Boss BF-3 Flanger Pedal

I got my first Boss Flanger in the 1970's and just got the BF-3 for updated versatility. The Flanger adds elements of creative sound that is adjustable to the song tempo. Also, I don't know why people buy the so called "boutique" pedals (Flangers) when Boss has the years of reliability and quality. Furthermore, I find it easier to activate a Boss pedal on a pedalboard as opposed to a small single button switch pedal which is how most other pedals are designed.

All You'd Need in a Flanger

I can't say anything bad about this pedal. I don't use a ton of flange, but when I do, it has everything I need. Has a great, natural sound and a TON of settings/features. More than I need, to be honest. But I like having options. Great pedal.

Great Flanger

Great flanger sounds! Very tweak-able settings, with an organic sounding sweep. The "momentary" function is nice - you can hold your foot on the switch for as long as you want flanger. When you take your foot off, the effect shuts itself need to stomp once for on, then again for off. This is great when you only need the effect for a few seconds in a song (which is pretty common when using a flanger). I play a lot of Tool songs and Adam Jones uses LOTS of flanger. The BF-3 gets me the perfect sweeping flanger sound for songs like Forty-Six & 2 or Pushit. This pedal is much more flexible than my previous flanger (MXR Micro flanger). The only reason I'm not giving it 5 stars is because, like most Boss pedals, it really eats up batteries quickly. I usually use a One-Spot so it doesn't affect me, but people who use batteries in their pedals won't like that. But all in all I like it a will be the last flanger I'll ever need.
