Diamond Spitfire II is a 100-watt, two-channel all-tube guitar amplifier head made in the USA by Diamond Amplification.
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.
