I have one of the first acoustic image contras [s/N 00035]. It has been a great little combo, very realistic sound for the upright or practice amp for electric bass. So, I am on a gig and the woofer stops woofing and all I am getting is sound through the 5". So I finish the gig playing real acoustic [now I know what those old cats went through for decades! ] Anyway I have called numerous times [had to leave messages] emailed directly and emailed through their site and have not received one response about getting it fixed. No one has returned the calls or emails - possibly the worst service I have ever had - and I have had some lousy experiences. Is it me or is there some trick to getting these guys on the horn? Thanks - in distress!
