So my former drummer, who also owns lots of PA gear, calls me up tonight to see if I’d join his new 3-piece. So he’s telling me about some gear he’s acquired... and mentions an SVT 810 that he picked up. It’s a 1969. When he opened it up, he found a tag on the inside that he’s assuming is a serial number . - 001 ! Could it be? I’m an Accugroove and SWR user. I really don’t know much about classic Ampeg gear. Is this some other ID ?
