I'm a big fan of tremolo effect, and so I wanted to get the best one I could find. Without a doubt this pedal is exactly that!!!
It comes with a power supply, and the instruction manual, which is a must read, because this pedal has so many functions that it's almost absurd :)
Just look on u-tube for some reviews, and you'll see what I'm talking about. You can tailor every aspect of this effect, and save it in one of 8 presets, or just have fun in normal mode.
You can assign an expression pedal to control one of the parameters of your choice. It's stereo in, and out, so when connected to two guitar amps, then you can really begin to understand it's full potential.
The built quality is great, and this one will stay forever on my pedalboard, without any doubt!
I can't be more happy with my purchase, and I strongly recommend this pedal to everyone that is interested in tremolo effect. It's worth every cent, and more!!! It's really unbelievably cheap, when I think of everything it can do, and the overall quality. Why are you still reading? ...Go and buy one!!! :)
