Synth effect pedal

[anaxcrosswords]

Hi all
After a heck of a lot of practice I think I'm getting fairly close to the Hysteria (Muse) bassline, and it would be nice to also get close to CW's buzz synth sound. I certainly don't want to spend serious money though.
My bass is an Ibanez SR500 and I keep all the pots dead centre as I don't like tweaking sounds from song to song. I also use light gauge - 35-90 - strings.
Is there a reasonably priced FX pedal that will get me anywhere close to the Hysteria sound?

You could try the Zoom B3 multi-effects unit and create a patch using the suggested settings found here http://guitarpatches.com/patches.php?unit=B3 (there are a few patches for other Muse songs too).
