Randall RD20-112 Diavlo 20W 1x12 Combo
Randall · amplifier
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.
What stands out
“Its strengths are the brutal, articulate gain and flexibility; the caveats are a voicing centered on high gain and a clean channel that is secondary”
— from the community notes
“A tight, crushing high-gain voice with aggressive saturation and clarity for fast, down-tuned riffing and searing leads, plus clean and crunch channels for range”
— from the reviews
“Players value the RD20 Diavlo for its tight, aggressive high gain and strong definition across three channels, a versatile metal amp with usable cleans”
