About the F4

Part of our Vanguard Series, the F4 is the more cost effective sister to the Phantom. Heavy, percussive distortion tones mark the modern but more moderately priced F4. A Diamond product through and through, the 2-channel F4's front panel boasts a dialable "deep" control, and the front panel has a “bright” switch as well.

Front panel controls also include a master volume, and a full range of tone controls (Bass, Middle, Treble, Presence) for both channels.

Like all current and future Diamond Amplification products, the F4 features the highest quality components and construction. The F-4 uses 5 12AX7 preamp tubes and 4x 5881's for its power stage. Each part was personally spec'd and tested by us to ensure maximum performance and reliability, from the transformers to the switches and knobs.

The head features perforated metal grille in the Tolex wrapped front panel, and an accompanying black grille on the back finished in black powder coating. Even the knobs are metal for look and feel. Green LED's light the inside of the head as well.

Priced for the working musician, and everything he needs in one package, the F4 delivers.

The Diamond Process

Diamond began with one goal--give the players the tone and features they need, with the durability necessary to stand up to the abuse of the road. Now Diamond is becoming the benchmark against which all other amplifiers are judged. Diamond’s iconic high-powered amplifiers have now paved the way for a top-down redesign of Class A and vintage redefined amplifiers, proving Diamond to be the all around choice for players of any class or genre.

Hand-crafted in the United States, Diamond builds amps one way - by hand and with the finest engineering available. Each amplifier goes through a 64 point quality control test to ensure reliability and consistency. Using only the finest components available, each amp is individually crafted to ensure you have the experience you want, an amp that delivers - every time - and is Guaranteed for Life.

Diamond products continue to occupy the summit of passionate desires and performance delivered to musicians worldwide as Diamond continues to reinvent what amplifiers should be. To own one is not just a privilege. It’s an invitation to both contentment and creation.
