Similarity
citedBlended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

The ENGL E633 Fireball 100 is a 100-watt all-tube 2-channel guitar amplifier head from ENGL Amplification, Germany. Two channels — Clean and Lead — deliver ENGL characteristic tight, aggressive high-gain saturation at 100W stage output. The Fireball is one of ENGL core metal and hard rock platforms, known for its extremely tight low-end response, note clarity at high gain, and aggressive attack. The 100W version extends the Fireball voicing to full stage wattage.

The Randall RD20-112 Diavlo is a 20-watt 1x12 valve combo, the small-format member of the Diavlo line. At 20 watts it reaches its power section at volumes usable in a room, which the 100-watt Diavlo head cannot, making it the practical choice for recording and small venues. It shares the all-valve construction that distinguishes the Diavlo series from Randall's solid-state history. It suits metal and hard rock players who need valve gain at manageable volume.
