The Royale was designed to deliver loud and vivid clean tone with a remarkably responsive, tactile low-end. This is a high-headroom, 50-watt tube amplifier with a powerful EQ, footswitchable boost, tube-buffered effects loop and glorious tube-driven spring reverb – capturing all of the nuances in your playing, both on stage and in studio.
The 5881-loaded power amp in the Royale offers a choice of Class A (35W) or Class AB (50W) operation, as well as a master volume to control sound pressure level. Class A mode delivers the traditional, cathode-biased Supro sound with a bold, spongy mid-range. Class AB provides a grid-biased “California” sound with more scooped mid-range, tighter bass and faster transient response.
Housed in Poplar cabinetry with vintage-inspired Black Scandia tolex and hemp cloth accents, the Royale is Supro’s most dynamically responsive, feature-packed, high-headroom amplifier to date!
