Boss BF-2 Flanger

At some point when the compact line of Boss pedals took off it was realized they needed to have a flanger. The original BF-1 had a much larger case and took up way too much real estate. The original BF2's sported black knobs but little has changed in the 20 years it has been around. When production moved to Taiwan they changed the knobs to white like this specimen. No other compact Boss effect has undergone as many lable changes too. Black, Green, Pink, Orange and Dark Gray were spotted on the backs. The Cure used this particular model on many albums. The unit is still available today.
