The Spitfire II takes the fire of the original and turns it into a two-channel powerhouse. Channel 1 keeps the classic Spitfire I voicing alive, while Channel 2 brings a bold, vintage-flavored gain with Diamond’s dual volume/gain design. Big, tight, and loaded with lows and mids, it’s everything you love about old-school heads—updated with modern punch.

Shape your low end with the three-way “low focus” switch, and rely on the tube-buffered loop to keep your tone pure and uncompromised. The E. Return control doubles as your master volume when the loop is engaged, giving you effortless command over your sound.

Wrapped in black and tan tolex with a perforated steel grille and solid metal knobs, the Spitfire II looks every bit as fierce as it sounds. Hand-selected tubes and premium components ensure this amp isn’t just versatile—it’s a true workhorse built to roar on any stage.

Diamond, The legends rise

by Chris Loveless

Turn it up—because Diamond is back. I started here in 2008 as a wire jockey and worked my way through every corner of this company. From soldering wires to shaping designs, running production, and steering the big-picture vision—I do it all. Around here, I’m the “Diamond Guy.” And now I get to say it loud: the amps that fueled legends have risen!

Diamond amps have been the beating heart of world-renowned acts, carved into the DNA of countless records, and unleashed on the biggest stages in the world. Born from Jeff Diamant’s vision and Martin Golub’s genius designs, our amps became the benchmark—built tough, road-ready, and dripping with tone. Each one is still hand-crafted, run through a brutal 64-point test, and Guaranteed for Life.

This isn’t just a comeback. It’s a rebirth. It’s fire in the tubes, thunder in the speakers, and a legacy that refuses to fade.

Diamond. It’s what ignites the stage.
