s 2x10" Flagship vintage reissue with Reverb and Tremolo. This model features a switchable 6L6 based power amp with a solid state rectifier options at 35 or 60 Watts.


"The 1650RT Royal Reverb is the flagship tube amplifier of the Supro 1964 Reissue tube amplifier line. This retro-modern masterpiece updates the mid 60’s classic with an all-tube feature set designed to deliver superior sonic flexibility and ample headroom along with enough stage volume to handle any gig.

The blue rhino hide tolex, compact physical dimensions and fundamental circuit topology are all derived from the original 2×10 Supro Royal Reverb combo amplifier. Like its vintage counterpart, the new Royal Reverb’s power tube tremolo comes after the reverb pan, lending an ethereal shake and wobble to the enveloping wash of tube-driven spring reverb.

Independent TREBLE and BASS controls in the preamp provide enhanced tonal control while our unique, 3-way switchable power scheme allows the musician to coax a wide variety of texture from the 6L6-fueled power amp. The 35-Watt Class A, Cathode-bias mode delivers a more spongy, vintage character while the 60-Watt Class AB, Grid-bias mode achieves faster transient response with maximum available headroom and volume.

The unique Class A / Class AB switchability of the Royal Reverb model effectively equips this amp with two distinct tremolo voices. Set to Class A mode, the tremolo is pure vintage Supro, with its distinctive asymmetrical rhythm and overall depth dependant on how hard the output tubes are being pushed. Set to Class AB mode, the tremolo gets much deeper, with greater symmetry and overall range of amplitude modulation.

The Supro Royal Reverb carries a long, six-spring reverb pan with all-tube reverb drive; recovery stages provide warm and smooth ‘verb that “surrounds the note.” From subtle ambience to massive splashing surf madness, the Royal Reverb lives up to its name in every way.
