Art Thompson sizes up the Royal Reverb for Guitar Player Magazine:
“With or without effects, though, the 1650RT’s clean-to-overdriven envelope provides options aplenty for rhythm and lead playing, and a sweep of the guitar’s volume knob is all it takes to go from mean to pristine. The Bass and Treble provide for basic EQ tweaking, but this is kind of amp that gets its tone on easily and doesn’t need anything further to sound good.”
“The 1650RT Royal Reverb is an interesting and inspiring amp that stakes out its own turf in the mid-power combo market. If you think you’ve heard it all, give this new Supro (or any of its siblings) a try. You may be pleasantly surprised by what you’ve been missing.”
