(Re-release in 2014 after performance modification) 


CW and SSB!!



Yes, the FX-4 is going to be re-released!! We had a limited production run and we sold out very very quickly. The demand was so much, we didn’t even make a dent in our waiting list. However, we have elected to make some fairly substantial updates on the unit prior to a mass production run. We know we have a winner with this unit and want it as close to perfect as we can get it. Simply put, we were not satisfied with the Chinese production so we have elected to handle it ourselves. We are proud of the LNR brand quality and will not compromise it under any circumstances.  If you purchased an original FX-4, we will offer you an update when the updated units become available.  Here is an updated picture and it will be a very sharp black color. Other pics are on the Facebook page. We still plan to offer it for purchase for $450 and you can add your name to the wait list which can be found at the bottom of our purchase page.
