  1. Hey Anders, since you seem to be on an EQ tear, this Parasit tilt EQ is a great little utility circuit to use as an add-on to a build. There is a strip version available but it's not beautiful. Maybe you'd be interested in adding to the blog. https://parasitstudio.com/wp-content/uploads/go-x/u/0065e333-e612-4b07-b83a-29c559a1dc81/active_tilt_eq_pcb.pdf

  3. Verified, I used the SMD version of the J309 and biased to 7 volts as per the PedalPCB doc.

  4. If I use a j201 instead of a j309 does the bias change?
