this was done by my guitairist with some cheap digitech multi or something similar.. but I like the effect, and I don't know how it is called, so I can't look for it.. I'm guessin it's a modulation, but which? anyway here the sample: www.0wned.ch/snd/unknown_effect_name.mp3 thanks in advance! (oh and if you have pedals doing this kind of stuff to recommend don't hesitate to make me gas... )
It's a random step (aka sample and hold) filter, or possibly flanger. Xotic's Robotalk and Line 6's Liqua Flange are two pedals I can think of with this feature.
I'd put money on it being a ZVex Seek Wah. If you listen closely you'll note that the player comes in partway through some of the steps which I don't think can happen on a sample 'n' hold effect. It might be another step filter (PH-3 can do this), but I don't know any that can get that extreme wah-like filtering other than the ZVex or a maybe Moogerfooger Murf.
damn, I didn't think the means to get this kind of effect were so few. anyways, thanks for checking it out
I use to have an old Zoom 506 with that effect. It's just a synth with a step-changer or something with a name like that.
