A couple of weeks ago, MAKE photographer Gregory Hayes, designer Michael Silva, O’Reilly Web Producer Tony Quartarolo, and Jake Spurlock attended Amp Camp, just up the road from the O’Reilly offices in Sebastopol California. What’s Amp Camp? Glad you asked. A few years ago, Dana Brock held Speaker Camp, where 20 or so friends hung out in his workshop for a day and built speaker enclosures. Building on the success of that, he and Nelson Pass decided to do it again and have a day, in the middle of the wine country, to build amplifiers.
