If you know a bit about flange history, you know the BF-2 ROCKED. And it doesn"t take a quick fellow to take a look and realize that the BF-3 you"re looking at right now has a little to do with the BF-2. In fact, it has a LOT to do with the BF-2. This successor gets you HUGE stereo flanging sound... massively thick, awesomely tasty. And for an extra-delicious sound, BOSS enhanced the BF-3 giving it two special new modes: Ultra and Gate/Pan. To take charge of your BF-3 and bring it into service, you can use a momentary flange mode. Or, you can rock out with the tap tempo and go on and do your thing. When you want flange, you want the BOSS BF-3. Rules.
