Our friend at Bassfuzz.com rated the Swollen Pickle higher than the PPB. I did a side by side between the Wren and Cuff Tri Pie 70's and the EH Bass Muff; the Tri Pie won but the differences were in the realm of subtle details. In a live situation nobody would ever hear the difference IMHO.
Since you own both the PPB and the Swollen Pickle, I would love to read your thoughts following a shoot out.
I have an odd love affair with the MK1 swollen pickle that taints my feelings here. There is this little spot near the very bottom that can extrude speakers if you are not careful, and I didn't feel I was able to get that sound with the Pickle Pie B
That said. I am really enjoying the tall font. I've actually considering adding all the muff variant Wren and Cuff pedals damn collection. High quality, usable on both bass and guitar, and excellent customer service. I'd love to see his take on an IC muff
