One of the biggest pieces of equipment that you can own when you become an acoustic guitarist is an acoustic guitar preamp; a device that can drastically change your sound for the better. However, if you are unsure as to what an acoustic guitar preamp actually does, or why you need one, you're in for some good luck. Acoustic guitars are usually fitted with a bridge which takes a pickup from the neck of the guitar and sends it to an amplifier which splits the signal to about six different speakers. This is what produces the music. The number of speakers can be varied depending on how much space is available. Sometimes the number of speakers is only two or three; sometimes it can be as many as nine or ten.
Playing live gigs is all about the tone of your instrument and how you play it - and acoustic guitar preamps help you to achieve that perfect tone before and during a gig. It helps you to create that desired tone that will make your audience sit up and take notice. So if you are playing a gig at your local pub during the late evenings, a good set of acoustic guitar preamps will be worth their weight in gold. Imagine being able to hit those high notes that everyone loves so much.
As with many musical instruments, an acoustic guitar preamp can also enhance your sound so that you can get even more guitar feedback. You may already know that amplifiers can take the tone of an acoustic guitar and give it some depth and warmth, but they often come at a cost. An amplifier is like a larger version of a compressor - it increases the volume of whatever you are playing and makes it louder. Acoustic guitar preamps work in a similar way - they amplify the sound and cut the volume back a little so that your audience can appreciate the full range of your sound.
In addition to enhancing the tone of your instrument, acoustic guitar preamps can help you to stay in tune when playing. When you are just starting out it can be easy to lose the knack for keeping time. Not only do you need to pay more attention to the actual sound of your instrument, but you have to keep your body in tune. All too often beginner guitarists try to hard, and when they do they find their self falling into the "zone" just before the guitar breaks down completely. This is because the brain's activity has increased so much that there is now nothing left to do but fall back into that zone again!
The best way to avoid this problem is to simply use a three-band equalizer or compressor with a foot pedal on your electric guitar. These are designed to give you the boost you need without hampering your lead duties. If you choose an amp with three channels and also a three-band eq, then you will be able to blend your sound with your other instruments, your audience, and the overall tone of your live performance.
The two knobs on the front of an acoustic guitar are usually labeled a "tone control," and a "gain knob." The tone control knob controls which tone your guitar will produce when you play it. The gain knob is used to change the level of the sound you are trying to achieve.
Many acoustic guitarists prefer to use a combination of both a compressor and an equalizer. When an electric guitarist plays electric guitar, he uses one diaphragm to generate the sound and another to control the amount of that sound. The di tone knob is used to match the level of gain to the desired level of sound.
In order to achieve the best acoustic guitar tone, you will want to find an amp that allows the player to experiment with different EQ settings. Some players like a more aggressive or less distorted sound. Others prefer a smoother tonal balance. By using a combination of both the di box and the eq, the right sound can be achieved.
