Supro launches Analog Harmonic Tremolo pedal

Not content with having rocked NAMM with its newly launched guitar ranges, Supro has now added the Supro Tremolo Pedal to its growing line-up.

Distributor JHS says the £229 (RRP) stompbox is: ‘…a groundbreaking analogue stompbox designed to recreate two of the most desirable vacuum-tube-based modulation effects found in US amplifiers of the 1960s.

‘The 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. Meanwhile, the Harmonic mode provides the psychedelic tones of those classic brownface and blonde amps from the early 60s. Supro implemented the unique harmonic tremolo effect within this pedals transformer-equipped output stage to create an amp-like modulation experience.’

The Supro Tremolo pedal features preamp and power amp sections, with an actual output transformer deployed to recreate the magnetic saturation and coloration of the original vacuum-tube-based effects found in these historic amps. Along with the standard modulation controls for speed and depth, the Supro Tremolo also features a gain circuit that allows the musician to overdrive the output stage, right where the modulation effects are created. The Gain control sets the amount of “preamp” gain in the pedal. As the user turns the gain up, the “power amp” circuit will gradually be pushed into overdrive.

What’s more, an industry-standard TRS expression pedal can be used to control the speed of the Supro Tremolo, with the on-board Speed knob used to set the maximum value. The rate of modulation is indicated by the pulsing LED status indicator.
