RX Series RX120RH 120W Guitar Amp Head Huge sound in a smaller package is the best way to describe the RX120RH from Randall's RX Series. Their mission to deliver a more affordable guitar amp that achieves the tone of much larger combos and stacks has developed into quite a powerhouse. The RX tone circuits are designed to achieve the modern Randall tone that delivers plenty of tight lows as well as enough top end sizzle to satisfy any metal monster. The result is an overwhelming sound that may change your definition of the modern practice amp. Built-in spring reverb. RX412 Cabinet Randall's RX412 cabinet delivers huge sound that rivals the tone and power of much larger, more expensive boxes. Much of its power comes from the four 12" Randall Jaguar speakers, but throw in the RX tone circuits and it delivers plenty of tight lows and enough top end sizzle to satisfy any metal monster.
