Behringer UT300 Ultra Tremolo Pedal - Second Hand
This vintage style tremolo captures the warmth and natural harmonics characteristic of tube amps made in the '50s and '60s. Instead of a single intensity knob to control both the rate and depth of the effect, the UT300 lets you dial in each setting separately, offering up a wide range of effects. What's more, Behringer gave the UT300 a Wave control, which lets you change smoothly between a softer triangle waveform to a harder square, allowing you to more closely emulate transistor or optical tremolos.
