The Boss BF-1 was the original flanger that led to a long line of descendants that continues today.
Years of Production: 1977 - 1980
The Boss BF1 is a flanger pedal designed for use with electric guitar, but will work with just about any type of electronic instrument.
The pedal simple has parameters for manual, depth, rate, and resonance all in the form of knobs. That is pretty much all there is to the pedal, so as you can see it is quite simple in make up. The sound quality of the Boss BF1 is incredible. Since it is a vintage pedal, it definitely has a vintage sound to it, meaning that it is warm and has an analog type of tone. It has a rich sound that is round overall, and is versatile as playing with the parameters will give you a variety of different tones. Go from a space age wobble to a very convincing Leslie emulation and everything in between.
No box, as is, works perfectly, has playwear, comes with a (non original) power supply.
