From Rivera Amps
Heavy in tone, light in weight, easy to use, and very portable, our R Series of all-tube combo amplifiers evolved from our M/S Pro Series combo amp. They are available in two sizes, with a 1-12" or 2-12" custom Celestion speaker configuration, in 30-watt and 55-watt (1-12" only) or 100-watt power (2-12" only). R Series amps feature our legendary pair of independent and differently voiced channels, with footswitchable boost on each, delivering four sounds at the tap of your toe.
From British amp tones on Channel One, for those sultry crunch rhythms and leads, to the warm tweed or blackface American tones on channel two, the versatility to bring out the best in any style is there. Built-in Hammond 3-spring reverb provides a smooth and sweet fill, and a super-quiet active effects loop with level controls lets you utilize external effects quietly and allows you to mix in that extra spice you need for your individual style.
