Hey EADG, I'm in Peterborough too. I've got a Schecter Diamond J that is a great bass and has caused me no trouble. I also e-mailed Schecter once a couple of years ago and got a swift reply. Maybe things have changed.
Where are you taking it locally? I recommend Wyatt at Ed's Music or take it to Wayne O'Conner at Hank to Hendrix.
I'm not going to judge their customer service on one e-mail.. I'm sure things happen.
I know a freelance luthier I usually bring my stuff to. It will likely be either him or Wayne. I've heard Ed's does good work as well, so I have no shortage of options.
