Thanks to all that have post your replies.
I have never tried whammy-IV cos nobody that I know owns one. Bass whammy is almost impossible to find here in where I live

. Boss PS-3 is something that I have been looking for for quite sometime now, but haven't had any luck

. But my cousin who also plays bass just bought one so I might try his out.
Other than whammy and Boss PS-3, are there any other pedal that do similar thing? Preferably the one that is still in production. I know Boss has PS-5 but it's not quite like the PS-3. There's also behringer fx600 that can do pitch shift, but I try to avoid behringer for reliability reason (although I own a couple of their pedal that still work fine but they feel a little flimsy).
I'll try and search the forum.
Again, thanks for your replies
