The feedback loop pedal provides dual functionality. Without the toggle switch activated it functions as a normal true bypass loop pedal, utilizing a special switch that allows you to isolate and bypass effects pedals that are not true bypass in order to preserve the guitar's original tone, or switch on/off groups of pedals at once. With the toggle switch activated things can get crazy. The feedback function of the looper is designed to send the output signal back to the loop's input through a potentiometer. This can produce some some very interesting results, ranging from oscillating, growling, chirping sounds, to flat out noise, to nothing. The key to the feedback looper is experimentation. Some pedals can produce great results while some have little to no effect at all. You can also try various combinations of pedals. I've had good luck combining fuzz and phase pedals in the loop. Your pickups and pickup selector position as well as your volume and tone controls also have a tremendous effect on the sound produced. The pedal's control knob determines the amount of feedback being sent back to the input. Sometimes you may need to turn it all the way up while other times you may find a sweet spot with the level turned low. Check out a few online videos for potential application of a feedback loop pedal. If making a lot of complex noise is something you're into, then look no further. The feedback pedal provides a strange sonic landscape and you never know what you're going to get.
This bypass loop pedal was hand crafted with quality components including Neutrik jacks, a rugged Hammond-type die cast aluminum case with a cool hypnotic graphic, and a semigloss clear coat finish. This pedal features an LED that can be run on either a 9V adapter (with a standard 2.1mm 'Boss' type plug) or a 9V battery (clip inside). The battery/adapter is only to power the LED; the bypass switch itself and the feedback control are totally passive and do not require an AC adaptor or battery to function. At 4.5"x2.5"x1.25", this bypass looper is also very compact. Similar pedals can retail around $150; get yours for a fraction of the price!
