Hammond Dissection - The A-100
As most Hammond owners know, the Hammond is a complex organ. It is no simple task to fix or modify a Hammond. Seeing all of those wires can be extremely unnerving and formidable. My goal here is to provide a repository for highly detailed photos of the insides of a Hammond. This way, people will know what they're in for when they take the back off and try to fix that broken drawbar, or that stuck vibrato. Reading the procedures in the faq along with looking at these pictures should give a better idea as to what to look for. Over the next couple of weeks, I intend to improve this by adding more pictures and organizing it much better. Thanks for stopping by - please send comments and suggestions, and *especially* suggestions for pictures you would like to see, or you would think others would like to see to me at bdodds@bbnplanet.com..
