So I picked up a fender princeton on craigslist a few days ago for $100- couldn't pass up the deal. It's the dual speaker combo with reverb and chorus, however neither of those functions are working. The clean and overdrive channels work fine, but the two reasons I bought the amp were the chorus and reverb.

I'd rather not take it in to a shop if I can avoid it- I've got other amps I use more and this was just an impulse buy.

Any suggestions?

Thanks guys

They may not work unless the foot switch is enguaged. Kind of like the old tube amps the vibrato/reverb would not work if it was off then the switch was off then removed.  Try that first before spending money to get it checked out. Aslo make sure the effects are not opperated by a push pull pot on the amp.

The footswitch doesn't seem to matter. To activate the chorus you must press a button on the amp, for the reverb it goes both ways.

I'm not sure if it is a push-pull pot setup. It's an older model, definitely nothing new.

I was toying around with it last night and the chorus came on momentarily and then cut out. I had the chorus channel activated. The same with reverb - it came in and then cut out.

Try kicking the shit out of it it's solid state not tube. it will knock the dust of of it.      Seriously go to radio shack by some spray called deoxit 5 pull out th chassis and spray the hell out of the pots and switches. Its probably just dirty contact points.

10-4 on the dirty pots and switches. First thing to check/fix.

If you can get the chorus to work, but not the reverb, worst case scenario the reverb tank is shot (it happens). But these are readily available and easy to replace.
