I modified the Tony Smith CH-70 CHORUS. The Tony Smith CH-70 is an analog chorus. The modification is a fairly well-known one, adding a variable resistor to create experimental sounds. Of course, it can also be used as a normal chorus. Although it's different from the one I made this time, you can search "USAGIWORKS Tony Smith CH-70 CHORUS MOD" on YouTube to hear a sound check if you're interested. *In the video, it oscillates at the end, but it may not oscillate depending on the equipment used (amplifier, connected effects, etc.). #UsagiWorks
