Want the Factory look for your 29LX? We have it all for you here. This upgrade will have the same great Echo board we sell with the NEW Switch and Black Factory Knobs that match your radio like a glove. All parts are factory Cobra so you don’t have to worry about some cheep part being used. If you like Echo and want it to sound clean and clear then you will want us to install an RF Limited Turbo Echo for you. This Echo board is clean and also has a built in modulation amp for more power without distorting like some of the cheaper ones do. It will be professionally installed in your radio just like it came from the factory that way. Echo board will be securely mounted to the chassis of the radio and all wiring ran through the factory wiring harness. if you have a special request for the control to be mounted in a specific place please let us know at the time of the order.
