I have experience making Phase 90 from BYOC. BYOC's Phase 90 kit have 6 of UA741 opamp chips and speed is so slow. I changed opamp chip to LM741 and speed is more fast like any other Phase 90 pedals.Great job. Very nice build and thanks for explaining your settings.
I also noticed that the Speed range is not wide. I'd like it to go much faster with the knob maxed out.
Is it possible to widen the Speed range by changing some of the component values and if so how?
Can this method be applied here as well?
