I'm wondering about the tone of vintage Marshall amps vs handwired replicas done today by experienced amp builders. I've seen the schematics for vintage Marshalls posted online. So, that makes it seem like a current day builder could 1:1 reproduce a vintage Marshall and build an amp with the exact same sound. Then again, perhaps not. Is there anything that makes a vintage Marshall tonally superior compared to what an amp builder could make these days with a remake/clone? I wonder if there are certain parts, materials, etc. used back then that aren't available anymore that make the old amps somehow sound better, or if the replica would sound essentially the same as the original.
