Show full description »

Now, keyboard players the world over have a really good reason to be afraid of their bands' guitarists! At the press of a footswitch, guitarists the world over can get some truly classic organ sounds such as the Mellotron flutes of The Beatles' Strawberry Fields Forever, Led Zeppelin's Your Time Is Gonna Come and Jon Lord's classic Deep Purple Highway Star organ sounds.

The C9 will transform your instrument into a convincing full body, electric organ or vintage electronic keyboard.

For each preset chosen, it also provides precise control over important elements of that sound’s sonic fingerprint like percussive click, modulation, attack/sustain, drawbar setting or high frequency content. Blend your dry signal to create beautiful layers. Lovers of classic organ and keyboard rejoice!


Controls the volume of the untreated instrument at the ORGAN OUTPUT jack.


Controls the overall volume of the ORGAN preset.


MOD controls the speed of modulation. Modulation can be completely turned off when MOD is set fully counterclockwise. The type of modulation is contingent on the preset selected. The different types of modulation available are vibrato, tremolo and chorus. See the preset descriptions for modulation type.


CLICK controls percussive click level. It was designed to simulate the harmonic percussion effect on classic B3 and C3 organs. The click is added to the very first note or chord played. The click will retrigger only when current notes have been released and their amplitude falls below a threshold. For most presets, CLICK controls parameters unique to the preset. See the preset descriptions for details.


Press the BYPASS Footswitch to toggle the C9 between buffered Bypass and Effect mode. The status LED lights when in Effect mode. 


DRY outputs the signal present at the INPUT Jack through a buffer circuit. The dry signal is outputted regardless if the C9 is in Effect or Bypass mode. The DRY Volume knob does not change the volume at the DRY Output jack.


ORGAN outputs the mix set by the DRY and ORGAN controls.


  1. Tone Wheel - Classic tone wheel-esque organ sound. MOD type:  Chorus. CLICK sets level of click sound.
  2. Prog – Paying homage to the massive sound of Keith Emerson of Emerson Lake and Palmer. MOD type:  Chorus. CLICK adjusts the level of an interval of a fifth and an octave below.

  4. Shimmer - This preset is based on an effect made popular by Brain Eno and Daniel Lanois. MOD adjusts the attack time. CLICK controls the sustain amount.

Note: On presets 2, 3, 5 and 7; the CLICK knob is a volume control that works independently of the main ORGAN volume knob.


  • C9 has buffered bypass.

You can also mix the sounds of the C9 with those of the B9 pedal, and have a rich sound blending both organs, simply by using a A/B Y -style footswitch, such as the Morley ABY pedal.

Price Matching

Dolphin Music brings you the best music gear at the best price. We are committed to superior customer service and have extensive product knowledge. However, in today’s market we may not always be aware of all the price fluctuations of the products we sell. So, we offer competitive price matching.

Please fill in the following form to request a price match.

What prices we will match?

We will compare prices for new, direct from manufacturer items, excluding any add-ons, options, or other special features which may affect price.

The item must be new and must be the exact same make and model (ie, the same size, version, etc.).

Since our postage charges are lower than most of the shops, the comparison price must be a "delivered cost" to the consumer.

If we are unable to verify the previous condition, we will notify you that we require additional information to verify the Price Match request. Our goal is to make this policy simple and hassle-free. We are committed to responding to your requests quickly.

The price you have found must be the Internet Retailer's regular, advertised price for a current and available item. The price you found cannot be a closeout, discontinued, blemished, year-end, inventory reduction, or any other type of advertised sale price.

Price Matching requests may not be combined with any other promotional discounts, specials or other price incentives.

Prices and price sources you have found which do not meet the above criteria or in which incomplete or inaccurate information is provided to us, will not be approved for our Price Match.

Please select your country/region

Choose the region you are shopping from to view products in your currency.
