Hi all,
I’m plagued by an issue with some optical tremolos which I can’t seem to resolve, where I am hearing a ‘fizz’ in the tremolo when guitar signal is passed through. In some cases the fizz is only present in the peaks, when the volume is at the highest, but in the sound clip I just recorded it seems to be present whenever guitar signal is passed through. I first had the issue with the pedalpcb harmonic tremolo, and since then I’ve built the coda effects montagne tremolo which uses an electro Druid LFO. In my pedalpcb build I used a pair of LEDs and LDRs and in the coda effects build I used a vactrol. Both display the same issue but the pedalpcb fizz is more obvious. Hopefully the video clips make the fizz clear. The fizz gets quieter and eventually disappears the more I turn my guitar down, but that’s not really a solution lol.
Has anyone experienced this issue before, or does anyone have a possible solution? Both effects work as intended, but I refuse to believe this is just an issue that plagues every optical tremolo out there
