The Korena take
Supro's Analog Harmonic Tremolo is an analog stompbox with two distinct modulation paths. The AMPLITUDE/HARMONIC switch selects traditional bias-modulated tremolo or the harmonic tremolo effect associated with early-'60s brownface and blonde amplifiers. Speed and depth set the movement, while the gain circuit can push the pedal's power-amp section from clean toward grind. Output compensation keeps the signal level consistent as gain rises, letting you alter the modulation texture without a corresponding jump in level.
Strong match
Who this is for
- Switching between traditional amplitude tremolo and harmonic tremolo from one analog stompbox.
- Using gain to change modulation texture while maintaining a consistent output level.
- Controlling modulation speed from an industry-standard TRS expression pedal.
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Gain with automatic output compensation
Increasing gain pushes the power-amp circuit toward overdrive without an overwhelming rise in output level.
Detail 03
TRS expression-pedal speed control
An industry-standard TRS expression pedal controls speed, while the onboard SPEED knob sets its maximum value.
Detail 04
9V battery or AC operation
The pedal can run from either of those power options.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the difference between the two modes?
AMPLITUDE provides traditional bias-modulated tremolo, while HARMONIC provides the pedal's harmonic tremolo effect.
02Can I control the speed with an expression pedal?
Yes. An industry-standard TRS expression pedal can control speed; the SPEED knob sets the maximum value.
03Does turning up gain also greatly raise the output level?
No. The pedal automatically compensates overall output level as gain is increased.
