Combo vibration issues or is it just me?

[Twincam]

Ok my gf very kindly bought me a nice new orange combo. It seems on the face of it a good practice amp.

However it seems the have vibration or resonance issues on certain notes. Seeminly coming from the amp electrics area.
Its not the front grill and I've tried it with serval different basses and in other rooms too. Its deffinetly the combo.

Should a new combo be doing this or should I send it back?.
Anyone ever return anything to guitar guitar?

Are the problems there at low volume ? If they are it may be a faulty model...but iff they're at full-bore, then it may just be the limitations of a practice amp.

Which model is it btw ?

(Oh, and what a nice girlfriend !)

Its not at very very low volume but it does make the noise at appropriate living room volume about 9.30 and above on the dial, and the noise is pretty loud early on.
Its the new crush 50 combo. Which seems like it would be a fantastic practice combo apart from the resonance issues.

I think my gf is a bit angry with me tbh for suggesting it isn't right.

I had a combo do this and it turned out after a lot of investigation there was a split it the actual wood of the cab not visible under the covering so must have been dropped at some point.

Well, it could just be bad luck - if you can take it back then it back (and keep your girlfriend happy), then I would.

It's possible something's loose inside.

Yeah think it will have to go back as its not right.
