Said versatility increases exponentially when you account for the built-in Ironman Reactive Load output attenuator, which negates the need for a master volume, plus the tube-buffered series effects loop, line-out jack, and handy rear-panel test/adjustment points for both tube bias and screen voltage. Running the gamut from snappy and clean, yet almost blackface-like, tones with the Stratocaster and the Volume around 11 o'clock, to classic thumping British stack grind with the Les Paul and gain accelerated to 2 o'clock or beyond, the Royalist 45 quickly and confidently proved it could do an awful lot of great tricks in the classic-rock, hotblues, and contemporary alt-rock spectrums.
