Very different sounds from the Tr-2. I have one. It's a junky-made pedal (mine makes a noticeable click when I turn on) and the plastic internal power jack for 9v adapter broke! However, it provides the exact effect that I want for my tremolo sound. Capable of extreme throbbing bass effect ie. the song Jennifer from Faust IV. I searched out a lot of tremolos to achieve a similar effect to no success. So, i've stuck with this one even though I know it's not going to live very long.

I'm currently searching for a backup replacement now. If you know where I can find one a heads up would be greatly appreciated!
