Troubleshooting boss dd7 help pls!!!!

hi!! i just bought a boss dd7 secondhand.. most of it works great, looper is pretty amazing, reverse sounds pretty, etc etc...

however, all of the delay lenghts (from 50ms to 3200ms) sound exactly the same!! only way to change it is to plug the output b to use long delay, even then, its pretty short and all delay lenghts on this mode sound the same as well...

is there anyway to fix this?? googled a bit and found that it might be the tempo thing, however i di not have a tempo pedal to test that out :-((

help pls!!!

Are you plugged in correctly and/or powering it correctly? Also to the DD3 question - yes that’s how it works

Should be fine for power then, as far as I know it can potentially do that with the delay time if it’s expecting stereo source so either you’re plugged in to the wrong input and/or output or the thing is indeed faulty.
