Electro-Harmonix B9 Organ Machine
Polyphonic pedal that emulates the sound of the Hammond B3 organ. 1 guitar input, 1 output Organ for mixing the processed sound and the direct sound output 1 DRY (direct sound) to go out on another source.

5 buttons:

1.1 9 position selector that lets you choose the type of sound emulated: the standard hammond organ sound through the church organ. We find all the classic sounds.

2.DRY can manage the volume untreated (the guitar) 0 to a unit volume (the same level as the original sound)

3.ORGAN: volume of the organ

4.MOD: modulation effect by allowing the sounds (the first 7 memory) to get a more or less pronounced leslie effect or a tremolo effect

5.CLICK: Manages the attack: 0 the keyboard sound that emerges is rather mild and increasing click, a percussive sound comes at the beginning of the notes played.

Finally comes the pedal as often with electro harmonix with his food, very helpful and avoids an extra expense for some.


Very easy to use, you plug it puts everything at noon and it is left for the first tests.

I will come down on the sounds.

The pedal takes a little getting used to, tracking is very good according to use: as stated on the website electro harmonix, a compressor pedal before and using the bridge pickup provides good results without stall.

Attention must avoid vibratos left hand (for right-handers) or we panicked a bit b9.
Also notice to shredders and fans sweeping: the ultra fast game is a bit beyond the capabilities of the pedal itself with attacks treated, it does not go well.

In a few minutes, the inconveniences fade and adapting the way we play, you get there.


Well, this is where the real fun begins:

The sound is simply amazing both in agreement that single note. It feels really hear a hammond organ sound, the sound that is found in all our old vinyl records of the big time. Deep purple fan, take you on!

9 sounds are usable for me with a preference for sounds and Full Fat, Cathedral and Jazz.

Mixed with the sound of guitar really lets you feel like playing the organ and who also has a looper can really have fun to create accompaniments and replay behind.

Mixed with the guitar sound is a solution that enables on sounds crunch to find a saturated depth to play Deep Purple songs, it's great.

Note for chaining, which must be used before any distortion pedal.


After a week of use, I have used it yesterday in rehearsal and the rest of the group was amazed as I at first listen, forcing me to integrate it into my pedalboard for the next concerts.

I do not know if I would use it a lot, love the guitar to guitar sounds but anyway I am very happy with my purchase and it will pass on some live fun a little more surprising the public .

Electro-Harmonix B9 Organ Machine
9 types of organ "classic" await you on this pedal, digital and buffered bypass ...
its not feel good at first ... but that's not counting on the pro side of EHX ....
one in and 2 out (dry and dry + organ) in case the organ we want another amp .... well thought out!

9v 100ma current and


the manual is more or less useless as the pedal is easy to understand.
Mod and click buttons are there to add the chorus or vibrato or a touch of acute one for speed and one for depth are the organ are typed and can all find useful.
care must be taken in dry (if you want the guitar) and especially because different organ presets do not all have the same volume and or attack is little surprise that when we pass from one to the other.


devilishly effective! to the low bottom end is EXCELLENT! to sustain is incredible (good on the other hand when notes eventually stop is not very musical) of all beauty in agreement as single string (unlike the organizer)
with my strat is madness!


since yesterday (note: it has just arrived at the mag for those who do spineless ...)
Asses is confusing not being able to do His organ sound we condemned the 9, but the reflection is much richer than the organizer who still for his deffence the "lag" button that Wonderland ...

I had an organizer and I sold it to me says it all.
