I’ve got a Russian re-issue Bassballs that does the “laser” sound thing. Kind of a higher pitch whine with a phaser sweeping sound, even when I’m NOT playing a note. I’m pretty sure that it just comes with the territory of an envelope filter in this price range.

However, I’m not sure about the speaker ripping sound. That’s bad.

Have you tested it with different cables? Pop the back off and try tweaking the little trim pots that control the center frequency for each filter. Mark them so you’ll know where the factory settings are so you can set them back later if desired. It may be that the frequency is set to a place that just doesn’t work well with your rig.

Hint: Use a jeweler’s screwdriver (flat) and make very small turns as you play 8th notes whiles palm muted. Obviously this means playing with the back OFF the pedal itself. Once you find a center freq you like move to the other trim pot and do the same thing. They are really interactive with each other so it may take some “dialing in” time.

This lead me to modding my bassballs with external pots so I won’t have to keep the back off all the time.

I’ve seen pics of this mod even on the little Nano versions.

Hope this helps?…
