Not only DID I go in, I got the full tour! This was back in 1973/74, and they couldn't have been nicer! Was just me and my buddy from Berklee .. then .. we drove out to Niles, IL to the Slingerland Drum Co. We were invited into reception, but NO TOUR. The person chatting with us said Slingerland has FORMAL TOURS, in that you have to take them as they are scheduled ... drat! In 1973/74 Buddy was still with Slingerland of course!, so I was hoping to see some fresh Slingerland 80N Buddy Rich's being built, but it was not to be. The Ludwig tour and personnel were GREAT though!, especially as we just showed up cold without calling ahead.
