The Ampeg Dan Armstrong Plexi is the see-through electric guitar designer Dan Armstrong built with a solid body made from PMMA acrylic, marketed at the time as Plexiglas, Lucite, or Perspex, launched in 1969 and produced only until 1971 before the original run ended. Keith Richards embraced it enthusiastically and became its most closely associated player, with Joe Perry later adopting one as well, while Randy Rhoads used an Ampeg ADA6 Dan Armstrong during his pre-Ozzy years with Quiet Riot, giving the guitar a genuine following across very different eras and styles of rock despite its brief original production window. The guitar's clear body wasn't just a visual novelty; the dense acrylic material gives it a distinctive sustain and resonance different from wood-bodied electrics, part of why it developed a dedicated fan base among guitarists willing to embrace its unconventional look for its equally unconventional tone.
The Yamaha Pacifica 1421 sits at the top of the original Pacifica line developed by Rich Lasner, and is nothing like the entry-level models the name later came to mean. It is neck-through — a maple neck running the length of a basswood body with a maple top — in an HSH layout pairing two DHB1 humbuckers with a DSNB single-coil. Fewer than 250 were built, making it the rarest Pacifica.
