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.

A very versatile digital flanger pedal

This is simply the best digital flanger I've used. Very versatile. You can change modes to create different effects. Simply a good choice.
