i was expecting something else to be written from bill on that forum than what i actually read, i don't think its all that bad.
regarding comments about the inductance, he maybe right.. i know my way around electronics. though what is certain is adding copper tape will have some sort of affect on the inductance and definately the sound of the pickup. if tim reckons its makes the sound worse, i believe him.
the last paragraph bill wrote is just rudeness really... maybe he is a bit sour, who knows, its certinally unprofessional. saying something negative in public never usually comes off without you looking silly. as an experienced engineer i'm surprised he tried it.
no one else is really copying the aspects of Tim's business model which work well, just parts of it. i'm surprised no one else has 'got it' yet, it seems obvious to us.
