Boss BF-3 Flanger Review (firsthand review) - Guitar Chalk

guitarchalk.com

The Boss BF-3 Flanger pedal is a versatile modulation marvel that excels in delivering rich, nuanced tones. With multiple modes and four EQ controls, it handles everything from subtle to intense flanging with aplomb. While the retail price is somewhat steep, savvy buyers can find excellent value in used options. The lack of a mix knob is a minor drawback, but the pedal's overall performance and adaptability make it a standout in its category. Ideal for those seeking a reliable, high-quality flanger, the BF-3 is a top choice for both beginners and seasoned players.

Very Versatile

It's great to be able to use it as a tremolo with a hint of flanger.. lately I put it after the distortions because the tremolo effect sounds better there, although it's easier for me to get the flanger sound I'm looking for by putting it before the distortions.. Using the bass input with the guitar achieves a less bright and artificial flanger sound..

It doesn't get better than this!

This pedal have been on most pedalboards out there... I grew up seeing lots of players, both guitarists and bassists, using this pedal. It sounds amazing, and compared to the BF-2 (which I have owned before) it gives you more options to fine tune your effect. I love the "Momentary" function, specially to emphasize some phrases during solos.

Versatile and tough

Definitely one of the more versatile Flangers available. The stereo option is pretty cool. It’s built well and has convenient boss pedal features, like easy battery door access. Overall really fun pedal to have.

great flanger

It was my first guitar pedal. Same as with the Green Russian, not used on the Adventures of Bail Seaweed tracks, but on everything else with flanger I use it.

This Flanger is mainly used when I don't want to use chorus or reverb but still want an airy sound

Great!

Does everything I want it to, is easy to use, never breaks or craps out! The tap function on this one works really well, I can use it mid song without any major difficulties. Nice to have the stereo option too.
