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 Peavey 6505 II is a 120-watt all-valve two-channel head, an evolution of the legendary 5150/6505 that became a cornerstone of modern metal and hardcore. With six 12AX7 preamp tubes and 6L6 power, it delivers a tight, aggressive, high-gain rhythm channel and a searing lead channel, plus added features over the original like channel-independent EQ and an effects loop. Its saturated, cutting gain defined countless heavy records.

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.
