1310 Analog Harmonic Tremolo Pedal

The 1310 Analog Harmonic Tremolo is an analog stompbox designed to recreate two of the most desirable vacuum-tube based modulation effects found in American amplifiers of the 1960s. The Supro 1310 Analog Harmonic Tremolo pedal's AMPLITUDE/HARMONIC switch allows the musician to choose between these distinctly different, vintage effects. AMPLITUDE mode provides the traditional swampy, tremolo sounds generated by bias modulating the power tubes in the original Supro amps. HARMONIC mode provides the psychedelic tones of Leo Fender's brownface and blonde amps from the early '60s. Supro has implemented Leo's unique "harmonic tremolo" effect within the output stage of the pedal to create an "amp-like" modulation experience.
