An amazing pedal!

I have tried a hundred different trem pedals and this one is by far the closest match to a tube driven amp's tremolo. The tremulator was built to mimic the gorgeous tremolo (vibrato) of a vintage blackface Fender amp. It sounds smooth and lush at almost any setting. It has a much smoother and dare I say musical quality missing on most tremolos, even one's on an amp. Personally, I enjoy it more than the tremolo on silverface Fenders and even the Supro Jupiter's. Only real blackface Fender and Vox AC tremolo sound as pleasing to my ear. There is a slight volume boost when engaged to compensate for the ''soft'' nature of the effect. The switching is silent. If it's good enough for Ry Cooder, it's good enough for anybody!
