BC Audio Launches the Grand Prix 100

The Dual-Power footswitch toggles the amp’s power section between two and four power tubes.

San Francisco, CA (January 19, 2016) -- Boutique guitar amp builder BC Audio (bcaudio.com) revealed the Grand Prix 100, a meticulously hand crafted all-tube guitar amplifier with a radical footswitch-activated Dual-Power function – the first of its kind. The Dual-Power footswitch toggles the amp’s power section between two and four power tubes, doubling power output and creating a volume boost ideal for soloing.

“A problem nearly every gigging guitar player faces is how to be heard over the band when it’s time to solo, but blend in otherwise,” says BC Audio founder, award-winning guitarist and tube amp master builder Bruce Clement. “The Dual-Power footswitch jumps up the volume without changing anything else on the amp, or in your signal chain. Finally, the performing guitarist has the power to step out in front of the mix, no matter what the situation.”

The Grand Prix 100 boasts two channels, two modes per channel, 3-band EQ, Presence and Depth controls, and an effects loop. It uses 6SL7GT octal preamp tubes, rather than the ubiquitous 12AX7. It is constructed with true point-to-point wiring, US-made transformers and high quality components throughout.


  • 4x EL34 Power Tubes (foot-switchable to 2x EL34)
  • 3x 6SL7GT Octal Preamp Tubes
  • True Point-to-Point Construction (no turret, eyelet or printed circuit board)
  • Channel 1: clean and crunch modes
  • Channel 2: vintage and modern modes
  • Bass/Mid/Treble Controls
  • Presence and Depth Controls
  • Effects Loop
  • 26” Wide “Small-Box” Head
  • Black tolex and bold red racing stripes

The Grand Prix 100 will be on display and available to demo at the NAMM Show January 19-22.

Pricing: $3600, direct from bcaudio.com. Matching 2x12 speaker cabinets are available from $850.

Presets extend the flexibility of an already expansive and easy-to-use reverb.

Intuitive. Great range in all controls. Well-built.

Some digital artifacts at long decay times.


Walrus Audio Slötvå


Walrus Audio is a prolific builder, but, as the five reverb pedals in their lineup suggest, they have a real affinity for manipulating time and space. The beauty of the Slötvå reverb (which is derived from the company’s very similar Spin FV-1 chip-based Slö reverb) is how satisfying and simple it makes dramatic shifts between time/space textures.

With such a flashy flame top, the Silvertone 1445 was built to catch the eyes of department store shoppers.

I don’t know what’s going on lately, but I’m breaking down all over and my shoulder is the latest to crumble. When I was a kid I would practice guitar in my bedroom near a radiator with an ungrounded amp plug and I’d get a zap right through my guitar and into my hands. Well, my shoulder pain is like that now, only without the cool story of rock ’n’ roll survival. I simply woke up one day like this. After a few weeks of discomfort, I figured I’d try out a new pillow, since mine are flattened like a wafer. I ventured out to the mall and, much to my sadness, saw the local Sears store shuttered, with weeds growing up from the sidewalks and concrete barriers blocking the large glass doors. I know I don’t get out much, but, man, was I sad to see the Sears store I’d known since childhood closed-up like that. My wife was laughing at me because apparently it had been closed for some time. But since I seem to exist on a separate timeline than most folks, it was all news to me.
