I got several troubles with my M20d received and used for 6 months. Following the advice of Line support, I contacted the seller (Thomann, Germany), they immediatly organized and took in charge the expedition to Line6 in UK. This was done 6 weeks ago and no news!!! the delay is too too long! I suppose that it is only a software issue, then time to restore the system should not be that long. The system is of course covered by the guarranty (3 years ). On my request, Thomann replied it is still on the way... Are all the people in UK on the way.. to the beach in summertime??? What can LINE6 do to improve the service? I need the soundsystem for coming gigs. What to do, excepted use my old fashioned analogic mixer?
