I had a DiscumBOBulator, which is an envelope filter. I got it because it's widely regarded as one of the best ones out there (at least of those for which you don't have to shell out $600+). I sold it because I wasn't using it as much as a pedal of its stature should be used, but it was a first-rate envelope filter. Super cool.
If the other EMMA pedals out there are in the same class, you're sure to be getting an excellent effect.
I have a ReezaFRATzitz pedal in my collection and it's great
I find it to be quite a versatile beast, but find it a little too bass heavy for use with my Orange amp. If it wasn't for this, it'd definitely be on my live pedalboard
the reeza is a sweet pedal. i had it for a while but i sold it because i honestly havent found anything i love as much as my modded ts9s. nothing else seems to get that sound.
but the reeza is a solid pedal, very very good at what it does
