Thank you for your compliments.
Thusly encouraged, please allow me to continue.
Part of the reason for the non-descript appearance of the building and 'What Lies Beyond' is that the neighborhood is in a...well, how shall I say it? A war zone. Non-descript is much better and enhances survival. Directly across Richmond Terrace are dry docks, where the Staten Island Ferries were occasionally brought in for repair, retrofitting, etc. In the winter, the wind blows so cold off of the Kill Van Kull you'd swear you were on Lake Superior. Now, on Staten Island, you have one or two other companies that are legendary. One of the others is Mandolin Brothers, up on Forest Avenue. Perhaps not so coincidentally only about a mile or so away from DiMarzio, also in the magical town of West Brighton. I say magical, because on some very nearby streets where DiMarzio is located, you need to utter incantations to avoid getting robbed, shot, or both. Both companies, especially since both are in the music industry, had their share of LARGE egos running amok in the countryside during the days when they were the big kids on the block and the only game in town. To be a fly on the wall in both locations was quite 'enlightening'. To be fair, a good number of their customers had large egos, too. Mix the two, expose to the public, and let the games begin. Picture in your mind a combination of The Three Stooges, "It's A Mad, Mad, Mad, Mad World", and "Dallas" - all rolled into one flaky "double cream" filled pastry.
The economy and the internet, have changed things significantly for both of them.
But I digress.....
If you want a picture of the inner workings of DiMarzio, look no further than Seymour Duncan. Their website, especially the Q & A section, is a short class in pickup making. There are photos of the interior of SD's factory that are the functional equivalent of DiMarzio's facility, only larger. Some of the other pieces of the DiMarzio puzzle can be answered this way: know your product intimately, know your suppliers / vendors, and have more than one source. Some years ago, DiMarzio's main plastic and metal parts supplier imploded without warning, forcing DiMarzio to rescue their tooling and find other molding and fabricating shops to pick up the slack.
