Had a good play with this tonight and it will retail for £820. This will be available from shops stocking EBS gear but Bernie will do a deal for Basschat members.

This amp does not have all the extra's that the "definition" bass heads have, but what id does have is tone. It also retains the transparency that you expect from an EBS and having tried it with both of my GB's, a Rumour, a KSD and a Fender each bass had its own character shine through.
It also has the EBS responsiveness to playing dynamics. If you snap it snaps, it you thumb it thumbs and if you stroke it strokes.
In a word, fan-f***ing-tastic. If you find the existing EBS amps a little clean for your taste, this is the kiddie.
