NO LONGER AVAILABLE - Euro CB EC-990 Echo Chamber - 6 pin plug (for most modern CB's) YouTube Demo Video!   
   Product #2072   
  £0
Inc. VAT


21/09/17 : SORRY THESE ARE NO LONGER AVAILABLE

An excellent quality echo chamber for use on standard 6 pin wired CB's : Midland, Alan, Albrecht, Team, President, Maycom, Danita, Lafayette, Maas, Kernow, Maxon CM70, Magnum, Moonraker (and many others)

IMPORTANT :
Because of the complications involved with getting the EC-990P6 (the factory wired 6 pin echo chamber) working on all radios, this is a 4 pin one where we rewire the output lead (the one that goes to the CB) with a standard 6 pin plug, but you will need a 4 pin mic to plug into the front of it. We do a version of this 6 pin wired EC-990 that comes with a new mic here : Standard 6 pin wired EC-990 with dynamic mic and this is the option most people take but if you already have a spare 4 pin mic that you could use with this echo chamber it probably makes sense to buy this version instead.

However, as there have been various configurations of the 4 pin wiring over the years, we will need to know what CB your mic was originally used with. You must tell us this at the time of ordering by putting the CB make and model in the "special instructions" box provided in checkout. Failure to do this will lead to delays in despatch.

99% of 4 pin CB's are one of two different wirings, "Uniden/Cobra" or "Cybernet" but there have been a handful of others over the years - this chamber is available in versions compatible with mics from both the main wirings but if your mic is wired to one of the handful of others these will not work and you would be better off purchasing the "Standard 6 pin wired EC-990 with dynamic mic" mentioned above.

If you want to check what wiring your mic has, you can use our contact us form so we can check and tell you.


These are great fun and highly adjustable so you can have just a hint of echo or go completely over the top - or anything in between!!

The echo delay control has a wide range of adjustment and creates a "reverb" effect when set to the lowest delay time... the more you increase the delay time, the more time there is between "repeats" so you can go through whats called a "slapback" effect right the way through to a classic long repeat time Echo. (Watch the video below to hear it in action!)

    Main Features:
  • Adjustable echo level and echo delay time
  • 10 segment LED output meter
  • Switchable roger beep (single beep ; K-tone "dah-dit-dah" ; beep off)
  • High quality metal case - very sturdy
  • Supplied with earphone for monitoring of your echo in real time
  • On/Off switch
  • Update January 2017 : We now supply the EC-990's with a bracket & sides screws kit, previously an optional extra @ £4

    Compact size (case size, excluding controls on the front and connections on the back) :
  • 105 mm Wide
  • 32 mm High
  • 112 mm Deep


Here's our Youtube Demonstration of the EC-990 Echo Chamber (applicable to all versions)

I originally made this video for eBay where we also sell these (at a slightly higher price than on this site), so please excuse the "ask seller a question" references etc!
