I had an Ibanez Tank flanger for decades and it did me well. I got it back in the 1990's and it finally died on me. I should have gotten this sooner. The momentary function works great for songs like Hear About it Later by Van Halen.

Sound
I like playing a lot of 70's 80's & 90's rock to softer metal. This pedal sounds incredible and cuts right through the mix and still can be as soft in the mix as you like. It does Van Halen music perfectly.

Features
It also has a couple added features that the BF-2 BOSS pedal that's discontinued doesn't. Like momentary function and the Ultra mode.

Ease of Use
Very cool and useful in ever position of this pedal unlike many other pedals that have a whole lot use useless sounds that are truly one-trick ponies. The BOSS BF-3 is not. Its very simple to dial in and learn this pedal in minutes.

Quality
This pedal like all BOSS are built like tanks and to last. The purple stand out on your board very well. There is a reason I use 5 different BOSS pedals on my board out of the 16 pedals I use at all times.

Value
Most BOSS pedals are priced very well.

Manufacturer Support
In 39 years of playing I have never had to contact BOSS for any pedals that has not worked and worked for decades. As long as you're not using a baseball bat to your pedals on stage, these things will… read more last for decades, from my experience.

The Wow Factor
It looks great, works great and just adds some extra things I can use to create music with. I'm not a follower of trends of what is in or what is out. I'm not 13 anymore and I like what I like no matter the era.
