I just purchased a Psk Chorus pedal

when I got home I pluged the lead from my guitar into the pedal then another lead from the pedal to the amp...when I turn my amp on I can cleanly hear clicking which is controled by the rate knob...Is this normal? (Im new to pedals)

Im gonna try running it thru the effects loop later (just need to get another lead)

Sorry but im really new to stompboxes
how do i find out if its true bypass

and if its not...will I still get the clicking with the effects loop?
um I hav looked and cant find anything...shouldent it say somewhere...shouldent all pedals be true bypass?

oh and i hate ocates cuz all those crappy pop bands allways play a few of them half way thru a song and call it a solo :P
