BC Audio Introduces the Octal-Plex Series

The amps are based on 1960s British plexi circuits that have been adapted for octal preamp tubes.

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.

Guitars are the best. We love them. It’s fun to fall in love with a guitar at a store, buy it, and proudly bring it home. But we’ve all been there … where after a month that new guitar is just not playing as good as it was before. As guitar players, we know what feels good and what feels bad when it comes to playability. Maybe you have setup preferences that you like on all your guitars, or maybe you want to experiment with changes to your setup?
