Ashdown - everytime time I've had to contact them I received service over and above what I expected.
I bought a GB Rumour from a member here, however the Bass was with Bernie being serviced. He rang me to ask how I wanted it set up, I mentioned that I liked light strings - it was wearing 45s at the time - even though I wasn't actually giving him any money he still bought a new set of light strings, fitted them and set the bass up.
Dawn at Status - every time I've spoken to her she has sorted my query without any issue.
I've only dealt with Warwick once. Their rep was rude and unhelpful - I won't miss an opportunity to tell others.
