I have recently had LaLuna Technology accepted on the official Blackstar(TM) non-warranty service centre list and this is the first repair job that came via the Blackstar(TM) website. The amp was making a nasty screeching racket at any kind of volume setting. It was due to one or more dud power tubes. Steve, the owner of the amp went for a complete set of new tubes.
Steve (formally of Electric Rebels) now plays lead for Manchester band Whisky Bullets.
