Critic Reviews

RD20H Review: The RD20H also would be a decent choice for a cover... | Randall | Guitar Amplifiers | Reviews @ Ultimate-Guitar.Com

ultimate-guitar.com

Randall's RD20H from the Diavlo series surprises with its versatility beyond just metal. The amp shines with a commanding tone reminiscent of the revered 5150, and its superb build quality ensures reliability. The 20-watt head delivers pristine cleans and brutal, refined distortion, making it ideal for a range of genres. However, the footswitchable boost can introduce noise, a minor setback in an otherwise stellar performance. Despite shared EQ and a simplistic feature set, it offers significant bang for your buck, proving itself a worthy contender against pricier, high-gain amps. An excellent choice for those seeking powerful tone without breaking the bank.
