The Supro 1650RT Royal Reverb is a retro-modern masterpiece that serves as the flagship tube amplifier of the Supro line. 
 
Designed as a reissue of the classic 1960s amp, it retains the vintage charm while introducing modern features for superior tonal flexibility and ample headroom. The Royal Reverb features a unique signal chain, where the tremolo effect follows the tube-driven spring reverb, creating an ethereal, wobbling soundscape that envelops your every note.
This versatile amplifier boasts a 3-way 35/45/60-watt rectifier switch, allowing you to choose between Class A mode at 35 watts and Class AB mode at 45 or 60 watts. These options provide different levels of headroom and different voicings for the tremolo and reverb effects. 

Independent treble and bass controls give you the power to shape your sound to perfection. Whether you're a home player or a stage performer, the Royal Reverb has you covered. Despite its compact size, this 2x10 combo delivers both stage-worthy volume and the iconic vintage Supro tone.
 
The Royal Reverb is equipped with tube-driven tremolo and spring reverb to give your sound that unmistakable vintage vibe. The 35-watt Class A mode offers a spongy, vintage character, while the 60-watt Class AB mode delivers a faster transient response with maximum available headroom and volume; the 45-watt Class AB mode offers a happy compromise between the latter two. The unique Class A/Class AB switchability provides distinct tremolo voices with a wide range of modulation. The six-spring reverb pan delivers warm and smooth reverb that envelops your notes, from subtle ambience to massive surf-inspired soundscapes.
 
The amp produces virtually no background noise, sounds rich and "wide" and breaks up beautifully at high volumes. 
 
The blue rhino hide tolex, compact physical dimensions and basic circuit topology are all derived from the original 2x10 Supro Royal Reverb combo amplifier.

It is in excellent condition and includes a specially ordered two-button footswitch that allows you to turn the reverb and tremolo on and off.
