Description

Edit description

With its warm analog circuitry and lush tremolo sound, the Dunlop TS-1 set the standard for tremolo pedals for over a decade. The MXR M159 Tremolo keeps all the effects and controls of the original—but in a smaller, pedalboard-friendly size. Its 18 volt operation provides rich and vibrant sound with low noise due to its high headroom. With the versatile input/output options the M159 can produce hypnotic, pulsing mono tremolo through a single amp or ping-ponged from one amp to another in stereo mode for a huge, spacious tone.

Lots of flavour with this one.

Being a tone chaser that I am (and a effects guy that I am) I always wanted a tremolo because I used it on my BOSS ME70 before and wanted to get the same effect with pedals and got the exact effect I wanted.
