper, pens, rulers, scotch tape, sandpaper, screwdrivers, steel files, drills, electric drills, and soldering irons. The most important thing, of course, is the piano and the necessary pickups.
First of all, we should reasonably design where to install the pickup on the piano. The body itself is a shape that approximates the Arabic number "8", so you can consider installing the pickup in the first or second body side panel where there is a curve. After the selected place, use a ruler to measure the size around the pickup, be sure not to measure the area above, otherwise it will not be installed on the screw can not be installed, and then use the ruler to compare the suitable position on the piano. Then draw the flat surface of the pickup with paper and pen. Here, we must remind the beginners and students who have just touched the piano for a short time, and the plan drawn on the paper must be completely accurate, otherwise it will cause a series of chain dangers to "scrap" the piano, which is not what we want to see. Has the plane been drawn? Okay, so place the plan in the exact position you just compared it with the ruler on the piano, and secure it with scotch tape. It is also a particularly important place to go here, and we must remember not to be afraid of wasting tape and making the figure very lax on the piano, so that the position will be inaccurate when punching the hole.
Everything that needs to be done, everything that needs to be prepared, it's time to get started. Take out the "heavy weapons" and load them. When you choose a drill bit, it is best to choose a fine drill with a smaller diameter value. In this way, the drilling time can be more accurate, and the burr after the drilling will be much less. After installing the electric drill, begin to punch the hole. Note that it is best to punch holes in the line of the plan, otherwise the hole will be larger than the area of the pickup. After making the holes, use the prepared steel file to smooth out the uneven burrs in the hole ring. In this way, the first punching task was successfully completed. The first one? Why do you say the first punch is done? Yes, it is necessary to drill holes in three places of the body, and the one that has just been punched is the largest, and then two small holes must be punched. One is at the bottom of the body, while the other is in the horse bridge groove of the body.
Entering the next part, before we start, it is necessary to talk about the types of pickup with you. The electric box piano pickup on the market now is really a variety of formats all have, most can be divided into two categories. One type is ordinary pickup; The second type is multi-function pickup. Most of the multi-function pickups add tuning function. There are two kinds of pickups with tuning function that use leds, and there are two kinds that use LCD screens. In the design of the pickup with tuning function, the battery is mostly not placed in the balance adjustment, but is together with the guitar connection port. Guitar connection port, there are two kinds of single interface and double interface, in order to facilitate the connection of more audio equipment and piano. Therefore, the punch task at the bottom of the lower end of the body will be punched in different places due to the different types of pickup, and the size of the hole is not the same. In this article, the ordinary pickup is used in the operation demonstration, and the modification process will be slightly simpler than the multi-function pickup. Remove the strap buckle at the bottom of the piano body with a screwdriver, and enlarge the hole from the original hole. Before the final punching operation, all the strings on the instrument must be removed and the bridge removed. Punch holes in the slots. When drilling, pay attention to the size of the drill, and the good mouth should be just right in the groove. The holes are all punched, and the next step is to install, and there are not too many precautions in the installation. Just screw the parts that need to be installed here and there. The only thing to say is to connect the wires at three places of the pickup before fixing the screws. When using a soldering iron, if the conditions are limited and there is no constant temperature of the iron, pay attention to the change in the temperature of the iron, so as not to waste too many connected wires. It's done! Is it really done? There is a little bit of finishing that I hope we can all pay attention to. After the pickup is installed, there will be a lot of wires in the body of the piano, if the good treatment will affect the sound quality of the performance, we can use transparent tape to stick the wires in the interior of the piano body to fix it, in order to prevent the fall off after a long time, it is best to stick several places. After the sound bar is placed in the Maqiao slot, if the bridge has been installed, the position of the bridge must be higher than that of the piano before the modification, and the string distance between the strings and the fingerboard will be much higher than the original, which affects the feel of the playing. So be sure to sand the bridge to the size required by the instrument without changing the string distance between the front string and the fingerboard, which is very, very important! In this way, this electric box piano is done. In order to facilitate everyone to understand the operation process, so use a lot of space. Take your time and think. In order to ensure the safety of the operation, if you have the conditions, you can first try with a dead piano. Speaking of this, is everyone a little moved? Do you want to modify your own Aegean? So, the heart is not as good as action, we start to do it, what is the more simple and convenient tips in the operation? More communication between piano friends. Experience is the most valuable asset.
