I don't understand all this 'wooly' Ashdown nonsense.
I own an Ashdown ABM500 and a MarkBass LM2.
The Ashdown amp is marginally cleaner when set flat than the LM2.
It can be made to sound woolly (obviously), but then so can the LM2!
Try an Ashdown through one of Alex's Barefaced BigOne cabs to hear what the amp 'really' sounds like.
I can only assume that the woolly Ashdown brigade have played them through a 1x15 cab (which is NOT a standalone cab for some styles of music!), and made their mind up from there.
I don't want to argue about this, but I feel there is far to much Ashdown knocking going on in this forum.
From my dealings with them, they seem like a really nice helpful bunch of guys.
And...
Why would the people who were part of the Trace brand put out am amp that is crap?
If anyone doubts how clean an ABM can sound, you are welcome to come and try mine.... through decent cabs!
