There is a harmonic tremolo fv-1 patch on here (module8, octagon, or build your own eeprom) which is nice. I’ve also built the 1776 cardinal and I think I like it better. Maybe it’s a mind game since it’s analog my brain expects it to be “better”, I haven’t done a blind test. In any case, the cardinal is a fun and very educational build, the documentation is thorough and there are some trimmers that need adjusted based on voltage measurements. It’s also a little pricier than most analog pedals because of the vactrols. And as always with jfets (2N5457s), smd with an adapter board is recommended rather than buying a through hole package since they are out of production and many of us have been burned by fakes from eBay.
