Preset Descriptions
Fat & Full: This sound adds an extra octave below and above to make your guitar sound twice as big. Fills out any band in an instant. MOD Type: Chorus.
Jazz: This preset has the cool, smooth jazz tone reminiscent of the late great organist Jimmy Smith. MOD Type: Chorus.
Gospel: This preset has the upper octave drawbars added to capture that great soulful organ tone. MOD Type: Chorus.
Classic Rock: This preset captures the classic rock sound of songs like Procal Harum's "Whiter Shade of Pale." Add a touch of distortion for a classic dirty organ. MOD Type: Chorus.
Bottom End: This preset has the lower draw bar sound. Perfect for adding bottom to your guitar or playing B3 bass sounds. With the CLICK control up you can lay down a bass line like the one on Sugarloaf's "Green Eyed Lady." MOD Type: Chorus.
Octaves: This preset uses the fundamental tone plus one octave above. This sound is great for songs like Led Zeppelin's "Your Time is Going to Come." MOD Type: Chorus. CLICK control adds not only key click, but higher harmonics.
Cathedral: Turn up the reverb and you are at the seat of a giant cathedral organ! Psychedelic rock tones easily pour out. MOD Type: Tremolo. CLICK adjusts the tremolo depth.
Continental: This is the classic combo organ sound similar to classic songs "96 Tears," "Woolly Bully" and "House of the Rising Sun." MOD Type: Vibrato. CLICK controls vibrato depth.
Bell Organ: If you crossed an electric piano with an organ this is it. MOD Type: Tremolo. CLICK adjusts the amount of bell or chime added to the sound.

Great sounds

By Rob

Comments about Electro-Harmonix B9 Organ Machine Guitar Effects Pedal:

This pedal does what it says it does it's gonna do. Life like organ sounds - nine distinct "variations". It's an amazing combination of compression and sampling. The sustain goes on for a VERY long time. It does seem to respond somewhat to dynamics which I suppose a Hammond without using the volume pedal would not - but that's probably a plus IMHO. I bought the pedal after watching what I believe was the official video and it sold me. Once at home it reacted similar to the video. The idea of this pedal, if you want to mimic an organ, is to hold notes while playing others. If you play it like a guitar it still sounds like an organ but less like an organist - if you follow me. Having said that - if you turn up the guitar output and mix with the organ output you get some ridiculously cool sounds that I've not heard from any other pedal. So all in all lots of great sound choices here. One negative I discovered(hence 4 instead of 5 stars) and I wouldn't call it major; it seemed some (let's say) bizarre chord note choices would create some overtone anomalies and pitch warbling. Like the doctor says when you tell him it hurts when you bang your head against the wall - "so don't bang your head against the wall". I think if you keep the notes and intonation reasonable maybe that wouldn't occur...? Also, haven't used it to play out yet and imagine I might have to adjust controls for different song settings so maybe some fiddling between numbers involved - not a problem in a studio setting tho... Finally, I'd definitely recommend this pedal to guitarists looking to broaden their sound and add to your arsenal. You won't be disappointed!

    Comments about Electro-Harmonix B9 Organ Machine Guitar Effects Pedal:

    I was introduced to the B9 pedal through the EH video. Based on what I heard and saw in the video, I did some additional research on the internet and at my local GC. I also researched the C9 and the Key 9. Based on their tones and features, I decided that the B9 would probably best fit my needs. I am a rhythm guitar player and I sometimes find that the lead guitar player and I are essentially playing the same rhythm parts when the singers are singing. However, with this pedal and a touch of the foot switch, I able able to bring a whole new dimension and sound to the mix. Every time I use the effect, my band mates get a great big grin and I see the audience wondering -- I don't see an organist, where is it?" I only use it in select songs so the sound doesn't get overused. I have not been disappointed with this purchase.


    Poor quality, great sound.

      Comments about Electro-Harmonix B9 Organ Machine Guitar Effects Pedal:

      First one didn't work at all right out of the box. Second one broke a little over a year after purchase. Like every other EH product I've bought, this unit sounds amazing but the quality is garbage. I'm tired of sending every pedal I buy from EH to NYC to get fixed.
