In a few days, I may very well be the proud owner of an Ashdown MAG300 head (or ABM500 EVO II if Dad is feeling particularly generous this Christmas season), and he was told by the people at the guitar/amp store that Ashdowns are amazing amps but that they're incredibly unreliable and prone to fizzing out without warning and after a very short period of time. Now, this store is a small business that has been around for decades and they know what they're talking about, at least when it comes to basses and guitars. I've also heard a lot about Ashdown's amp problems in the past couple years, with things blowing up and such. Now, I emailed them when I was researching amps and asked about this problem, and they told me they'd figured out what it was and fixed the problem, and now all their amps are fine and it doesn't happen anymore. Is this true? Or are Ashdown amps still prone to failing spontaneously? Have they fixed the problems that the amps were having in the past?
