Trained and practiced musicians will often recommend used guitar pedals or effects machines to enhance a new players abilities and sound. All musicians are interested in beefing up the sound they produce with their instrument, or changing it to add melody to their tunes.
A special effects machine or wah pedal, as some call it, will create a very different sound than someone normally hears from an instrument. With just the tap of a foot, these machines can make any strum sound completely different.
The machines can be used to either slightly or very dramatically change the sound that the instrument produces. It can create a feedback sound, sustain the note for a lengthy period of time, change the pitch or tone and filter out any certain pitches. They can make one chord sound like several. They can make some truly amazing sounds.
When you see a small metal box sitting on the floor in front of a player, you are seeing the most common type of device. This is the WAH-pedal, named because it simulates the sound that the player is trying to get. They will step on it to activate it and strum the instrument to produce a unique and different sound. It is connected to the instrument with a cable.
There are many of these that can be purchased used or new on the internet, from fellow musicians or in music stores everywhere. The foot pedal is the most common but you can also purchase a rackmount, which as several pedals to produce different sounds.
Used guitar pedals, rackmounts, effects machines and other musical accessories can also be found all over the internet, at flea markets, yard sales and in the paper. They are wonderful to have when a musician has gone past the point of one note melodies and needs to add something special and wonderful to their music.
