Power section control at your fingertips

NEW! The Bel Air 40 features a series of Power Tube Configuration switches that allow you to reach inside the amp, so to speak, and re-wire the power section in multiple ways. Additionally, a number of unique and thoughtfully designed controls give you the power to finely tune the tonal and dynamic response of the amp.

Like all BC Audio amps, the Bel Air 40 is meticulously hand crafted in true point-to-point fashion, and employs 6SL7GT octal preamp tubes for their rich, warm tone and power-tube-like breakup.

The ToneQuest Report September 2019

"Bruce Clement creates another stellar amplifier.

A big amp with big tone... that truly rocks.

It is rare that we receive an amplifier for review that is as versatile and powerful as the BC Audio Bel Air 40... the Bel Air is one of the most versatile amps we have ever reviewed in these pages.

...outstanding overdriven tone ... a very big tone and a tactile feel to the amp that encourages the best you’ve got to give... The bottom line is, this amp will make you sound palpably better.

The clean tones are vivid and pure, complimenting your guitar brilliantly, and there is enough power to easily stay clean and hang with a band all night long.

The Bel Air’s overdriven sound is utterly classic – it sounds like a vintage amp and not unlike our vaunted ‘68 Pro Reverb cranked, yet the 6V6’s add a smoother character to the amp that is truly addictive.

If you crave a versatile amp that truly can do it all, endowed with intuitive, yet simple controls that create a wide range of ‘vintage’ soundscapes, the Bel Air is your amp. It’s a true performance machine. "

"BC Audio has been turning heads for years with super-cool racing stripe optics, meticulous point-to-point wiring, octal preamp tubes, and bold, original designs that might be inspired by vintage ideas but clearly have their own thing going on sonically and structurally. This Bel Air 40 fits right in with that ethos for a unique take on tube-amp construction.

[The] Power Tube Configuration switches... allow you to re-wire the power section in multiple ways, on the fly, to affect wattage, feel and tonal response. It’s a fascinating approach, and one that can teach you plenty about how tube amps operate. 

[The Bel Air 40] produced a beautiful, dimensional, immediate sound that was loud and perfect for “Wind Cries Mary” cleans that could snarl a little if I really bashed them.

The more you listen, the more you hear... Play this amp and you’ll see what I mean."

"This is masterful work.

The amp’s core tones are punchy and ultra-present...the fundamental note frequencies feel as grounded as bridge piers...while the top end shimmers with animation.

Cranked, the amp has the hair-trigger dynamic response of a good plexi. Meanwhile, the chiming, articulate highs have more of a Fullerton flavor.

The Bel Air 40 is a magnificent instrument. Its build quality is phenomenal. The core tones are lovely. An array of unconventional controls provides remarkable tonal flexibility, not to mention a fascinating lesson in amp topology.

...the amp’s multiple design innovations, unusually labor-intensive build, top-shelf parts, beautiful tones, and flawless construction more than justify the cost."
