Remember the classic tube amps with that extremely creamy and alluring tremolo? The Vintage Tremolo reconstructs exactly that sound, but it also gives you all the power to adjust according to your taste or mood. If you dig a more saturated expression, just boost the signal. If you want to go really slow and really deep; then adjust the speed and depth knobs. The Soft Mode switch lets you switch between soft and hard tremolo. Don't be surprised if you get the tremors the first time you use the Vintage Tremolo.
