Macumbista Butterfly Benjolin + Dual AM/RM | Low-gain Electronics

"Updated my v4/5 Butterfly Benjolin to include one of my Dual AM/RM modules. On the left Benjolin i wired it as per Macumbista’s new ring mod block diagram. With the dual AM/RM circuit you can have the modulator do either ring modulation or TZ amplitude modulation. So that makes for some fun. On the right side I wanted to keep the second AM/RM isolated so you can plug in anything you want to it. Far right side has X/Y inputs. Middle has output and mode switch (AM/RM) and i swapped the external input to the filter to a switching jack and wired a banana back to the normal so you can patch anything banana format into it as well. Internally the external banana jack has a trim pot to adjust the gain amount."
