The joy of using this pedal is just how small it is. No matter how large your pedalboard is you will always be short on space as your pedal collection grows. That is why pedals like this are so important as you can fit them in to any small space on your pedalboard. No longer do you have to take up most of the space on your pedalboard for a sound you may only use for one song. Because of the size of this pedal it requires a DC 9v power supply and can not work on standard 9v batteries.
