Guitar pedalboard
From Wikipedia, the free encyclopedia
A guitar pedalboard is a container for electric guitar effects pedals and their power supplies. The pedalboard comes in many different forms and shapes and many guitar players make their own. In general, it has a flat surface where pedals and their power supplies are attached using Velcro or some other adhesive substance. Fig. 1 shows a custom-made pedalboard with a power supply attached at the bottom.
Some pedalboards have the form of a suitcase. Some even come with wheels for easy transportation.
[edit] Guitar effects pedal power supply
Most effects pedals use a DC power, but with different voltages depending on the manufacturers. Possible voltages are 9v, 12v, 15v, 18v, 24v, and 40v. 9v is most common. Some effects pedals accept a range of input voltages and different voltages may produce somewhat different effects. A guitar player can experiment by varying the power supply voltage to generate the desired sound.
The DC power can be generated by battery, DC power supply, or a combination of rechargeable battery and its charger. Each has its own advantages and disadvantages.
Using individual battery for each pedal works fine for occasional players, who do not have to worry about the replacement battery cost and the changes in sound as batteries get tired. A battery typically lasts around two hours. Professional players normally replace all batteries with new ones before shows.
Using a DC power supply is a good alternative even though the initial cost is higher; however one has to pay attention to ground loops and power line hum. One can hear the annoying hissing sound by turning up the amplifier. The use of multiple power supplies would aggravate the problem. Hunting for ground loops is always tricky.
Noise gate helps to reduce noise level by suppressing the signal if it is below a threshold. This would control the unwanted noise, but does not remove the noise from the signal.
The third approach is to use one single powerful rechargeable battery to drive all the pedals and a battery charger to recharge the battery. This eliminates ground loops and the pedals are grounded at one single point -- the amplifier. There are products in the market that can power 20+ effects pedals for eight hours within one single charge. The effect pedals are connected to a rechargeable battery via isolated dc/dc converters, which can produce the required voltages.
Combining a rechargeable effects pedal battery with a “pedalboard suitcase” gives a worry-free and ease-to-use package for guitar players. It also reduces the setup time prior to a music show.
