If awards were given for most straight forward pedal names, the Voodoo Lab Tremolo would have to be the winner. If awards were given for most relevant tremolo a decade after release then the Voodoo labs award shelf would start to become a little crowded.
Emulating vintage tremolo circuits found in classic Fender amps, this pedal nails it by using optical circuitry. The addition of a slope control to change the front end of the waves shape allows for delicate ramping all up of the signal all the way up to pure on/off trem. The intensity blends in the effect with the dry signal, using these two controls allows much greater control of the tone than available on the original amps.
Use the volume control to make up and perceived volume drop and even to push your amp like a boost at the same time. Built in the USA these pedals are still as great today as the day they were built!
