iamqman's review - Boss BF-3 Flanger

The Boss BF-3 is the newest edition to the Boss family flangers. Boss has built some great sounding flangers in the past and this one is simple the newest edition to the product lineup.

This pedal is very easy to use and you can get a great sound out of it very quickly and very easily. This is the jumbo jet flanger tone very similar to the Eddie Van Halne flanger tone he was able to achieve with the MXR pedal back in the late 70's early 80's.

This is one of those pedals that takes over your tone. It can be lightened up the nature of this unit is to give you a great heavy effected sound. So you probably want to use it sparingly as it is a powerful sound that comes from this pedal.

Any guitar and amp you use it with will sound good. It doesn't take a special piece of equipment to get this thing ti shine. I would prefer a modded Marshall and a superstrat of some kind and you'll be able to get that "Unchained" tone very easily.


At new these units come in at around $139, which isn't bad for a great sounding flanger unit. You can find these pedals just about anywhere you buy musical equipment. They are easy to come by and looking in the classifieds might score you one under 4100.

I would recommend this pedal to anyone needing a decent sounding flanger that will be road worthy and a good accompaniment to your pedal board and rig.
