Review ENGL Fireball 100 100-watt Tube Guitar Head

The ENGL Fireball 100-Watt Tube Guitar Head, model number 251694200085 (E635), is a high-performance amplifier designed for professional guitar players who seek authentic tube tone and versatile sound shaping capabilities.

At its core, this amp head is powered by four 6L6 and four ECC83/12AX7 tubes. These tubes deliver a rich, harmonically complex tone that is reminiscent of classic rock and blues recordings. The 100-watt output delivers plenty of power for gigging and recording, while retaining the warmth and depth that only tube amplifiers can provide.

The ENGL Fireball 12AX7 preamp section offers a wide range of tonal options. The three-band equalizer allows for precise adjustments to bass, mid, and treble frequencies. The presence control adds brightness and clarity to the sound, while the depth control adds a subtle, thickening effect. The gain control ranges from clean to full-on distortion, providing a versatility that can cover a wide range of music styles.

In addition to these controls, the ENGL Fireball also features a selectable negative feedback loop, which can be engaged to tighten up the bass response or loosen it up for a more vintage sound. The global reverb control adds a touch of ambiance to the sound, while the global master volume ensures consistent volume levels between channels.

The Fireball 100-Watt Tube Guitar Head is built with high-quality components and rugged construction, ensuring durability and reliability on the road. The chassis is made of powder-coated steel, and the front panel is protected by a heavy-duty 16-gauge steel grille. The amp head also features a standby switch, which allows for extended tube life and reduced power consumption when not in use.

The ENGL Fireball 100-Watt Tube Guitar Head is a versatile and powerful amplifier that delivers authentic tube tone and a wide range of sound shaping capabilities. It is an ideal choice for guitar players who demand the best in tone, reliability, and versatility.
