Review Electro-Harmonix B9

Definitely a guitar and an organ sounds pretty good in any concert. With a simple layout the Electro-Harmonix B9 Organ Machine is to the point with no exaggeration. The click knob has five control variations that allows access to manipulate and control the ratio of the organ signal and the dry signal. A knob is also provided for the click and mod control. Moving through nine variations on the organ type this larger knob is provided on the left crosswise of the pedal and there are some independent outputs on every signal which is an added advantage.

EHX advocacy…

Recommendations for the best tracking were provided by the EHX. To not get a fake sound or distorted, the EHX suggests you to place the B9 at the beginning in the signal chain. When I tested this after a full tone Drive-2 MOSFET I did feel an edge when the B9 was placed earlier at the chain. One oddity though was that I fixed the B9 at the “Full Drive 2” to assist the signal and the MIM Fender Strat was used. The lower output gave the B9 the right signal.

In the knob function first major setting I investigated was jazz. Radiant than I had expected, it did contribute to hints of McDuff’s or the overtones of the Hammond B3. The mob knob in the preset ensured control of the speed with effects like a rotatory speaker. When I continued to play on organ notes, I had to make the adjustment of EQ a little more than the usual on my “Deluxe Reverb”.

Among all the preset tones in the B9 Harmonix the one that sounds the most majestic is the cathedral settings. I started up the ‘verb on the Deluxe’ reverb pedal kit on slow and soft chord. This have a soft bite, the mid-range on the upper level of the B9 brings in mind the enlightened sound created by Deep Purple and Yes when a compressor was combined. There is a knob feature that can be rotated and clicked for the octave settings to add higher harmonics.

While we saw the regal of the tones, the most retro of the settings are the two at the end, bell organ and continental, sounding the most skittish and frisky. Reproducing tone of Ray Manzarek tone, the continental setting creates tones simliar to “Light My Fire” and “A-Gadda-Da-Vida”. Reasonably inadequate for the keyboard player, since the tones are not compelling as much, it sure suggests the 60’s pop culture and amazingly composed atmosphere. The setting of bell organ is typically the organ style: Hammond style. The knob provided allows for a dial setting of the adequate volume of chime.

With all the extravagant and remarkable features of the B9, it has its share of limitations as well. When on the organ setting there is a faint tone of the guitar tone that is undoubtedly heard. In spite of the fairly wide options that the preset options provides, the most restraining factor would be the missing EQ controller. This is indeed by far a limitation on its features.


The B9 electro Harmonix adds a multidimensional, sensation of touch, texture and tone. This is evident if you are aware of the B3 and would distinguish it from the Melosonic. The ability for the B9 to deliver workable sounds is by far the most advantageous.
