what does it mean if your cassette deck playback and recording sounds warbly?


what does it mean if your cassette deck playback and recording sounds warbly? I just got a brand new Tascam CD-A580, and my recordings and playback sounds shaky or warbly.

@russ69 thanks man. I’m too late to ask if I can send it back, but I hope I can get them to make an acception.
Last time I checked suck is a verb.
Not sure what someone is who thinks it’s an epitaph.

My latest is a almost new Optima double reverse deck. It plays 4 sides consecutively AND smoothly.
$20 bill in a parking lot 5 miles away.

Love it.
