I've been mostly playing upright for a couple of years so my board has been a bit neglected. I've got an Octavius Squeezer on there which has some great filter effects but no expression socket. I've also got an M9 so I'm currently using its Q Filter for a treadle filter but the gain boost gets me down and I'd rather free up a slot on the M9 by using a dedicated filter pedal at the end of my chain. So I was looking at the Sonuus Wahoo but apparently that has software issues. So then I was looking at the Xerograph but IE aren't taking orders right now. An MF-101 is cool but just too big, I don't have the space for it. So what do I do?
