BC Audio Launches the Bel Air 40 Guitar Amp

An all-tube guitar amplifier with a unique set of front-panel controls that let the player reach inside the amp.

San Francisco, CA (October 11, 2018) -- Boutique guitar amp builder BC Audio (bcaudio.com) revealed the Bel Air 40, a meticulously hand crafted all-tube guitar amplifier with a unique set of front-panel controls that let the player reach inside the amp, so to speak, and re-wire the power section. The Bel Air 40 features four 6V6GT Power Tubes, two octal 6SL7GT preamp tubes and a GZ34 tube rectifier, and is built with true point-to-point construction – no turret, eyelet or printed circuit board. Power ranges from 40 watts to under 5, depending on how the Power Tube Configuration switches are set.

“We're used to seeing lots of knobs and switches on guitar amps. Normally, those controls operate almost exclusively in the preamp section, while the power section just sits there amplifying what comes its way. This amp turns that approach on its head,” says Bruce Clement, BC Audio founder, award-winning guitarist and tube amp master builder. “The Bel Air 40 gives the player control over what's really going on in that mysterious part of the amp that you can't normally touch, the part that is the key to great tone – the power section.”

Power Tube Configuration Switches:

  • "Quad/Pair" switches between two or four 6V6s. This serves as a half-power switch, with the Quad setting providing more girth and punch.
  • "Pentode/Triode" reduces power by about half in Triode mode, and also noticeably changes the tone and feel of the amp, with Pentode mode being tight and clean, while Triode mode feels smooth and loose.
  • "Fixed Bias/Cathode Bias" changes the dynamics of the power section, cathode bias mode being slightly lower-powered, more compressed and a little bit browner.

More Power Section Control:

  • "Presence" brings out the chime and sparkle, while "Cut" tames the highs generated by overdriving the power tubes.
  • The 3-way “NFB” (Negative Feedback) switch alters the damping and open-loop gain of the power section, with the Zero NFB setting being the most raw and touch-sensitive.

Preamp Section:

  • The Bel Air 40 is a non-Master Volume design. It uses 6SL7GT octal preamp tubes for their rich, thick sound and power-tube-like breakup. Controls include Volume, a 3-way Bright switch, Body (for tightening up the low end), and a three-band EQ that can by bypassed for the purest exploration of the power section's overtones.

Pricing: $2900 (pro-net), direct from bcaudio.com. Matching 2x12 speaker cabinets are available from $850.

Kenny Greenberg with his main axe, a vintage Gretsch 6118 Double Anniversary that he found at Gruhn Guitars in Nashville for a mere $600. “It had the original pickups, but the finish had been taken off and the headstock had been repaired. So, it’s a great example of a ‘player’s vintage instrument,’” he says.

On his solo debut, the Nashville session wizard discovers his own musical personality in a soundtrack for a movie that wasn’t, with stops in Africa and Mississippi hill country.

Kenny Greenberg has been Nashville’s secret weapon for decades. He’s the guitarist many insiders credit with giving the Nashville sound the rock ’n’ roll edge that’s become de rigueur for big country records since the ’90s. It’s the sound that, in many ways, delivered country music from its roots to sporting events.
