Hello pedal builders!
I need some help figuring out why my Klon kit doesn't sound like it should.
I purchased the Klon kit from Aliexpress a couple of weeks ago. After some hours of fiddling i managed to get it working, but the sound is really weird. It's hard to explain but it's noisy, almost fuzzy, but not in a good way. Here's a short clip of how it sounds:

I followed the instructions on the black and white (not super clear) instructions that came with the kit and got som help from this blog post:
https://guitargearfinder.com/guides/build-klon-centaur-clone-kit/. This is the same kit as the one I built.
During the building process i made two mistakes (that I know of). The first was that i oriented one of the 4001 diodes (the one to the right) the wrong way. The second mistake was connecting a battery with a DC-plug in the DC-jack. I think that the DC-plug was center positive. Anyway IC1 (7660) was slightly warm after unplugging the battery. Could i have damaged it? And could this be the reason why the pedal sounds broken?
I toke som readings with my multimeter. The battery read: 8.99v. When reading from ground (enclosure) to plus on the PCB the reading was 8.05v
