NAMM 2011 PRESS RELEASE: The all new Royal Atlantic wears an undeniable crown in the TransAtlantic fleet for delivering all this Tone with a big power gut-punch and three amazing Modes of footswitchable performance.

Packing 100 watts of EL34 Brit-voiced attitude, this Atlantic takes everything you love about Fullerton and Liverpool and brings it all together with rich, chest-thumping high gain in a way only a MESA can.

The RA 100 also features our revolutionary new Channel Assignable Power Soaks that will redefine for you the concept of Power Expression and put you in total command of playing volume independent of power clip. At last… dial up a preamp sound in each of the Modes and crank in the perfect amount of power saturation at the right volume - and footswitch between them seamlessly!
