Hey guys, I'm building a secondary board out my spare pedals for my P Bass with flats into my Eden WT400. So far the signal chain is; MXR Bass Octave -> OC2 ->Mr Black Fwonk Beta -> MXR Bass Overdrive -> EHX Green Russian -> (Fill in the blank) -> MXR Echoplex Delay. I am looking for a modulation pedal of some sort to fill in the blank. I'm not looking for a chorus (I have one on my primary board). I am open to all suggestions, preferable something that doesn't sound like mud with flats.
