I am planning to make my own inductors by hand for the Tube Buffered Bypass option (Opti-Mu Prime) and for the Mikey Q sidecar for Soul Drive IV. For the time being, I am using some vintage Yamaha inductors scrapped from PM1000 Mixing board channel strips for Opti-Mu Prime (tube buffered bypass version), but I only have a very small number of these. I ordered some ferrite cores to start building my own mini inductors, so it will soon be possible for the "Mikey Q" Sidecar to become available again.
Also, I updated the Opti-Mu Prime page - the Tube Buffered Bypass version is available for ordering. The price is higher than the True Bypass version because there is some added electronics which are pretty serious. The tube buffered bypass was painstakingly tuned to provide the purest tone possible for long cable runs when the pedal is bypassed. Opti-Mu Prime
