Echo dream 2

[carlinb17]

Hello, I was asked to trouble shoot a pedal… and now I need some guidance. It’s a echo dream 2 based on a dba pedal. I get no fuzz whatsoever from the pedal. It just brings up the volume. Delay works so I imagine that the 2399 chip is good. In looking into the pedal it seems wrought with issues on the few boards I could find. I didn’t find any definitive schematic and this one doesn’t use a charge pump. I suspect it’s the xr2206 chip, some of the boards said it runs at 18v but whoever built this put in 16v electrolytic capacitors so I cannot try it with 18. With 12 it doesn’t seem to change anything. I did t know if anyone had any experience or ideas.

Thanks

Is it a new build, or an existing one that started having an issue?

Never worked, the guy bought it off reverb and it never had fuzz. Its not a new build but mostly likely was not working at the start of the build.
