About the Rivera Pubster 25

The Rivera Pubster 25 puts 25 watts of 6V6GT power through a 10″ Rivera Celestion Vintage Gold speaker. The amp uses two ECC83 preamp valves. As a result it is both reliable and easily accessible when it comes to service. It comes with a foot-switchable Accutronics 3-spring mechanical reverb and a 2-function foot-switch.

Also, this amp has an effects patch loop with an external speaker jack and a line output for recording.

It also has a single 3-band EQ section. A foot-switchable boost comes with its own gain control, as well as a second master volume to regulate the level. This lets you go from a clean rhythm to a fat lead solo at the tap of a toe. A lovely little amplifier all round.
