Hatsubai's review"Upgraded flanger"

Boss BF-3 Flanger
The BF-2 was a great flanger, but like all great things, they must come to an end. Boss decided to release another flanger with a few more bells and whistles. This is the new version that they introduced. It's basically an evolved version of the BF-2. You have a res, manual, depth and rate knob. Then you have these different modes to choose from. On top of that, you can choose between the bass input or guitar input for some different tones.


They really packed a ton in this pedal, and it's surprising how easy it is to use. It's somewhat of a pain trying to manipulate the small outer knob on the res/manual knob, but you get used to it. The modes feature on this is very handy, and I like how much they threw in this pedal. The manual is very clear as to what everything does, and they even give you a few example settings to try out. If you've never used a flanger before, it might help reading the manual. These pedals are built like tanks so no need to worry about this thing breaking any time soon.


The pedal is a little more metallic sounding than the BF-2, in my opinion. It also doesn't seem to be able to do the old school LeTekro trick where you could use it almost as a midrange booster. However, it's still a very solid flanger. You can get all kinds of different flanger settings with this thing thanks to the mode selection switch. Before, you were limited as to the actual types of flanging you could have. I never really cared for plugging the guitar into the bass input, but you might like it. The rest of it is pretty much like any other Boss flanger in that it's fairly solid, but not exactly the best out there.


The BF-3 is a pretty solid pedal if you're looking for a various range of flanges inside one small Boss enclosure. It's not the best sounding flanger they've ever made, but it's still easily capable of staying on my pedalboard if need be. I prefer the BF-2, but I would definitely not be opposed to having a BF-3.

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.

Boss BF-3 Flanger
The Boss BF-3 is a flanger effect stomp box. It has 1/4 inputs and outputs and is not a rackable unit. I believe it is an analog pedal, but I'm not 100% sure about this. It is a cool looking color and is much more versatile than its predecessor, the BF-2.


The configuration of the BF-3 is very easy to figure out. It has four knobs and one of the knobs has another knob on top of it. The first knob controls the resonator, the next controls the depth, the third controls the rate and the last knob is used to set what mode of flanger you would like to use. It is designed to get a wide variety of flanger sounds and it does just that. I've never used the manual as the pedal is pretty easy to figure out.


The sound quality of this flanger is very realistic sounding. It is easy to use it subtly and to hint with the flanger, and easy to go nuts to get some real spacey sounds. I have only used the BF-3 with guitar - a Gibson SG and a '76 Fender Twin Reverb amp. The flange sound on this pedal is top notch and totally professional sounding.


I first used the BF-3 about three or four years ago. I also have a BF-2, which is the Boss flanger made before this pedal and while the BF-3 is a lot more expensive it is definitley more versatile and overall has a better sound to it. While some sounds between the BF-2 and the BF-3 are comparable, the BF-3 has a more varied arsenal of sounds than the BF-2. While the BF-3 is a bit pricey you are getting a very well made pedal from a company with a great reputation. Overall this is great sounding flanger pedal with a ton of versatility.

Boss BF-3 Flanger
flanger is a cheap boss.
it's digital (versus BM-2, which is analog).
connectivity: a guitar input, low input, and a mono output for the stereo.
the pedal has 4 knobs, giving a double, including a notched offer 4 modes, so a lot of possibilities in sound.
convenient size (compared to my big muff 3X bigger!)

10/10 very good dear boss;)


I use it on my bass.
the manual is in English but is quite comprehensive and offers factory settings.
I use it in the end just loop my Advent chorus (CE-5 gift I leave a review minutes ago).

10/10 SAR's all good;)


well then, wow! the effect is really great!
the possibilities of sound sounds very broad, and we feel the difference between the 4 different modes that ofrent possibilities:

-Normal: A normal flanger, very pretty.
Ultra-mode: flanger longer present, a bit intrusive but totally usable.
-Mode gate / pan: this closer to a tremolo, very pretty.
Momentary-mode: normal flanger works is that it remains apuilé pedal, very convenient.

tap tempo is also very practical and can synchronize the effect with the song.
in short, a very good pedal that has spawned boss;)

with a distortion / fuzz like big muff, it sounds really great!

EDIT 20/03/2010: mode gate / pan, tap tempo pedal is saturated! I does not take away points because I hardly use this mode but must be reported.

10/10 is really good.


I have been using 2h intensive and I am very happy.
I have nothing ésailler Advent to buy it.
I paused on the pedal, really everything.
the quality / price is EXCELLENT in my opinion. really happy with my purchase.
I like: sound, size, but made ^ ^
flanger versatile and beautiful. for 109 euros, it's really perfect!
Yes, I will ever really no choice problem is a really good flanger to me (maybe not organic assai, but ...)
one caveat: the pedal is ULTRA greedy! it's been barely a week since I have stacks and its already almost dead! therefore a good power supply is required!

7 / 10 a near flawless, very good pedal. hallucinate but the consolidated stack! (Yes I did unplug the jack;) ) therefore only 7

Boss BF-3 Flanger
Digital Flanger, Boss format, 3mode, 4potard, guitar input and low input, stereo output


Ben is a bit more complicated than the ehx but the manual is much more provided it comes out easily sound simply amazing


Numerical not very hot, but extremely clean and clear sounds are quite aggressive and powerful, customizable and how to say it's a pedal effect that makes the effect .... if you want to make the effect leaves to exaggerate go for it !!!!!


I've had this morning I had to try a package before (MXR, EHX, multi-effects such ToneLab, korg, zoom, even as the stews wsl!) is the more "extroverted"! I like its effect "wicked" value for money is pretty good (paid 109euros) with exp choice I will ever ca

Eяяаtom's review (This content has been automatically translated from French)

Boss BF-3 Flanger
The last dated Flanger Boss brand: the BF-3. Equally suitable for bass guitar for 2 inputs. In stereo: 2 outputs (to enjoy the effect panner).

Digital technology, unlike its prédescesseurs BF-2 and BF-1.

4 settings: - res: overall level of the flanging effect
- Manual: position of the wave where the effect is applied.
- Depth: depth, intensity
- Rate: Speed

4 modes:
- Normal
- Ultra: more pronounced effect
- Gate / pan: panner effect and add if you want a flanger
- Momentary: the effect is active only if you let your foot pressing the pedal

+ Tap tempo: the tempo is adjusted to the foot after standing in support of 2 sec on the pedal

Site builder: 1 ( ) , 2 ( ) , 3 ( )



Manual ( )


A few samples here ( ) , here ( ) , but especially here ( ) .

The sound quality is average. Very average compared to BF-1, BF-2 & HF-2.
It sounds cold and clear digital. The effect sometimes appears behind the original signal, impreigné not 100%.


We often read that it's a flanger with modern features, however, his perspective was lost as much: no warm & organic sounds. Disappointment, I keep my unbeatable BF-2.

. Fully equipped: 4 tap tempo modes + + 2 inputs + 2 outputs

the -
. all sounds poor

joelatouf's review (This content has been automatically translated from French)

Boss BF-3 Flanger
Flanger modes including a mode that allows you to customize friendly at the foot of the tempo flanger ...

otherwise, it sets the selected effect with 3 knobs, spleen, deep, res manual ... the settings are fairly intuitive, there is a nice fast one.


Edition is easy, relatively simple configuration, ... manual, it will pass.


Used on low, it's nice vraimment, including slap ...

one idea is to set the pace at the foot (or set the tempo of the spleen) and in rhythm of slap on the effect ... I think it changes a lot of whawha car or other filters being used in low to slap. With this flanger, you can really feed her as he wants ... something quiet to something very large and expressive.

the amplitude of the pedal is very impressive, it's really the most versatile flanger.


Used for 1 year (not by me directly)

I like the least it would be the lack of personality of the pedal. It is perhaps a little cold compared to the pedals as the Danelectro Psycho Flange (although generally outperforms the BF3 completely psycho flange)

Finally, I think it's a pedal reference for those who want to use a flanger (I speak especially for bass players) the possibilities are many and varied.

One thing for sure, you can not go wrong buying this pedal.

After that, the quality / price is what it is ... Perhaps it is a bit too expensive for the budgets reduce it, but I think the quality / price is very fair given the quality of the effect.

Boss BF-3 Flanger
There are no evils effects: res (which adjusts the feedback), depth (depth ...), rate (adjust the speed) and manual (adjusts the frequency, yeah yeah, I think)

and four modes: High (large flanger), standard (normal flanger) gate / pan (rotation around the amps down and its in mono), momentary (the effect is applied only when the pedal pressure), there also a kind of tap tempo

two entries: one for guitar, bass and another for two outputs: mono and stereo


This is a setup so simple that the bf-2 but it is not very complicated,


For my part I find that compared to the bf-2 this pedal produces less audible oscillation, cooler and lighter, I routinely prefer the sound of the bf-2 but this is only my opinion, I use peédale with this delay and sometimes a distortion to just increase the oscillations.


I use it for 5 years, it's a quality / price ratio exaggerated given the bf-2, which currently costs a pittance

musejul57's review (This content has been automatically translated from French)

Boss BF-3 Flanger
Boss flanger pedal very comprehensive deph adjustable, rate, intensity of the effect, ultra flanger mode and gate.
Pedal can be used for bass, it has a low connection.
It seems solid and well made.
ability to synchronize with the Fraser tap tempo function.
Output stereo or mono.


Many adjustments are possible with this pedal ... you can get a rotating, oscillating (phaser), gate, one can also make small effects as the chorus.
This pedal is quite difficult to use so Regleg opportunities are numerous.


I find it hard to get his own, but it just may be the modest hardware I have, I play on a rack and a vortex lag ak 100 ...
I made two effects, a chorus sounds clear (ca rounded sound with a mild swing), and a gate effect which gives the impression to bounce sound.
I find this pedal Assé cold.


I use it for 7 months, as far as I am satisfied but it is ultimately not the effect I use typical "Flanger".
I think its price, even if the beast is complete, a little high.
