San Francisco, CA (November 4, 2016) -- Boutique guitar amp builder BC Audio is expanding its critically acclaimed Octal-Plex series of guitar amps based on 1960s British plexi circuits that have been adapted for octal (8-pin) preamp tubes and built with true point-to-point construction techniques to include custom 100-watt versions. Each amp can be customized with a number of circuit variations and optional features.

“I’m very pleased with the Octal-Plex series. It’s an amazing combination: the big sound of octal preamp tubes, the clarity of point-to-point wiring, and those simple, powerful plexi circuits,” says BC Audio founder and award-winning guitarist Bruce Clement. “The 100-watt amps now complete the plexi picture.”

Customers are invited to choose between JTM45/100-style or Superlead-style preamp circuits, in Lead or Bass specs. Other circuit variations and mods are available, along with a menu of pre-configured options. Mr. Clement often works with individual customers to tailor the amp to their specific needs for a truly custom, handcrafted instrument.
