good day freestompboxers..

i have this problem on my boston digital delay pedal..its a pedal made from china and bought it online its second hand..
the problem of this pedal when i plugged it on a 9volt power it creates a noise like sort of humming its not actually humming its like "tshhhshhhh".. like that.. its along when the effect is on ..
this is the weird part.. when i plugged the pedal to 5volts only the noise lessen out but the effect still there...when i run it to low like 3volts only clean signal left when the effect is on..

anybody there knows what is the problem of this???

I recently had the same problem with such a switchable wall-wart.
I guess there was no suitable outgoing filter circuit in it.
After using a 9VDC high quality wall-wart the problem has gone.
