Tim rocks. Being able to ring him up and have a chat has proved invaluable. Top bloke, too.
Bob Johnson from legra guitars, also a BK member, is similarly awesome. We spent weeks (months even) going over the designs of my legras in meticulous detail.
Both fellas definitely go above and beyond the call of just basic 'good customer service'.
My amps are all off the shelf with no bias to nationality, though (I have no national bias for any gear, but custom stuff from overseas is impractical) - engl, VHT, marhsall with bogner and orange cabs. I had an MJW for a bit (and entertained a custom off him), but didnt deal with martin much (where I did he was also very good, though).
