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

I'm the same way with some things. I was looking at a NEW Tascam Cassette. The wife has a slough of her old cassettes. 

A little update too.. It's not your thread.. BUT it's nice to think that, just on loan, kinda', sorta'.

The words are yours right up until you hit "Post You Response".

Belt? It’s like 101 on a cassette player..
MC got it... Clean and inspect..
Retention your tape.
Go all the way one way AND all the way the other high speed of course.. It helps.

I like cassette, don’t like the play back to much, though.. :-)

I’ll put one in the playback rack.. Tascam for cassette, Otari for RtR
Both affordable and available..

Regards
