roland cube 30 warbling

[oliverf]

Hi, just joined. Hopefully you can help!

I bought a few months ago a second hand roland cube 30. It's about 2 years old.

Anyway, the other day I noticed it is making a slight "warbling" sound, especially noticeable on the higher notes. Almost like a bit of chorus is leaking through. How do I fix this? It's solid state.

thanks

Do the chorus controls affect the warble? - chorus/FX switching
No effect? - PS filtering.

Well I tried turning off everything - effects, tone, reverb.

Anyway, as of yesterday the warbling is gone! I don't know why. Thanks for the reply though.

Oog - a ceiling fan can do that - was one running, and lately turned off? So can a loose connection or cold-solder joint.

Interesting. I'll play around with my appliances.
