I've been looking at many effects to add to my board, however I saw the EHX worm which has 3 of the effects I have been planning to buy individually. If the Worm is any good then I will definitely be able to save some cash (I'm poor). I've searched TB, Google, Youtube, Putfile etc etc and haven't found anything about the EHX Worm on the bass. What I'm after was tremolo, phaser and vibrato. This can supposedly do it all! Opinions?
